I have all kinds of nice camera stuff, but I have no idea how to use it underwater. I have a couple of Canon 5ds, a whole pile of L lenses (including 100mm macro, 24-70 and many more), avast portal, etc. There is no reason that I cannot take good photos. I am willing to trade acropora frags if somebody can come over and show me how to use it. I also have a iMac for processing.
