Onslow - Thank you for the information. I did shoot the images in raw format, taking them into Photoshop to set the white balance. I did try most of the white balance settings on the camera, but none of them looked like a perfect picture. Once I was in Phtotoshop, I used the curve adjustment tool to select the white in the Gi's and also the white edges of the mat. But as you can see from the two images they produce different results based on the location inside the gym. I will try the grey dropper tonight when I get home. Every time I see those lights I just cringe now. :- Thanks Vince
