I just downloaded a free photoshop type program called "Gimp 2". I took some photos that I had shot with my new camera in the pool and plugged them into this program. I simply went to the colors option. Then levels. Then hit Auto. I was amazed at how easy it was to really clean up the pics with this free program. I attached the before and after photos. I'm fairly new to photography in general so I don't know what you all will think, but I was quite impressed. Sorry the pictures are kinda boring. Some dive buddies invited me to the pool while they were teaching a class and I had to try out my new camera. Not much to look at in a pool so I shot the anchor since it had color.
