Well, I have Photoshop (CS3 Extended) and use it regularly so I don't really need to learn GIMP. GIMP came installed on my wife's new computer, so I had a look. If I didn't have so much time invested in learning Photoshop (no training, just a LOT of time spent looking around), I would probably learn GIMP. Same with OpenOffice vs.
MS Office. I started using Excel in 1987; in fact that (plus Aldous - now Adobe - Pagemaker) is why I started using Windows at about that time (no DOS versions of either program). Too much trouble to learn new programs now.
Besides the usual cropping, adjusting colors and levels, etc., this is the sort of thing I do with Photoshop:http://i898.photobuc...nburghfix-1.jpg
This is the before and after of a badly damaged (looks like it was stepped on while lying on a bed of gravel, or maybe a dog chewed on it) photograph of my grandmother in 1937. It represents about 20 hours of repair work. This was my second or third effort at photo repair. I'm a bit faster now. And I don't make mistakes like the elbow of her coat so much. BTW, I'm willing to make repairs like this for friends, and I would certainly consider fellow rev flyers to be friends.
I made my Rev icon with Photoshop, but I reduced the palette too much and it looks a bit dull. I need to start over (from a photo of my old Rev I) and brighten, rather than dull, the colors. To compete with the standard Google icons it really needs to "pop" with a bright yellow and a bright blue. Maybe Posterize it to flatten the colors and then replace with pure web colors like #0066ff and #ffff00.
To get the transparent background I cut out the kite to a new transparent layer and then deleted the background layer. I adjusted the rotation and location of the kite so that the point of the left leading edge was at the center of the bottom edge of the picture. This let the "point" be equivalent to the point of the standard icons (the active point where Google "thinks" the icon is located). If I flew only Eddy kites it would be so simple; nice little diamond with the point right where it should be.
