i should have added to my original post that i did google but didnt find much. i ve found the wifes old canon power shot 2 and like the idea of using chdk and some home made electronics to rig it to fire remotely. about ten minutes ago i was drinking a brew watching about 6 gold finches squabbling over the niger seeds, the idea is to have a camera semi permanently setup with a remote on the window sill so i can take close up snaps of the carrying s on .
