I found it surprising that with few months passed by in this thread, no one have came to mention the art program I'm regularly using yet. It's relatively known in libre software scene, but it's not usually heard of in the art circle outside. So now, it's my turn...
Most digital illustrations I have been making in the last decade, are made as SVG vector graphics under
Inkscape (1), which is
libre software. My drawing hardware being a run-off-the-mill wired optical mouse was one of the reasons that led me to choose vector graphics and Inkscape in the beginning.
- In retrospect, my decision to choose libre software over proprietary Adobe Illustrator early on (2)(3) has proven to be the best decision I have ever made in my artistic journey; considering that Adobe "creative clown" abominations are now available only for lease, require Internet, and feed you to art-laundering machines' chop-shop by default.
- And this is also one of the reasons that I could gradually, nonchalantly, and completely phase out my Microsoft Windows usage over the years: a process which I completed just before the end of 2010s; so I have never needed to inflict myself with a spyware-disguised-as-an-OS named Windows 10 (or Windows 11, for that matter).
- Another bonus point is SVG --a vector format that Inkscape uses natively-- is a long-standing libre web standard that's now widely-adopted; meaning things I saved from Inkscape can be viewed directly on modern and off-modern web browser that everybody have. No such luck with EPS-based `*.ai` files you saved from Adobe Illustrator!
Other than that, at some point in the past,
I also wrote my own software so I could sketch things (B/W raster) on my not-Android not-iOS resistive-touch PDA phone at my leisure; but I no longer use that now, because my PDA phone stopped working several years ago.
P.S. I also used to do pixel art with Microsoft Paint 4.x/5.x back in my Windows days. I wished that I could use GNU GIMP for that, but it doesn't have drawing tools suitable for it. In my view, GIMP is only usable for digital raster art task
if one has a graphics tablet and use brush tool like a painter. KDE KolourPaint (and to less extent, mtPaint) is a more proper analog of Microsoft Paint, but I have not seriously explored its use for pixel artwork yet.
Don't get me wrong, I still use GNU GIMP on semi-regular basis; but only for photo and general image editing. As already said, It is rather Inkscape that I actually use for drawing.
(1) And since I'm also oldschool, I use tested-and-true version 0.48. (While I run GNU/Linux pretty much exclusively nowadays, I will note here that Inkscape version
before 1.x also works on Windows version as early as XP)
(2) Done purely for
Stallman reasons; as I have already known about libre software scene, and have been using GNU/Linux as a side OS for several years at that point. (My first few months with Inkscape were even done exclusively under GNU/Linux bootup as well)
(3) Back at the time before I started teaching myself to draw digitally, one of my feet had already been dragged into the quicksand of Adobe's empire by my educational institution (read: high school), because they taught Adobe Photoshop and Macromedia/Adobe Flash. Teaching kids to use proprietary software is like teaching them to smoke-- fostering dependency on a specific product that deteriorate their digital rights, personal autonomy, and social unity at large.
