In the Dark with Ham­mer­head Sharks

Asian Diver (English) - - Editor’s Note - By Ace Wu

For the un­der­wa­ter pho­tog­ra­pher, a cam­era with an ul­tra-high­res­o­lu­tion sen­sor like the Canon EOS 5DS R can be an in­valu­able tool when fac­ing chal­leng­ing marine sub­jects. Some­times, div­ing con­di­tions pre­vent us from get­ting close to the sub­ject. In other cases, the an­i­mal might sim­ply be wary of us, so we are forced to keep our dis­tance. To get the shot, we need to be cre­ative, and work fast and pre­cisely.

On my re­cent trip to the Red Sea in Egypt, I was for­tu­nate to be able to cap­ture im­pres­sive im­ages by mak­ing use of the ex­cep­tional per­for­mance of the EOS 5DS R. Due to the unique marine en­vi­ron­ment of Daedalus Reef, ham­mer­head sharks are often found in large schools. How­ever, on the first day, there wasn’t a ham­mer­head in sight, even as deep as 35 me­tres. I de­cided to change my strat­egy.

The fol­low­ing day, I reached the site be­fore the other dive boats ar­rived, hop­ing to get the first shots of the day. At 39 me­tres, the pitch-black wa­ter must have been wel­com­ing to the sharks, as it didn’t take long for a school of ham­mer­heads to swim by, with a few friendly in­di­vid­u­als com­ing al­most within shoot­ing dis­tance.

Although I was fur­ther from the sharks than I would have liked, the EOS 5DS R’s 50.6-megapixel sen­sor pro­vided a way to com­pen­sate for the in­creased dis­tance. The low-light con­di­tions pre­sented no dif­fi­culty for the EOS 5DS R, thanks to its light­ning-fast 61-point aut­o­fo­cus sys­tem, which al­lowed me to achieve ac­cu­rate fo­cus on the sub­ject.

In ad­di­tion to the in­cred­i­bly high pixel fea­ture, the crop fea­ture al­lowed me to in­stantly ex­tend my lens fo­cal length by up to 1.6 times while still re­tain­ing enough pix­els to pro­duce large prints. It’s al­ways frus­trat­ing when im­ages turn out blur, but now that I’ve tried and tested the EOS 5DS R, I be­lieve that it is the un­der­wa­ter pho­tog­ra­pher’s se­cret to amaz­ing im­ages!
