So I have been trying to get better and have things right in camera and not have to do any RAW tweaking. The problem is that from what I have read the d70s' histogram is only single channel (green). So while it might say everything is fine and not blown out in reality red and blue could be completely blown out. Since the d70s does not have all the channels in the histogram how can you tell if the image is blown? I have tried looking at the actual picture but really how much can you tell on the little LCD? Is there a general rule you can follow to preserve the colors? Like assume any one color won't be more then 1 stop more then another color nad just underexpose everything 1 stop and fix it with a level/curve adjustment in PS?
