I have no Idea how many people know this but its a life saver

Start off with a crappy scanned/phone taken picture like so

Mess around with the SAI Filters, I usually go color deepen all the way to the left then mess with brightness and contrast until I find a good balance I like, then to top it off with a copied layer on multiply to make the lines darker
Click what I boxed off and the magic has already happened
you now are left with a clean lineart layer that you can color underneath to your liking : 0 Hell you can even color your lines however you want as well for a colored lineart

ok i wasn’t going to reblog this first but honestly this is such a life/time saver. you can get a neat lineart in minutes instead of using a hour (or more) on ‘copying’ the lineart digitally. share this as much as you can. especially since it’s on sai which is what most aspiring artists on this site use…
