Yeah, all the black ones used the "lights-out" method, but in a dark room during the day. The light background ones are with the lid closed, the others with it open. You get a lot better images with the scanner open!

I have 206 images I have scanned, about 50/50 on white or black background of leaves all summer/fall last year. They need a little cleaning, but work great for alpha planes. Anyone who wants them, let me know (about 52meg, zipped). They are all PNG format, at 24 bit.
