Graphic software for decals

Personally, I use an old copy of PaintShopPro 5 (which is not free), and has now been bought by Corel, and updated to version 13 or later. It's hard to teach an old dog new tricks, and I like the way PSP5 works, and prefer it to some of the packages with fancier features.

Another good (and free) editor is GIMP: www.gimp.org It's a good basic editor, and has several features like the commercial packages such as Adobe Photo Shop.

DrPic is an online editor that is pretty functional www.drpic.com/

All of these packages require that you get in and learn their quirks. To become a master of any of them is going to take some time.

Also.. on resizing pictures.. there are a couple of tips. Fortunately, you're going down in size.. scaling UP is much more trouble.

1) Learn what "AntiAlias" means, and how to do it.. that's the clue to making believable, recognizable images.

2) When shrinking an image, I suggest doing it in steps, not one single step. If you have say an HO decal, then don't immediately drop it to 30%, but go in steps like 75% then 75% then 75% then 75%.. giving you a net of 31%, but it often retains more of the recognizable info than going straight down to 30%. You may need to do cleanup of the image at each of these steps.. GOOD images take some work.
