One thing I like to do when I am at the beach (and with my Dad's camera) is taking underwater pictures. I find it really fun, and the pictures either come out really cool (if you have long hair) or really funny looking. (bubbles coming out of your nose!)
Anyways here are some underwater pictures from this summer. If you're interested, you can find some of my past underwater pictures here, here, here and here. Also find more on flickr.
P.S. I thought they would look cooler with rainbow filters.
