For this tight por­trait of a crocodile bask­ing in the sun [above], I took Lou’s ad­vice about set­ting a high ISO, and used it to get the depth of field I needed. I set an aper­ture of f/11 in aper­ture-pri­or­ity mode to en­sure there would be enough depth of field to get the crocodile as sharp as pos­si­ble from front to back. I also di­aled in a stop of neg­a­tive ex­po­sure com­pen­sa­tion, as oth­er­wise the dark back­ground would have been ren­dered as an av­er­age mid­tone, and the high­lights in the croc would have started to blow out. At ISO800 this gave me a shut­ter speed of 1/1000 sec – not quite as fast as I’d have liked on Lou’s 600mm f/4, but I didn’t want to push the ISO any higher – and thanks to the gim­bal heads mounted on Lou’s boat, it was just about fast enough [see Killer Kit #02 and #03, and page 124 for more on gim­bal heads]. I love the way the strong side-light­ing brings out the tex­ture of the croc’s skin, and helps lift it off the darker back­ground.
