These are CGI images taken from a video I found on youtube.
During my Lucy Letters section paint flys across the screen. I was having trouble with the shape of the paint, completely bewildered of what flying liquid would look like. I studied the video a few times and took a couple of screenshots of the precise frames I wanted so I could carefully look at separate droplets.
This was an extreme help to me and I was pleased with the final outcome of my flying paint.
