This was an experiment. Rather than waste a whole bunch of lead or black ink trying to draw outer space, I decided to draw it in negative, then invert it on the computer.
First, I scanned it in and flipped the colors. Then, since I scratched it out in the middle of the night last night by the dull glow of a computer monitor and so the transitions weren’t anywhere near as smooth as I’d like, I threw a slight blur on it.
After that, it was simply a matter of cropping it and using a noise filter to randomly generate the star field in the background.
I think this idea shows some promise, and I’m definitely going to try again, but some time when I have the time to sit down and get the shading smooth.
