I'm a temporary host for two cats that live in my attic, separated from my own cat who lives downstairs. One of my temporary companions lays herself down on my keyboard when I'm upstairs, making it impossible to work on my regular computer. So I am working on the machine in the livingroom that has modest specs. I downloaded the open source program Gimp that I've never used before and try to see if it's an option that works as well as Corel PhotoPaint that I use to make digital portraits.
The learning curve isn't very steep, but it takes some time to turn out a quality similar to that which is possible with PhotoPaint. The latter (2017 version) has a lot user friendly options that speed up working that aren't available in Gimp or perhaps that I just haven't yet discovered them. Besides, Gimp is free, so what the developers have achieved is more than excellent. Below you see the sequence of a portrait of Mark Twain; the oldest stage at the bottom, the newest on top. I forgot the record the first stages and started when I made some progress already.
Gimp is somewhat more coarse than Corel PhotoPaint and lacks on canvas controls (which speed up working significantly), but hey... it's free. I should have defined the resolution before starting to draw, but due to being unfamiliar with this program I forgot. The image size should have been larger as well to make sure prints would have the desired quality.
Tip for desktop users: Click on one of the images which will bring you to Blogger's Lightbox that allows you to scroll through the different stages, allowing you to see the difference between the stages faster and more clearly.
