Complex light, white balance strategy

In normal light looks white colors in darker light may seem not white, a fluorescent light "white" is also a "non-white". For all this if you can adjust Camera Batteries the white balance, in the photographs obtained can correctly to "white" as the base color to restore the other colors.
Generally white balance mode, taken to adapt to the different scenarios, such as: automatic white balance, tungsten light white balance, Lens Accessories fluorescent white balance, indoor white balance, manual adjustment.
Complex light, white balance strategy
Consideration of the white balance adjustment
Stage shooting (before), we have a lot of ways you can adjust Lighting Studio the "white balance", for example, from the camera to specify a specific white balance, custom white balance, and specify the color temperature.
After shooting, post-production stage, we can still image further adjustment, used several:
Use the color balance to adjust: If you know the images Camera Flash belong to bluish, reddish, greenish, yellowish ... etc. tendency can use this method.
2. Specify the color temperature to adjust: a single large block of light sources (such as natural light), the use of "specified color temperature adjustment is quite convenient approach.
3. Specify gray point adjustment: For more complex light sources (such as natural light + indoor certain light), you can specify the "gray point" approach to
Adjustment.
Gray dots
The gray point refers to the image in the middle tone, is usually Tripods Head a reflection rate of 18% of the area.
Gray dots specified Sometimes of course rely on skills, some photographers job, sometimes before taking a job, the first shooting an image contains a "gray card" or "white card", as a follow-up adjustment.
Browse below to make a way for the software specified gray dot.
Software applications
In PS curve tool, select the middle dropper to tap the Flash Accessories midtones of the image to image adjustment. As shown in Fig.
2 in the PI, "histogram" tool, select the middle dropper to go tap the midtones position of the left side of the image, for image adjustment. As shown in Fig.
3 in NX the white balance project, select "set gray point, Camera accessories  and then press the" start "button dropper to select Midtones position. (Which can be a single point of choice or a region)
Recently, I learned from dealers, the recent New a thousand Yuan pixels camera - NV10, currently priced at 3,599 yuan, now can get 1G SD card. The big advantage - price and performance as a DC in two main aspects, NV10 uses a traditional camera design ideas, that is, we usually understand the retro route. This will not only give consumers enjoy and appreciate the sensations, but also bring new ideas to the digital camera design. From NV10, retro models appearance will be DC's another hot series models.
The NV10 is still the retro route, the NV Series, the whole body are used frosted black material wrapped. The design of the handle is quite large, to ensure stability when shooting. This machine uses the ASR image stabilization system (electronic image stabilization), greatly enhance the card machine shooting space.
NV10 fast more advanced 1/1.8 inch CCD sensor, up to 10.1 million effective pixels, the highest output resolution still images of up to 3648X2736. The aircraft dynamic shooting ability with the NV7 compared the same outstanding Camera Equipment quality of the shooting reached mainstream 640X480/30fps. Lens selection, although the NV10 uses the same German Schneider lens, but the lens is no longer on the NV7 7.1X optical zoom design, but an ordinary 3X optical zoom lens. The lens 35mm camera equivalent focal length equivalent to 35-105mm, maximum aperture of F2.8-5.1, Closest focusing distance in macro mode is still 4cm.
The NV10 behind one with the NV7 the same high-quality LCD display (2.5 inches / 230 000 pixels), while it also has up to ISO1000 sensitivity level (the lowest ISO100). 15-1/2000 seconds shutter speed of the aircraft, and it also built-in 19MB memory space, and MMC / SD as the storage medium. NV10 source of electricity for SLB-0837 (B)-type lithium-ion battery capacity slightly to 800 mA, 180 photos camera tripod can be taken based on the CIPA standard. From the lens volume declined NV10 body thickness exceeded 2cm mark size of only 96.5X60X18.5mm, weight down to 148.7g. Equipped with a USB 2.0 interface, and through the interface of the camera for charging, use lithium batteries as a power source, use SD card storage media.
Personal view: In addition to the vintage look, the main feature of this NV10 is to have a 10 million-pixel CCD, although this is the second million pixel Photography Equipment digital camera, but the view retro plus 10 million pixel CCD, comprehensive evaluation is higher than the same as the 10 million pixel digital camera models S1000. In addition to the tens of millions of pixels, MPEG4 format video shooting, the other its 2.5-inch screen has a resolution of 230,000 pixels, is not lost on any mainstream card models. Need friends may wish to look at the market.
