Hence the: "Creating a custom WB is a great way to go provided that your RAW converter can actually utilize it." Not all raw converters could/can utilize the custom WB data created by doing this. Some would just toss it out and use some default value instead. Most converters can now correctly support that functionality. I do it (use custom WB) all the time myself. I have been known to stick a piece of white toilet tissue between two Qflash diffusers and use that to do custom white balances. It works surprisingly well. My comment about the gretag was to illustrate an alternate approach. Lawrence ----------------------------- Lawrence Smith Photography http://www.lwsphoto.com -----------------------------
