With people it seems easier to push the threshold in Photoshop to make pop style portraits, but it's just not the same with animals. It's amazing how much distortion the human face can take and still be recognizable. Today I played with my niece's baby, Buttercup, and decided to try a little mix of halftoning and high threshold with coloring, but just on spots, like her little tummy, tongue and ears. Even then I kept it overlaid and at a reduced percentage so that the original photo was evident. It's more difficult still when so much of the animal is dark like Buttercup. At least with her posing in her reclining position all of her white spots were showing. I think I'll be trying this combination with more of the animal portraits I work on; real photo, pop and halftone.
