I am continually learning new things with Photoshop and my job affords me opportunities to experiment. For instance, one of the staff wanted me to come up with a simple t-shirt design, in like, no time for a workshop we will have at school. The only thing I had to go on is that the theme is "cooperation" and that he wanted to see an illustration of the American Sign Language hand sign for that word. Not bad. I drew up the hands, inked them, fooled around with some text, and layed out a simple design. The only problem was that the hands looked pretty flat and that the linework of the the fingers and the creases in the palm was too busy to distiguish what is going on. That's when I thought of a recent blog that I periodically read. Chris Wahl, who is an amazing illustrator, posted a short tutorial on creating halftones using Photoshop. Mike Zeck also gives a great tutorial on his site. The effect that is created is like zip-a-tone sheets used by cartoonists not long ago.
