What it Takes to Lean to Do Computer Art
Mainly, what it takes to learn to do computer art, is plenty of patience, a relaxed but alert mind, and lots of time.
I’m sure you could pay somewhere for an intensive graphic arts course, but as I indicated above, all the software you need is available to you online for free. Just download and install them. Then try them out, and when you get stuck, go online to Google and research that particular problem or step you want to do. There are some good, some bad, videos on Youtube as well that show you step by step how to do various techniques.
That is how I’ve gradually taught myself over the last 15 or 16 years.
I have learned to really admire Vector Art, which looks like perfect sketches, but is all done on computer with a program like, InkScape, which is also free. I’ve explored it enough to know there are only about 5 or 6 basic shapes, and with those you can draw elegant swirls, roses, people, scenery, anything you would want.
My problem is that at present I can’t squeeze into my schedule the half hour or hour a day I’d like to work at that. I know that in a few months or a year, I’d be as good at it as any other professional, but of course, I would practice mostly in the themes I like best, flowers, and people.
Look for the free software programs, (available to Windows as well as Linux), like GIMP, InkScape, ImageMagick, etc. If you have the time and patience, you can teach yourself how to do this.
