Recently, I bought two 400W photographic lamps with gold cups. Camera d40. The clothing photo taken is red. White balance setting is useless? Is there any experience to teach?

Copy back the questions I answered in other forums before, hoping to help you.

AWB means automatic white balance. AWB can be handled in general, but in order to obtain more accurate color reproduction, strictly speaking, the camera's custom white balance should be used. Because the color temperature of light is different in different shooting environments and light, it will cause a certain degree of color deviation. Using custom white balance can basically overcome color deviation and ensure accurate color reproduction. The specific method is as follows: under the light of the shooting environment, use a standard gray card with reflectivity of 18% to shoot a photo, which requires accurate exposure and 100% to fill the picture. (Note: If you can't press the shutter because you can't focus automatically, please use MF to focus manually), and then select Custom White Balance in the white balance options menu of the camera. In the custom white balance menu, specify to use the gray card photo just taken, and press the SET key to set it. In this way, the color of the photos you take in this ambient light will be more accurate. But every time in a different light scene, you have to re-shoot the gray card and reset the file with a custom white balance. This method is generally used in occasions where commercial photography requires strict color reproduction. The method just mentioned is only applicable to Canon's digital SLR camera. Nikon's method is similar, but it also needs to take a gray card, but it doesn't need to be saved as a file. Please refer to the manual of the camera for specific operation, which is written in the manual.

(Note: Gray card is a kind of gray paper card with light reflectivity of 18%. At present, the best card sold in China should be Kodak's. A set of gray cards includes two 8* 10 large cards and a 5-inch small card. The price is around 150, which is about 50% cheaper for domestic products, but the reflectivity is not necessarily accurate. I suggest.

I wonder if I made myself clear.
