Reducing Portrait to Basic Colors and Lines - ev1lchris - 02-22-2018 Hi everyone, I'm relatively new to Gimp after being an Adobe Photoshop user. I was wondering how I could go about taking a portrait and reducing it to it's basic colors and lines? I want it to look like it was drawn or maybe etched. RE: Reducing Portrait to Basic Colors and Lines - rich2005 - 02-22-2018 There is a standard Gimp filter in Filters -> Artistic -> Cartoon but it has been there a long time, there are better versions. You could try the g'mic plugin http://www.gmic.eu which contains all sorts of effects. If you try it, read the instructions for a Windows install. You need to set up the correct path in Edit -> Preferences but one effect looks like this edit: A quick look around and an interesting procedure from Pat Davids blog. https://patdavid.net/2014/09/woodcuthedcutish-effect.html It requires using a gmic filter, but nice resulting effect. RE: Reducing Portrait to Basic Colors and Lines - Espermaschine - 02-22-2018 A bunch of scripts on this blog, which has some nice basic effects (copy the code and save as *.scm into your scripts-folder): http://joe1gk.blogspot.de/ I wrote a tutorial, that involves a lot of techniques rolled into one effect: http://gimp-science-labs.blogspot.de/2015/03/posterized-stencil-inspired-tutorial.html At the core you will probably need a way to reduce colours, with tools like Posterize, Indexed Mode, or filters like Quantize, combined with some edge detect for the lines (Artistic -> Photocopy is another option). Seems like David has improved the G'MIC - Posterize. Nice ! [attachment=1478]
