Here is how I took an image from photo to black and white line art. There are some extra steps, things I probably wouldn't do the same way again, but this shows how it was actually done. One of the ideas was to convert an image, and still have some human handwork in it.

The descriptions of many of the photos in this set tell some of the process:

Step 1: Start with a photo

Picture of start with a photo
Start with a photo. It is probably better if it has some decent contrast, but that can be fixed later.
Thank you sooo much for taking the time to do this step by step. you have no idea how much frustration you just saved me!!! I love you man.

Send me some photos of the work you do. This is a relatively new technique, and it would be nice to see it out in the wild.

Great Instructable. The pattern recognition engine in me sees a face in the fire. Was that intentional?
I can see the exact same thing in the real flame picture, that's pretty eerie.
This is a great demonstration of how hard-wired we are to recognize faces.

People are telling me they see faces when I wear the shirt, but that's coincidence. When I was making it, I was being kind of true to the lines I found and did not add editorial imagery to the picture. I did add some negative space to one line that I thought was a little wide for my taste, and a couple of repeating lines towards the top. You can see pretty much what I added by looking at the one with the blue pen. thanks
