Recently I was commissioned to draw stipple portrait of musician. Original photo was really great, professional, black and white with balanced contrast.
Usually I have to do some work to prepare the photo, sometimes it's a really solid task, and not only contrast tunning, it's just like a plastic surgery when you repair defects of the camera or objective distortions. But this time the photo was ready and I got so much pleasure drawing hedcut on it.
Here I decided mostly go with dots, maximally avoiding lines and crosshatching.
