I've been looking through a lot of my older digital photos lately and now that I am more confident in my post processing capabilities, I am having fun "fixing" them.
Take this photo of my kids for example. The white balance was set wrong so they look all purple. Not a great shot.
But with some color correction, cropping and creative editing, I was able to fix the colors and now it is one of my favorite pics of the kids. I wish they would look that happy together more often these days.
Old lousy photos are great to practice on when learning the ins and outs of post processing. It's also another reason why I rarely delete photo files. There is always some kind of hope that with a little work, it could still be an awesome shot.
