Photoshop is a great tool to use on photographs as most of you know but it also saves them too.
I uploaded my pictures from my cruise and low and behold 
found a picture in which I blinked (didn't realize it at the time when I saw it in the viewer, which is an important tip, always look & zoom more closely at photos in the viewer of your digital camera).
Well no need to worry with photoshop I cleared up that problem easily.........
it helped too that I was already wearing glasses so that made it easy too.
So remember next time you think you have a bad photo and going to delete it don't do it fix it with photoshop, and if you can't send it to me and I'll fix it for you and give you a good deal!!
