Simply superb dive images by Jan Messersmith – there's Lionfish, Clark’s Anemonefish (Amphiprion clarkii) and Bulb Anemone. He's also posted his opinions about the image quality of the camera.
Jan used the WP-DC28 waterproof case to get the G10 underwater, and added:
I’m really happy with my new rig. People pay thousands of dollars for underwater cameras that don’t produce images any better than these. The difference is that the extra money buys you mostly more light on the subject. If you are willing to stay within the confines of available light and limit yourself to close shots when using flash, you can take professional quality underwater photos for way under a thousand US$. The G10 costs about US$400 and the housing was, I think, less than $200.
