Close-Up Experiments

This summer I got a set of inexpensive close-up filters; basically they are small lenses that attach to the front of a lens and allow it to focus closer. I'd love to have a real macro lens but it's not in the budget right now, so these will have to do for now. Here are a couple of pictures I've taken while experimenting with these filters. There's an aspen leaf, a dried flower, and a pine tree.
