very good idea. I didn't know you could upload your own pictures to picasa web. I will make a web space to upload underwater pics, but that may take a while, because next dive will be without camera, just the housing. As octopus said, I will experiment with this setup (without wide-angle, without red filter) for a while, and then see what I want to do... buy an external flash, or a wide-angle lens etc. The editing with the picasa is interesting. Unfortunately my camera does not support RAW, which is the best option to edit.
In one book I am reading on U/W photography, two important rules are:
1.get closer to subject and 2. shoot upwards (Edge's book). I will keep you posted re: uploading.
