Ok, first of all, real new to PS CS2. I also know, RTFM. Now, after switching to LAB, making a copy of the original, switching to LUMINOSITY, then applying Unsharp Mask, I am ready to switch back to RGB. Switching back to RGB, it says that all layer information will be lost, flatten, or cancel. Do I just flatten the image? And is the Unsharp Mask still intack? Or if someone has a workflow I could follow for this, it would help me. Thank you, George.
