Last night I took a class in underwater Photgraphy. It was taught by the owners of Island Photographers of Cozumel.

Holly and Armando are amazing. They really know there stuff. We spent the first two hours learning about all of the settings of our camera and what the optimal settings for shooting pix underwater.
Until now, basically what I would do is take my camera underwater and shoot as many shots as I could. If I was lucky 1 or 2 would be decent.
What we then did last night was shoot pictures on a simulated reef in the pool at my local dive shop. I have downloaded the pix and will load them soon. Really looking forward to my next dive trip to try this out further!
