Will Prentice has a tutorial on how to set up lighting and the backdrop for pet photography. He is using a typical cloth 4 foot wide backdrop that is taped at the front so it lies flat. He is using strobe lights in a shoot through umbrella for the fill light and strobe lights in a silver lined soft box as the main light. He metered the fill light at F5.6 and the main light at F6.3. The combined light will meter at F8 in the center of the backdrop where the dog will be positioned. He is using the 70-200 lens on a Nikon camera. He suggested using F8 so you get adequate depth of field.
Some tips to photograph pets:
1- Take them for a walk before the shoot so they can go to the bathroom.
2- Use noise makers to get their attention.
3- It is best to photograph them immediately after a nap.
4- Be certain to have treats and toys handy to catch the pets attention.
