If you do not already have a favourite photograph for me to create a pastel portrait of your pet, here are some tips for you to get some good shots of your horse dog or cat for me to paint from.
Phone cameras are so good these days you should be able to get some great shots yourself. When I first started painting pet portraits we didn't have phone cameras. So locally I would go out with my camera and take pictures of client's horses, dogs and cats and get the films developed, it was a long winded process! It was made a bit easier with the advent of digital cameras, I still have mine – a Canon EOS with long zoom lens which was great because I could stand well back and zoom in on the subject and get a great blurred background.

To photograph horses you may need a helper (or
