Our latest assignment for Katherine Streeter was a open-ended celebrity portrait. I chose a straightforward representation of Buster Keaton.
This project also taught me a new photoshop trick for eliminating those awful stepped gradients without resorting to imports from illustrator. Simply applied the "Add Noise" filter to the gradient layer. The example above is intentionally grainy, but as long as you keep the noise level low, you can get a very smooth finish.
