My Keyboard My Hands

Step 2 Process the image

Next comes the image processing. I opened one of the images of my hands on the white paper background in Photoshop. Using the magic wand, the selector tool and the eraser tool I went in and got rid of everything but my hands. This takes some time (what with the detail of my hairy wrists and all) but it was definitely worth it in order to get a nice clean trace.

Then, I placed the image of my computer keyboard on a new layer and positioned my hands in place over the home row of keys. They were already in the correct general location from the dots on the white paper, but they needed just a little tweaking to be be perfectly aligned.

I desaturated the image (lasers only print grayscale images) and turned up the brightness and the contrast a bit so that my hands really popped.

The last part of the image processing was to resize the image. I measured the distance between two points on my laptop in real life and then resized the image in Photoshop to match that same distance on the screen.
