I think we have all been there. You make a piece of art, it's 3am and you hit the save as a psd button to work on it later.
Sadly sometimes we flatten the image first and only have 1 lousy layer for our PSD.
I did that with the image below. I was hoping to work on it later. Now I have a flattened image that I can't work on. I can't unflatten it. When I opened the .psd file there was only the one layer. My, "Oh, No, No, No' echoed through the building. I wanted to cry.
I googled, Unflatten image in photoshop and found page after page of people pleading for help. Why does photoshop do this? I even checked the Adobe site. It was basically, Sorry sucka.
There is one tip I have to offer. When saving, look to the bottom left of the save screen. There is a box that asks, save as a copy? Check that box. Apparently it will save the original .psd.
