I need to shoot some products that have colored LEDs. They will be emitting a nice glow, and my thoughts are that I want to capture a shot that is totally illuminated only with the products light. I guess at best I could equate it to a camping light. But I realized I have no idea how to shoot this for accurate color. I would rather not leave it on auto WB and spend forever tweaking to taste in post if there is a way I can use my Color Checker to do this, but I only know how to correct for color casts, not accurately capture them.
