Cam­era skills set up your Cam­era

Pre­pare your Dslr for un­der­wa­ter ac­tion with these es­sen­tial skills

01 try back-but­ton fo­cus­ing

Half-press­ing the shut­ter but­ton to en­gage aut­o­fo­cus can be rather tricky through the bag. So in­stead – if your cam­era al­lows it – try set­ting up back-but­ton fo­cus­ing. With this op­tion en­abled, fo­cus is ac­ti­vated with the AF but­ton on the rear of the cam­era body.

02 set a wide fo­cal length

As you can see in the body below the sur­face here, the wa­ter has a mag­ni­fy­ing ef­fect. As such, it’s best to use a wide-an­gle lens, or the wide end of a stan­dard zoom lens. Fram­ing can be tricky un­der­wa­ter, so a wide an­gle also gives you the op­tion to crop later.

03 use a nar­row aper­ture

Fo­cus­ing can be less than pre­cise when shoot­ing un­der­wa­ter – espe­cially if your sub­ject is mov­ing to­wards you – so it’s best to use a nar­row aper­ture as this will give you greater depth of field, mean­ing more of your sub­ject and scene are in-fo­cus.

04 Pre­vent mo­tion blur

You’ll need a fast shut­ter speed to freeze the ac­tion, espe­cially if you plan on cap­tur­ing jumps and splashes. We used 1/500 sec. Our DSLR was set to Man­ual with Auto ISO on, so the ISO adapts to suit the con­di­tions. At an f/11, ISO ranged from 100-400.
