Choosing a Camera for Reference Photos

My dog tore up my camera. Sigh. So, recently I have been shopping for a new camera.

When I started painting, I always worked from life. A couple of years ago I realized that working from life, although it is a great way to work, severely restricted the types of poses I could paint.

I decided it was time to learn more about exactly how the sun tracks across the sky.
