@Curator Oh? So THIS is what my friend does! Saw him sketch with a red pencil a while ago but never thought about asking why he's doing that. So far I've been using normal pencils and erasing them after the lineart is done, but I usually just end up with crinkled paper and smudged lines. 🙈 Will look into these, thanks for the heads-up!
@bestiaexmachina Yeah! IN theory you can use any colour that's not black, then you can selectively remove the colour after scanning, in whatever software you use to touch up, like Krita or Photoshop or whatever. But yes there are also pencils you can get that are invisible to scanners :O
@Ozzzylot @Curator @bestiaexmachina Stuff I learned in art school twenty something years ago... There's a history of the particular color blue used in graph paper, and some lined notebook paper. It get called non-repro, or non-photo blue. Photocopiers have always been programed to not pick up that color. But before Xerox there was a particular film used in the copy cameras in the print industry that did not pick up that color.
honestly this even works with gray lines (or gray dots?) if you can use a dark ink before photographing/scanning. you just put your black/white threshold between the brightness of the gray you want to eliminate and the black of the ink you would like to keep.
blue makes it easier though
@edyother @Ozzzylot @Curator @bestiaexmachina This is precisely why I still do all my under sketching in blue when I’m working with digital, I got in the habit of using blue under sketching through training to do narrative and sequential work (comics) before and during my first go at university. I don’t do it with trad media anymore, unless I’m mucking about in a sketchbook rather than working on something I want to finish :)
@bestiaexmachina Another benefit is that it's easier to see the lines without the sketch getting in the way - I draw digitally but I like to color my sketch a pale blue so I can clearly see the shapes I'm making
