For anyone looking for a prompt to do this manually, it seems to be as simple as this:

> Generate a version of this photo that can be used as a coloring sheet

Close enough! The prompt I use is:

> Make this a page in a colouring book. The drawing is in a simple Studio Ghibli portrait style. Bleed all the way to the edges. Background colour is #ffffff and lines are bold and #000000. There is no shading or crossthatching.

Anyone else feeling this weird vibe in the age of AI? You get a cool new idea, but then you think about how easy it is for someone else to replicate it, and you end up not doing it.

The OP looks like it runs images through a Ghibli filter first

Yeah I've been doing this with image-gen AIs pretty much since they started and it's a lot of fun. Even early Dall-E etc was awesome at doing stuff like "Create a colouring in sheet with some dinosaurs having a party" or generic prompts like that, and more recently giving photos to convert has been loads of fun for the kids.

I’ve done this a bunch with my son. It’s not quite that simple because often times it’ll create images that have too much detail, sometimes it’ll actually include colors. But yeah, it’s not really all that complicated
