If you have a digital camera, the MAJORITY of the manufacturers provide a BASIC photo editing software. This can be used in many cases for editing your scans.
If you do a Google for "Free photo editing software" you find a multitude of listings, many of which are freeware or shareware (I have gotten some decent programs from shareware).
Hope this helps.
Campy,
Thanks for the cover. I hadn't even thought of that. I guess my brain is mush tonight. It's been a long day!!!
I think I have a couple of disks laying around here of the freebie version of that Photoshop gives out with digital cameras. If I can find it I'll check to make sure that it truly is free and I'll zip it up and send it to you if you want.
You can actually do quite a bit with an inkjet printer and the Avery media materials that are available. Not looking at the stars on the plane in these pictures, but all the rest of the graphics that I did here were done with an HP inkjet printer and Avery window decal material. It's a clear material that is easy to print on. One thing to keep in mind when doing graphics like these is that they aren't fuel proof. You need to seal them up in some way. When I did the SSE in these pictures I sealed them with clear monokote. But after a season of flying I wasn't happy with the way they were holding up. Since then I've found a better way of sealing graphics (all types including vinyl), use clear fingernail polish. It's easy to put on, it's crystal clear, it's fuel-proof, it dries hard as a rock, and it's very hard to see once it dries.
Hope this helps
