Here is one of my recent hand-drawn frame-by-frame animations:
This one started out by just letting lines play. One frame would suggest the next drawing or two and sometimes it would spark my imagination to complete a whole sequence of drawings. About half way through I knew what was going to happen so I just drew it until it was finished.
The really fun part was diving into the thousands of sound samples I have created and collected over the years to add another dimension to the animation.
In the near future, I will be posting more of my recent experiments and learning experiences with tradigital animation. It is baby steps for me at this time, but each animation I complete makes me want to do another and to learn more techniques and to improve my facility with the software I am using: Toon Boom Animate Pro 2.
