>>6209716>Light bounce seems to be causing issues with making the white's look yellow.Yup, the bulbs I use are yellow light, and the walls of the room I shoot in are cream colored (plus the brown shades, wood fixtures, doors, etc) all contribute.
Luckily, the Auto-Tone and Auto-Color tools, or the Levels adjustment tool, can usually take care of the yellow tint.
In this case, I just used the Levels eyedropper for white and picked a spot on the left corner of the baseplate, and it autocorrected that spot as "white" and changed the color of the image to match (which meant that any surface that was that tint or lighter became white).
My camera has different lighting modes for different conditions (different bulb types like tungsten, different outdoor conditions, etc.). Those can also be used to cancel out the adverse effects of non-white bounce light.
