This is fun. Just hit "D'' to remove the heads-up display, then hit ''F10'' to remove the tactical read-outs, then hit "F12" to actually take the picture. Monkey around with ''F2'', ''F5'', "Home","End","PageUp", and "Page Down" to manipulate the camera....hitting "F12" to again take the picture. Then push "F9" to put the tactical readout back up, after you're don with the picture.
While setting up a picture, try hitting the [ ] keys to slow the game down, so you have time to line up the camera.
The pictures will show up under c:/program files/activision/SFC3/screenshots........
Sincerely-
