Camera set-up
Pets are unpredictable at the best of times, so you'll need to set your camera up so you can work fast and react quickly. Here are our tips on how to set your camera up...
Just like people portraits, animals also benefit from a shallow depth-of-field to isolate them from their background. An 18-55mm kit lens that comes with a DSLR is great as a starting point, but these don't offer a fast maximum aperture of f/2.8 or faster that's needed blow the background out of focus significantly. The good news is that there's a selection of affordable prime lenses out there for a range of systems, including the excellent Nikon 35mm f/1.8G AF-S DX and Canon EF 50mm f/1.8 II.
For shallow depth-of-field portraits, set your camera to Aperture priority and open the lens up as wide as possible - ideally to f/1.8 if you're using one of the lenses above, but f/3.5-5.6 will do a reasonable job if you're using a 18-55mm kit lens.
