3. Using Krita as a free alternative
I'm not an expert in Krita, but I have used it for background painting in the past. The biggest benefit of Krita is that it is FREE! And that makes it a pretty good introduction software for certain people. There has already been a very good video made on how to use Krita for animation, so I'm going to let kdsketch take over this lesson.
You can download Krita for free HERE
The other benefit of Krita is that you can load up image sequences in there, which means you can basically load up my source files. This should be helpful to you when you are following along the later animation exercises, if you don't have either Adobe Animate or TVPaint.
