Okay, so we’ve all had it once that we scanned something in and wanted to make it transparent. LIke, removing the white from a lineart on white paper. For this you can set the layer on multiply or even use masking techniques.
In my case, I’m doing a water-coloured webcomic, and I wanted to remove the white, without damaging the colours. So that I could overlap the picture onto another and the colours would blend.
I was before messing around with masking techniques, but I had problem with keeping the colours right. I’ve now found a technique that’s a bit more easy, and which allows me to draw this:
What you need:
*A picture(scanned in or otherwise)
*A computer with the gimp installed.
My version of the gimp is Dutch, so I’ll be putting the english name of the steps in bold.
