Using the free-hand drawing tool of TwoToJazz an image of Beethoven is colored using thin (low opacity) colors. The drawing was then Color Animated in TwoToJazz and snapshots of it were saved. A selection of the snapshots were used to create a collage (using PhotoGrid app), and then the gris was further processed using Waterlogue app. All images were then put together in a final grid.
Some useful tips:
Try coloring your image with thin (low opacity) grayish colors, using the free-hand drawing tool. When animated in TwoToJazz grayish colors (colors mixed with both white and black) generate many different colors. More pure colors in contrast generate colors that are more similar to the original color.
