Excuse me, why are the photos of shoes taken by both cameras red?

Color temperature: white balance setting. If your white balance setting is wrong and the color temperature is too high, some red will appear.

When turning on the light, it is generally adjusted to the white balance of incandescent lamp or white fluorescent lamp, and the color temperature is adjusted below 5000.

Contrast: Sometimes the contrast is too high, which can also lead to red color.

Packet inspection: saturation also has some influence on this.

It is recommended to use the RAW format, so that you will have enough room to modify later, and many things can be modified. In this case, even if the original film is red, it can be processed to a normal level.
