Why were all my layers merged into one when saving PSD file?
Help! I had at least a dozen layers in progress when I saved the file at the end of the day's work yesterday. I saved it as a PSD file, just as I always do. But when I opened it this morning, all it has is one background layer with all my work merged together!! 1) Is there any way to get my layers back? 2) what could I have done to cause this to happen?
