This great white shark photo (Carcharodon carcharias) was shot under dark skies, in early morning. These are tough conditions to shoot underwater with only available light. I prefer to shoot without strobes whenever possible but in the days of film this particular morning would have required I use artificial lights. Digital cameras, however, have changed all that and allow shooting in dark and flat lighting conditions that film did not. I hope to get back down to Guadalupe Island later this year to reshoot these sharks with the current cameras I am using (5D Mark III and D800). I think I have made 15 trips to the island (I’ve lost count) and I never get tired of Isla Guadalupe. Cheers and thanks for looking!
