>>Paint shop pro may not offer all of the features you will need, you might want to look into photoshop elements, I think you can find it for about $50. Also if you get closer to the glass and clean it, it will help a ton. I wipe my glass down every day, and it makes it a lot better to take pictures through. Also taking a picture through condenstation will never produce a nice clear picture.
I think it turned out fairly good considering the circumstances. It was just before I did the daily maintenance, and I was worried that sticking my hand in the tank would disturb the frog from his pose. It's only a 1.2 megapixel camera, after all. Paint Shop Pro is a pretty beefy graphics editing program. It's not quite as good as full blown Photoshop, but at $100, it's about 1/5th the price. I'm sure it would have any elements that I need. Still, I think I have a copy of Photoshop Elements around here from when I bought my scanner. What tools would I need?
