Since everyone seemed to enjoy the last post, let’s play some more with doodles, scribbles, or anything else from your sketchbook. The tulip below was only a small sketch, so it was scanned at 600 ppi to make it bigger (300 ppi is usually enough resolution for images that will be printed.) The sketch was done in red pen for no particular reason (below left). First it was desaturated (Command>Shift>letter u on the Mac) to get rid of the color, then Levels was used to make the paper white and the lines black. For complete info about this process, please read Friday’s post.After the lines have been liberated from the background, all sorts of things are possible. You can start painting on an underlying layer (below left), fill the lines with another color and/or try different backgrounds (below center), or just go fun and funky (below right.) The rainbow effect was created with the Gradient tool with a preset gradient. The preset colors can always be altered after the gradient is applied. Don’t forget to lock the line layer with the ?/ key first, or the entire layer will get filled up.The character of the line is different depending on what you draw with. The shell below was drawn with a pencil originally, so the line is rougher. The difference would show up when printing on paper, but I’m not sure about fabric (since I haven’t printed on fabric much.)
