Nikon d5 100 uses a flash studio, and the photos taken are red. Please seek help.

1, correctly understand funny sentences such as white balance, original white paper and white wall. 2. Understand the color temperature. For example, if your picture is red, then reduce the color temperature or color balance to blue. 3. Understand the studio, the lighting of various subjects is different, the metal should reflect the texture, and the metal is totally reflective, and CPL cannot be eliminated, so the incident angle should be adjusted. 4. Either the master or 2B uses the M file! Aperture priority, turn off anti-shake, and turn on TTL if it blinks.
