Hi Gang............. I did a few tests with my Olympus E-10 using both the built in flash and my Studio Lights (White Lightning 5000's) I used the auto white balance . I took shots around the house using the built in flash in some cases using the self timer to taking some shots of myself. In the studio a friend sat in front of a mottled brown backdrop and wore a red Polo shirt. On my computer monitor the color on the shots I took around the house appears perfect. On the Studio shots there is a large amount of magenta(pink/red) in the photo. As I correct for this in the printer to create a profile for the paper I am using I end up getting an alright skin tone but the back drop color shifts towards the green. (I am trying to create a profile so I am not adjusting the image color in PS) I wonder if the white balance was affected by the red shirt or maybe I should manually set the white balance for the Studio Lights rather than use auto.
