Digital - you loose resolution for the sake of convenience, but it might be worth it at times
Hyperfocal - the most depth of field from a lens that is possible without it being a pinhole camera
Photograms
Silver Gelatin - the classic photogram
Cyanotype - nice in that you really don't need a darkroom
Van Dyke - about the same speed as cyanotype, but silver based hand made emulsion
To be added:
Reversal - using a continious tone lith internegative to end up with a positive photogram
Lumens - uses old photo paper out in the sun and then fixed. strange colors and shades
Anthotypes - plant extracts can be light sensitive too
