Underwater Photography on the Cheap

In the prior installment of the Macworld Video, Chris Breen offered up a number of suggestions on how to share your movies and photos with friends. Working backwards, as I often do, I thought I'd offer up some suggestions on how to get your images ready for sharing.
But not just any images--underwater images in particular.
That's right; this week's focus is on underwater images--a bit of a primer on how to get into underwater photography on the cheap (because that's the only way I can do it!).
And finally I'll also demonstration some simple editing techniques in iPhoto to make those underwater pictures look their best.

Show Notes
In the course of the video, I discuss my underwater setup, which consists of a Canon PowerShot SD850 IS and a Canon WP-DC15 waterproof case. I bought the camera as a factory refurb on eBay, and I found the case for much less than Canon's suggested retail on Amazon.
I also mention my Bonaire Underwater image gallery, which contains the nine images shown in this week's video।
