Link LED indicator function of fault diagnosis

May 8th, 2012

Daily network one of the most common fault is the site not Internet problems. And PC users or network maintenance personnel first thought is to look at the network card or switch (or HUB) led to determine if the connection is fine (usually this is the right step for fault diagnosis of), then Nikon EN-EL4A Battery Charger from the PC, check the software’s settings, and Nikon Coolpix S6100 Battery Charger  so on. But the LED light is able to pass on the network card or switch to see if cable or port problems? Practice has proved that, precisely because the LED’s indicate that make errors of judgment, in resolving the failure that we could find a problem in the wrong direction and thus wasting a lot of time. LED lamps in the troubleshooting to be able to have any help?

Experienced imaging experts on the benefits of combining projection and DV-projection

February 8th, 2012

Sony launched the PJ camera projection series, since its listing, widely favored by the users, PJ camera projection series combined with traditional digital cameras and projectors, implement user willingness to shoot that is ideal. JVC GZ-MG750BUS Battery Charger I as an image in addition to shooting enthusiasts had more than a dozen years, the following summary of several points to slight Sony bring immediate benefits of this innovation to our users.

A share, at any time, free

Combination of projection and DV

Its root causes, since the consumer DV, to document the reality of life and is good at, its easy handling to let people easily get started without any photography based; small volume allows us to carry around anywhere, anytime. As diaries, novels, photographs, music, graffiti, and so on, we just convert a vector to a record occurs in or around some of his ideas. After the completion of the video to your Favorites or share, which is our ultimate goal. Having said that, I believe we have been very clear, why the combination of cameras and projectors will be so much sought after? Because this really is the people’s will to, the product itself in addition to all of the features can do a normal DV, also joined the projection function design, human consideration, meet the needs of most consumers, users can switch to when and where the projection mode, and share your own pictures are images.

Second, cost savings, a multi-

Combination of projection and DV

Traditional of video making process in the, we needs in early viewfinder shooting to late edit in the experience a complex of work process, to see we shooting was image, course, now of most consumption level camera is using store card to for records of, this for we save has traditional in the video making in the collection footage by consumption of large time, but, regardless of which species storage way, to last needs watch of when, we are to with a Terminal play device to image play out, out tourism, Thin convenient of output device size Panasonic CGA-S303E/1B Battery Charger small; large of device and impossible carry carry; portable of projector most price expensive, price does not high; so we often disappointing ended, however, if’s DV and projector combination in together, we on without then worry so of problem occurs, fuselage can cast photo high zoom clear of picture, and can cast in any of local, easily and people share, especially tourism of when, without back this heavy of projector, reduced luggage burden of while, You can also watch the themselves take a HD screen, really shoot your car, on the road, will add more fun.

Third, environmental health, conserving resources

Combination of projection and DV

We know, projector is to accurate of zoom rate will object zoom projection in projection screen Shang determination object shape, and size of Nikon Coolpix S220 Battery Charger instrument Shang, is widely for now of meeting, and teaching, and Office and so on places, internal by high lighting bulb glow lit, most projector bulb life more short, besides, in usually watch themselves shooting was some small screen of when, is not needs so large of zoom rate to and high lumens of device, so, consumption level DV since with projection function must degree Shang also for social savings has resources.

Combination of projection and DV

Above, DV camera combination projection function meet has is large part consumer of daily needs, real implementation has anytime, anywhere share happy of wishes, in past of a years in, Sony launched PJ projection series camera was general user of favored is expected of thing, they to consumer assumes that of situation became has facts, DV and projection perfect combination, is bound to will to market brings must of impact, insufficient of Department is currently of products only play this machine shooting was video, Copy out of video files do not play correctly. However, in this new concept was born in the first batch of products we see unlimited potential and Sony’s superior technical capabilities, we expected Sony to do better, gives users more surprises!

30 lumens is the limit? Micro projection n to use in the future-miniature projection

January 12th, 2012

Since the LED light source applied to the projection techniques, some vendors begin work to make the projector’s volume constantly goes down. LED light source because of the heat is very low, while also greatly  Nikon MH-53 Battery Charger simplifies the internal structure of the projector, so volume is reduced to 200 grams of projection products, allows us to easily placed in the mouth, hence the name “Pocket projector”.

Micro-projector road ahead

Although the volume of the compact, will allow us to easily carry, but also because the volume is too small, miniature projector is oversimplification in performance, functionality,. In particular, its current level only 10 lumens of brightness, can only cast a smaller image, while requiring some high ambient light.

Micro projectors after the listing has been questioned a lot of people, only 10 lumens can be used for the product of people buy this product can do what?

In fact, all micro-projector and dont worry too much, as technology advances, you can have it applied to all areas. Through technology continues to progress and expand the scope of application, in all kinds of IT equipment in the future we can all see the projector’s shadow. The following, let the author to speak for you, miniature projectors are all thinking about what direction.

Performance improvements of micro-cinema is not a dream
At present, micro-projector is to be solved on picture quality problems, low brightness, resolution below the mainstream products, making it difficult to meet the General needs of users.
First, brightness, currently in mass production of micro-projector, usually on the brightness around 10 lumens, highest JVC BN-VG107U Battery Charger product can only reach 15 lumens, and brightness become technical bottleneck of micro-investment and development. And in 2010 on integration system of European audiovisual exhibition, auto code showed a model to H03 micro projection products, its brightness is increased to 30 lumens.

Brightness auto code already raised to 30 LM PK-301
Although 30 lumens of brightness for projection devices, it is at a quite low level, but with the LED light source technology advancements, brightness to uplift is only a matter of time. Recently we have seen the use of LED light source for projector brightness has been increased to 1000 lumens, believe soon, miniature projector brightness will have significantly improved.

Second is micro-projector resolution is lower than the mainstream level, due to size issues, 0.17 inch DMD chip DLP can only be achieved 480×320 resolutions. Domestic product using LCoS technology, level of resolution can only be 640×480.

However in this year’s 3GSM exhibition on Texas instruments has released the latest research and development of WVGA DLP Pico chipset specifications, the chip before the resolution of 480×320 up to 854×480, pixels up to 2.6 times times, could pose a more delicate drop shadow effect.

At the same time, we also micro-projector manufacturers have conducted exchanges with the Mainland, LCoS technology has high resolution, highest-resolution level can achieve 1920×1080 full HD, most likely a home theater display  Panasonic Lumix DMC-FS37 Battery Charger devices. Although there is no product launch, but we believe that the future of micro projector will definitely towards more development of high brightness, high resolution.

UWB opened up a new era in home consumer electronics

November 10th, 2011
  • Radio ultra-wideband (UWB) is a rapid development of new technologies, it will dramatically improve the consumer’s home entertainment experience. Consumers are starting to use PC and a laptop at home enjoying the advantages of wireless technology and wireless technology would soon make family entertainment products also benefit from. UWB will achieve speeds up to 110Mbit and even faster wireless connections so that it is ideal for connected TVs and DVD players and recorders, personal video recorder (PVR), as well as home stereo equipment.
  • UWB application applies to two categories of consumer electronics. A class of application is within the room, such as set-top box and DVD player to  Samsung SLB-07A Battery Charger  the wireless connection of digital television, this class of applications needs at least 20-28Mbit per second transfer rate, in order-in-picture feature you need to 56Mbit per second transfer rate, also need to 7-10 metres distance to achieve multiple channels of transmission. The other is a desktop application, such as PDA, mobile phones and digital cameras and PC synchronization, such as PC based video editing. This class of applications generally need to support transmission distance of 2-4 m, but requires a transfer rate is very high, sometimes up to 480Mbit/sec transfer rate.
  • Each consumer to see behind the screen to do a mass of cables and wiring have a skinful of grievances to, connect to the new home entertainment equipment trouble and it goes without saying. Has encountered because most consumers do not know how many connectors and cable experience headaches, and for how you want to have a bunch of wires and cables hidden in the limited space and worry about. These troubles will cease to exist, what if we buy a new DVD recorder home, plug in the power supply, switch, sit down and wait a few minutes, VCRs had no trouble with television and audio equipment to establish permanent wireless connection.
  • Despite the almost countless number of UWB applications, but the most immediate need is to be in the area of household consumer electronics established a wireless solution. As consumers upgrading to HDTV and flat-panel TVs, a major upgrade cycle is in progress. Consumers see commercial advertising display hanging on the wall in the living room beautiful flat-panel monitor, but often these ads are not showing display back down below the walls of three or four cables. UWB cancels all connections to Nikon D70S Battery Charger  the cable set-top boxes and DVD (unfortunately, power cord, which continued until the day when someone came up with how to provide wireless power sth )。 UWB is not seeking another technology solution, but a view of the current requirements of the solution.
  • UWB is also expected to meet other important needs of domestic consumers. Cable and satellite providers are rolling out more and more high-definition television broadcasts, it usually takes standard definition signal bandwidth of about five times. UWB has 110Mbit per second data transfer rate and transmission distance of 10 metres, so only it in housing in almost all the space from set-top box to the TV monitor wireless transmission of high resolution video streaming function. That makes consumers do not need to procure new set-top box for each TV, you can enable more than one television is received to the original source of HD programs.
  • Of course, other home entertainment products will benefit from “cancel connection”. Handheld game consoles, as well as those who are using the front panel connector products (such as digital cameras, etc) are very good examples, the wireless connection will make life more convenient for consumers. UWB also will eventually meet a handheld electronic device (such as MP3 player and PDA) low power requirements, is the most important, it provided was widely accepted by consumers required a low cost solution.
  • Interconnect family entertainment system also means providing extremely high signal quality. Although wireless file transfer in the application similar to the PC will allow temporary decline in throughput capacity, but transferred to the TV monitors wireless signals do not appear in this case, or consumers will immediately abandon the technology. UWB to provide the required high quality signal. In the living room where intensive, it will be powerful and reliable, even the family dog in between the camera and TV go everywhere can maintain a high level of image quality. In addition, whether or not between the signal source to the monitor can be open, as long as consumers take them within 10 metres of any place, have the function of UWB products are able to work without any problem.
  • Finally, UWB and other wireless products in the family must be (such as Wi-Fi home networks and cordless phone, etc) peaceful coexistence. Because some of the above application the operating frequency and Panasonic Lumix DMC-ZS1 Battery  assigns FCC UWB is the same as consumers worried about buying equipped with UWB newer televisions can interfere with other wireless products, development of UWB standards will ensure that such worries are unnecessary. All of these products is truly user-friendly turned out, is that consumers don’t have to care about them at all what is UWB, Wi-Fi or Bluetooth. Each of these technologies will be a natural solution for a class of wireless products and seamless coexistence, while consumers there’s no need to worry that their standards are “802″.
  • End users may be concerned about the relationship between UWB and other connection technologies. In the technology of digital connections, without outside of 1394b, USB2.0 cable, and wireless Wi-Fi and Bluetooth. Wi-Fi and Bluetooth as its transfer rate limits, can only be applied to the data network, is unable to meet the needs of consumer electronics. In the cable connection, USB is more suitable for computers and  
  •  peripheral equipment, 1394b and UWB applications in the same level. What is UWB for wireless or wired 1394b, depending on the actual situation. For example, 1394b need wire (very low non-shielded category 5 UTP), for a newly renovated home is a good choice, but to the old home decoration, UWB is more appropriate. On the technical level, UWB wireless 1394 technology development is basically came from, so users have no need to worry about compatibility between the two interfaces.
  • Currently in UWB standards development, there are two camps. Party is led by Intel, Microsoft and other companies, including the vast majority of global software and hardware vendors; the other is a three-headed by Motorola company. But this does not indicate who will win in the near future. We believe that for a long period of time, the two standards will coexist. But for users who don’t have to worry about this problem. As CDMA and GSM handset, the user is not in use can feel the difference between them, real distinction exists only in that operators and equipment vendors.
  • In January of this year’s Consumer Electronics Show in Las Vegas, already some UWB set-top box presentation. We expect that by the end of 2004, will see UWB devices sold on the market. UWB real mature and enter the market will be in the second half of 2005.
  • UWB showed clearly that the future prospects for household electronic equipment easier times. The industry must be through the provision of standards and technology work together to achieve the potential of UWB, it will make future household electronic products consumers life easier, by that time will have more products and features to choose from.

Using digital camera CMOS technology project design

October 12th, 2011
  • Using digital camera CMOS technoloWhat is a CMOS digital camera? For end users, the digital cameras traditional cameras using CMOS technology is not much different. Most photographed operating methods, and in the viewfinder to the correct position of the object being shot in exactly the same. That different from where? Traditional cameras need to use a 35 mm film for exposure and store images, and uses a CMOS sensor digital camera exposure, store your photos using the built-in Flash memory or removable storage card. But this is not all, of more complex problems from the process. CMOS sensor is composed of a photodiode array, when taking a photo, CMOS sensor exposure, then read the image data. This information is sent to a coprocessor or back-end directors. The coprocessor is responsible for all processing, until it was in any of Panasonic HDC-SD20 Battery Charger  the images are compressed and saved in the memory. Although coprocessor to handle all the problems, but we should see it in sensors and lenses during the imaging process is very important. Even if the coprocessor has very complex image processing capabilities, if serious false image data, then it is impossible to completely fix. Although the imaging process is complex, but there is still a simple solution.
  •  
  • In addressing these complex issues, STMicroelectronics has a wealth of experience. The STv0684 coprocessor and VC6700 (2 million pixels) CMOS sensors are supporting one of the 2 million pixels or higher-resolution solution. To the user, we provide the tools is not only a chipset, and is a turn-key solution. We will provide a list of circuit schematics, BOM, firmware, drivers, tools, and support and advice.
  • Now, let us look at the product features and benefits. VC6700 CMOS sensor uses four transistors (4T) configuration and H8i (0.18 μ m) manufacturing process. This means that each pixel on the sensor has 4 transistors, which have a particular advantage in low light conditions, but ordinary CMOS sensor the greatest difficulty lies in low light image is poor. With the help of this technology, ST’s CMOS sensor to reach the low light performance is very close to CCD. As we all know, CMOS and CCD has other advantages in comparison: the use of single-supply operation and low power consumption; logical circuits can be integrated into the same chip, so as to reduce the number of external passive components. In addition, VC6700 has been built on and 3.3V linear regulator, when using USB or charging the battery power, linear regulators with external power transistors together regulate the remaining circuits of power. We also has a built-in audio preamplifier for recording, it makes the audio circuit is simple, simply connect the microphone. Is one of the main characteristics of our sensors with 48MHz or 48 million pixels/sec read speed, which makes it possible to achieve the 25 fps (frames per second) video transmission rate. This feature allows us to use this solution without a mechanical shutter blades. At the same time, it requires a coprocessor also must be able to handle the speed of the data, otherwise it may cause picture distortion, such as image slices. Occurs when a data read speed too slow image slices. Then came into sight is a fast moving object, since the sensor reading order in accordance with the principle of a rolling shutter-by-line reading from top to bottom.
  • Figure 1 illustrates the STv0684 characteristics, this device is the core of the system, is responsible for controlling all processes and systems.
  • Contrast the STv0684 and other similar components, we discovered that there are many differences, particularly in terms of video pipeline. We have two independent processors within the same system, which can radically improve the overall performance. VP (video processor) is a hardware module and a high-speed 8,051 composition similar to the controller. This design has an edge in comparison with other solutions. Controller and hardware module and system independent, so the host controller (in this case is the ST20) will not have to deal with image quality-related functions, such as AE (automatic exposure), AWB (auto white balance), color and image concerns. These high strength calculation and operation tasks were evenly assigned to the various firmware, regardless of the speed-related actions performed by hardware module. In order to make the image quality more reliable in harsh environments, our video processors to increase the recalculation a virtual photon prevention function of Nikon Coolpix 4300 Battery Charger  lens shade, reduce fixed-pattern noise (FPN) function (to remove does not expect to see vertical line), without having to make any special settings on the production line fault pixel processor error correction and advanced statistics. Video processors from main kernel of common firmware firmware can change at any time. Main kernel is a proven ST20 32-bit RISC embedded controller, the device is also used to ST many other multimedia solutions. The kernel of the operating frequency is 48MHz and can provide the system with the power of the power and flexibility. ST20 special is that it’s Embedded RTOS OS20, the RTOS can further improve system stability and flexibility. The STv0684 first started from the boot ROM memories, then store provides several possible options for the code. Programme is code that can be stored in a small package size of the SPI flash memory, or if there is a NAND Flash memory can also boot from NAND Flash memory. In this case, you no longer require external NOR Flash memory, thus saves valuable PCB Board space. Next, the code is loaded SDRAM memory, for the processor implementation. For this characteristic, we built a DMA-driven NAND Flash, SPI and SDRAM Controller.
  • Digital cameras and camcorders working characteristics of the chip required are as follows:
  • For portable devices, it is most important for advanced power management features to extend battery life. It allows power down the system at all levels of unnecessary hardware module, when you do not need high performance, it can also reduce the frequency of the CPU. Under the system status, this design power consumption can be further reduced to 6Ma. Of course, the chip also supports standby and other necessary functionality such as USB.
  • Built-in USB1.1 interface, for downloading pictures and PC-camera connectivity. Cameras support three USB mode: one is MSCD (mass storage-level equipment), without PC machine installed drivers, support drivers for Win98SE presets we provide. PC-camera connectivity, we offer two options, one is our proprietary-compatible video driver, the support of our driver without installing driver.
  • Built-in TFT controller to directly support no controller monitor module. The controller must be flexible enough to support different manufacturers, different types of browsers, and supports up to 1024 x 1024 resolution.
  • Built-in NTSC or PAL standard TV output. Output it through software changes and any resolution image can zoom into correct format.
  • Built-in audio codec in order to record and play files WAV compression. Audio compression ratio can be as high as 4:1.
  • Built-in interface for removable media storage, like CF, SD, MMC, SMC, as well as possible micro-drive.
  • Finally, another method is to save storage space compress pictures and video, so we built a compression engine. The compression engine (VC) supports up to 100:1 of JPEG compression ratio, and in practical application, 35:1 compression ratio is acceptable. This is an important feature of the system is superior to other solutions, because alternative solution compression ratio and half of its requirements are difficult to achieve, so customers are forced to buy bigger capacity storage. In addition, the compression engine to encode and decode real interleaved AVI file, the file is a standard in many platforms, including PDA (personal digital assistant), PVR (portable video recorders), PMP (personal media player) and PC.
  • Of course, we take advantage of this opportunity to chip a lot, because the chip has a much higher than required by the digital camera design flexibility. In the consumer electronics market, we will see more and more product integrates multiple functions in one device, such as handheld product called PMP can play MP3, store pictures and movies, listen to FM channels, Exchange data, play movies and other media. The market takes on a boom, so, we will further take advantage of this chipset development solutions. As we increased to more than 3 million pixels and the resolution of the sensor, we still believe that the market will be between 2 million to 4 million pixels, as pictures print shop printing 5 “x 7.5″ normal photos just 2 million pixels of size. If we improve the resolution of sensors, it doesn’t make any sense for excellent image quality. A higher resolution only if we print a large picture or zoom in on a certain area will play the role of improved image quality.
  • Now there is increasing talk about MPEG4, we are planning to integrate this functionality with next-generation chips. We see other solutions on the market today support features such as MPEG4 (low profile) standard, but by a more detailed analysis, people found that it only emphasized packaging, and in fact, compression MPEG4 (low profile) file bigger than the standard AVI compression file. Therefore, we believe that ST enhanced AVI file compression ratio is a more superior movie quality solution, because it takes the QVGA format can support 30fps of transfer rate. As regards royalty, every device manufacturers must consider a value than free compression scheme to pay money sense.
  • Now back to CMOS technology topics. CMOS technology is stable development, we believe that this technology is very promising because CMOS sensor flexibility later, operation easier, less costly. For example, on a mobile imaging market, we see it already accounts for JVC GZ-MG40 Battery Charger a certain market share, so we will see in the future of digital cameras or digital cameras the same result. Because the pixel dimensions further narrow, increasingly high quality, we believe that this is the trend of the future. But it is worth noting is that if we set the CMOS technical comparison between products and high-end products, we must for CMOS technology using higher quality lenses, and even devices equipped with auto focus and auto zoom. As we are currently working to solve this problem for customers, use of CMOS technology and the differences between other technologies will be eliminated sooner or later.

Create panoramic images easily

September 9th, 2011

If everyone in the postcards, the exhibition looked at some panoramic photos (Panorama), I believe will be ultra-wide viewing angle and ultra-realistic scene brought a sense of JVC GR-DV500 Battery Charger  deeply attracted. Some film cameras can shoot before the so-called panoramic photographs, in fact, just the film on the lower half covered, view or no increase. To take a real panoramic photos, you need to use specialized and expensive equipment. But this is different from past, as long as you have a digital camera and suitable software, as you can create panoramic images with a taste of the fun!

Equipment preparation1 digital cameraBasically any digital camera can be used to take panoramic photos, but still have a basic tripod socket. Some digital cameras have panorama assist shooting mode, you can help us more accurately capture the number of photos for a series of Panasonic SDR-SW28 Battery Charger  connected purposes. If we want to create a high level of panoramic photos, it has a manual exposure mode to use digital cameras to capture the exposure of the same photo. In addition, if the angle of the camera’s LCD can be long on spin, framing naturally more convenient!Canon PowerShot A80 built-in shooting modes, Panorama assist,Can easily take panoramic photos. A80’s LCD by multipleAngle adjustment, we will not be tired a long composition.If the average brightness of the photo, it is best to use full manual exposure mode shooting.2 TripodIn fact, the current panorama shooting synthesis software can allow a small error, if only impromptu shooting without a tripod is also acceptable. But hold up the tripod can make a more accurate composition of fine-tuning, but does not feel tired, take a long time, if you can still carry the good. The size of a tripod you have to depend on the weight of the camera, but the best choice that can be adjusted independently in three directions, and in turn the camera will not change the vertical direction. If you stand with rotating scale, then it has to meet a professional shot!The Manfrotto 141RC is a classic 3D platform.Attractions selectionAs the digital panoramic photograph from the synthesis of multiple photos, photos of connectivity is the key to success. Select the shooting sites, avoid other people choose downtown or where vehicles as pedestrians or vehicles once connected spaces appear in the photo, to the next shot time and has not in the same position, synthesis out of the picture may appear “half a person” bad situation. On the other hand, the location of the environment but more broad vision of Nikon D200 Battery Charger  the best, if there are too many scenes of varying distance, photographs and pictures will be different perspectives between the synthesis out of the picture there may be lines can not overlap situation.Too many people in the photo, bit easy connection “to wear collapse.”If too many close-ups, the camera perspective effect and role of connecting the software, had completed a straight pole bending.FilmingEffort to do his homework, when they officially take much simpler. In making a good photo, then rotate the camera left or right until the edge of the screen to keep up with the edges overlapping a photograph will make another one, in the case who were all photographed the scene until the desired date. Canon digital camera has many shooting modes panorama assist, appear on the screen blur the edges of a photo to help you compose, shoot up much more convenient. If we do not use the digital camera shooting modes panorama assist, with the memory of a photo shoot on is also possible, but is not so convenient and accurate.If a tripod, when the first shot should pay attention to the level and composition of photos, try turning the first level the tripod platform, see the last photo shoot when the like. If you have taken a 360-degree horizontal line or the horizon of the environment, just a point each turn you can press the shutter, the time scale of a tripod can make the angle of rotation is more accurate. But if you take pictures that have a coastline (with a different level!), For example, taken in Tsim Sha Tsui waterfront view across the harbor, even if the correct level of the first photo, the perspective of the relationship, take a few more and then we will find the coastline oblique, this panoramic picture will be wasted! Actually encountered this situation, take a photo of each have to re-adjust the level of  Fujifilm FinePix J37 Charger the coastline and high, so that each photo of coastline height and more consistent level, composite photos will be more natural.When the first shot should pay attention to a high level and the coastline.Software synthesisThere are many easy to use panoramic synthesis software (such as ACDSee Photostitcher), but many digital cameras, such software has been bundled as a value-added products, such as all Canon digital cameras are supplied PhotoStitch software, a few simple steps to complete synthetic procedure, we can not waste. As easy to use and good results, this time we will try to use Canon PhotoStitch software to use this type of demonstration.

Reflecting our special Red of Lotus–summer tour-Dutch shoot fun

August 5th, 2011
  • Summer, recently emerged high temperature weather in Beijing, although does not help out activities, now is the best time of growth, the Lotus blooms. After June, will set off a tour of  Panasonic CGR-DU06 Battery Charger  Beijing Lotus boom in recent years more for photography lovers to join, make tours load more popular. The ancients: “reflecting our special Red of Lotus”, tour-Dutch, Dutch fun where exactly?
  • Which took on the Lotus?
  • Beijing’s many parks have a Lotus, mainly to zizhuyuan Park, Houhai, the Lotus pond Park, Summer Palace, Beijing Summer Palace and Botanical Garden, but due to the Lotus blooms around the time varying, therefore if you wanted to shoot, it is best to ask in advance.
  • Lotus shoot fun, even the hot sun can not stop. (Nikon 20mm side of D200+Tokina 12 – 24mm F4DX. Aperture, F/16, one-two hundred and fiftieth seconds shutter, ISO 200, Aperture priority, auto white balance, JPEG)
  •  
  • Shooting equipment required for Lotus
  • 1. camera: you can choose anti-noise in high ISO mode outstanding machines, so that in addition to JVC GR-D370U Battery Charger increasing the shutter speed can balance between picture quality; anti aircraft fuselage built better.
  • 2. lens: as Lotus pond area is quite large, more perfect Lotus Flower are often long in the Middle pool, so a telephoto zoom lens is almost essential, it would be anti shake function. If they want to take advantage of good weather shot with blue sky and white clouds in the background of the Lotus, or a convex mirror backup. But the Lotus Flower Pool is far more than, the Lotus is the only point-point spread, so cannot be taken out of the flowers in full bloom whose momentum, and when using a convex mirror, are difficult to avoid pedestrians and frame-in debris damage picture, on the composition of these problems are easy to make Lotus lost picture of subject, shooting had to pay attention.
  • 3. tripod: recommended single tripod, high mobility, if energy use shutter-, can reduce finger caused slight vibration when the shutter is pressed. Shooting shutter delay opening can be set to reduce airframe vibration caused by the mirror up, and make the picture more clear and sharp.
  • 4. fill tool: while filming when the Lotus is the use of natural light, but because Lotus was higher than the leaves, often only when the Sun has just come out glowing flowers, Lotus leaves are relatively dark a lot. When the composition, if you want to include some angles than bright blades, reflector and you fill flash will be an indispensable auxiliary tool.
  • Occasion of sunlight penetrating the Lotus and part of the Lotus leaf, is the best time of performance of light and  Panasonic Lumix DMC-TZ50 Battery Charger shadow. (Nikon D200+CZJ Sonnar3.5/135mm。 Aperture, F/4, one-four hundredth seconds shutter, ISO 100, Aperture priority, auto white balance, JPEG)
  • Weather decision metering techniques
  • 1. cloudy: whenever the weather encountered no sunlight, like a cloud in the sky, uniform light distribution of cases, this light conditions contrast that makes Lotus and Lotus leaves smaller, using matrix metering mode can take very good results. At this point, we can also adjust the contrast in the camera down, make the color more bland.
  • Cloudy with Lotus and Lotus Leaf light evenly, you can shoot a white and delicate feeling. (Nikon D200+Tamron 90mm F2.8。 Aperture, F/3.5, one-one thousand five hundredth seconds shutter, ISO 200, Aperture priority, auto white balance, JPEG)
  • 2. direct sunlight: when a fair weather that can best demonstrate the Lotus petal detail neat lines, as well as the soft beauty of permeability. At a time when the rising of the Sun, because Lotus was higher than the Lotus leaf, light only irradiation angle on the Lotus, often makes the contrast between the flowers and leaves large; in this case, we can use the spot metering on the petals metering, again depending on personal preference adjust the exposure compensation on light’s performance. Due to the impossible in reality only the bright lotus flowers, while the Lotus Leaf has a dark grey situation, so in order to increase the contrast, highlighting the beauty of the Lotus, we can adjust the contrast of the camera’s built-in high, or in the system after the contrast increase, the image would be more notable.
  • Under the Sun xiezhao, Lotus flowers and leaves of light and shadow contrast. (Nikon D200+ CZJ Sonnar 3.5/135mm。 Aperture, F/4, one-one thousand six hundredth seconds shutter, ISO 200, Aperture priority, auto white balance, JPEG)
  • Love Lotus have pictures of rights
  • Because Lotus has only three days of life, so the best Lotus Blossom soon can be found, most firm because its petals, flowers-the most perfect, most suitable for filming. However during the shooting process, not to individual shooting needs, spraying water on a Lotus leaf of Lotus because Lotus and Lotus Leaf leave black spot in the Sun, makes Lotus hurt, and was not free to move the location of the Lotus, or malicious damage them, after all, this is mother nature left us assets, must take care for them, we have to have been shot down.
  • Chuzhan of lotus flowers the most perfect, petals are relatively strong. (Nikon D200+CZJ Sonnar 3.5/135mm。 Aperture, F/5.6, one-six hundred and fortieth seconds shutter, ISO 200, Aperture priority, auto white balance, JPEG)
  • Up screen most of the Lotus leaf is not the protagonist, Petite white and delicate water lily is the eyes focus. (Nikon D200+SIGMA 20mm F1.8 20mm port. Aperture, F/5.6, one-one hundred and twenty fifth seconds shutter, ISO 100, Aperture priority, auto white balance, CPL, JPEG)
  • Summer moving Flower King
  • From June to July, is the best time to take the Lotus. In this long in two months time, as long as the hard shot, sure you will find “load your understanding” photo!
  • Lotus and Lotus leaves each corner of the composition, so that the overall picture is balanced. Nikon Coolpix S550 Battery Charger (Nikon D200+CZJ Sonnar 3.5/135mm。 F/5.6 aperture, shutter one-three hundred and fiftieth sec, ISO100, Aperture priority, auto white balance, JPEG)
  • Morning dew is dotted, Lotus and more look fresh and exciting, business is booming. (Nikon D200+SIGMA 70-300mm Macro APO 300mm port. Aperture, F/5.6, one-five hundredth seconds shutter, ISO 800, Aperture priority, auto white balance, JPEG)
