The idea is you have a picture of a face (or any image) and you want to cut it into metal or wood using a CNC tool or paint it on something or carve it into something.
You need some way to turn this really complex picture into a collection of simple shapes without losing the ESSENCE of it.
This time, I want to demonstrate a trick that involves GIMP. GIMP is a free paint program (GNU Image Manipulation Program). Find it here: http://www.gimp.org/ GIMP has a filter that I couldn't find in Photoshop that's kind of cheesy in just the way I need it be.
This time, I'm going to actually cut it out of something just to demonstrate that you can actually do that. The first image on this intro is a piece of 14"x14" matte board laser cut with the image described and then held up against a blue wall.
I made it at Techshop! www.techshop.ws
Step 1: Open Your Image In GIMP
Run GIMP and then open your original photo in it.
Step 2: Focus On The Part You Want
This is an artistic choice, allowing you to focus on the most important part of your picture. Mostly though it's practical; if you do this now, you can focus all your work on something that fits on the screen.
Use image->autocrop to select just the image and cut out the white space. Then use image->scale image to make it larger -- 2000 in it's smallest dimension should be good.
Step 3: Grayscale
It's still a breathtakingly beautiful and complicated image.
