Here are some thoughts on how to get the best reference photo of your furry friend:
Take your picture outside or at the very least next to a window. Natural light really is the best when it comes to illuminating a subject. It’s hard to see detail when the subject is lit with artificial light. Indoor lighting doesn’t provide contrast and clarity to the same degree as natural light. Some of the most interesting photographs to work from show an animal that is partially illuminated in sunlight and partially in shadow. Scroll down to see some examples of well lit and poorly lit photos.
If you really want to capture an amazing shot, take your picture during the golden hour. This occurs an hour after sunrise or an hour before sunset. Try for a day with a clear sky with little to no clouds. See if you can get your pet in a place where there is direct sun or where light is coming through something like trees. Take a look at the picture of Opie to see an example of a photo with good lighting. Also, the picture of Addie in the woods shows light filtering through trees, which would make for an interesting piece.
