I'd like to consider myself a photographer and videographer all in the same vein. I enjoy both, and like to see how both can be cleaned up in post to create a nice final product. I must admit however that video sales are really trumping my image sales. Granted, I do have almost the same number of each (when usually one would have alot more photos when compared to videos, I would think).
My advice is that if your camera can shoot footage, definitely give it a whirl and begin learning the ropes... it is the future of sales, I am convinced.
Keep shooting and good luck in your sales, todays post was short short short.
