I did 3 wrecks and the canyon over 2 days. This was shot using a GoPro with the dive housing and a red filter. It's my first attempt at underwater videography, so forgive me for the crude footage. Looks like in the low light the filter made all the red stuff pinkish. It's a bit long, sorry, but the best footage is at the end. It was a weekend of great diving in San Diego!
