How to create coloring book pages from photos
I'm trying to create coloring book pages from photos. There seems to be a general technique online where a photo is copied, inverted, desaturated with a mode set to color dodge, then a Gaussian blur is applied. I've seen other techniques just by applying a sketch or photocopy filter.
I'm looking for a more advanced technique to generate better results. Can anyone point me in the right direction?
