Ask a photographer: How to adjust the red color of a photo?

When shooting, you can put a piece of white paper facing the camera under the light (flash) (it should be the standard Kodak gray board white paper as an alternative). Find the custom white balance on the camera menu and take a picture of white paper, indicating that the customization is successful.

Set it to white balance and you will get correct color reproduction.

The reasons are light (reflected light from environment), white balance of camera, lens of camera, photosensitive element of camera, software of camera (solid state), color difference of display, etc. And the color filter may also cause color difference.

High-end digital cameras usually support ADOBE RGB color gamut, which covers a wider range than SRGB color gamut. If a wide color gamut display is used, the colors of digital photos with ADOBE RGB color standards can be accurately displayed on the display. If you use an ordinary SRGB monitor, the color will probably be lighter. Professional graphic displays should be color corrected. With Starscream
