Wooo! After recommendation from my friend, I decided to buy a tripod and have a go at video painting progress, rather than photos.
This is just a tester video which is way too long (I haven't edited anything out) and shows little progress. It was just made for me to become familiar with iMovie and general video-editing.
I hope the final one won't be longer than 5 minutes and show the entire painting from start to finish with a scan at the end.
