i sectionalized a photo of my self into geometric shapes. then i hand cut different cores of paper and rubber cemented them on a black to ablack background. it was very difficult and it took forever but was defentl worth it.
Yes, it's not easy to do, but it's a very good and interesting work. It's interesting to understand the volume, shades and lights with just a few pieces of paper...great I've done it when i was student and it help me a lot now for my painting.
