“It’s easy to become gear-obsessed with photography, but you don’t always need the best and biggest gear to capture a great shot.  I was in the Galapagos shooting for a client, and there were a few snorkel excursions where I couldn’t do any shooting for the client.  The only personal camera I brought was a Sony RX100, and I had a Nauticam housing and small light so that I could use it while snorkeling.  I came across a penguin resting at the surface who let me swim fairly close, and having spent hours underwater in the Falklands trying to capture a penguin underwater, I knew this was a unique opportunity.  To make sure the penguin was properly exposed while shooting up against the bright sky, I set my light to act as a fill.  Then, I held my breath and dove underwater, coming up below the penguin.  I could only take one shot since my strobe was slow to recycle, so I waited until the penguin filled the frame.  I managed to get three tries before the penguin swam away, and this was my favorite since he looked at me.  Sony RX100 at 28mm in a Nauticam housing with strobe.  f/6.3, 1/250 sec, ISO 125.”
