1: dSLR on manual settings (set from2-10″ or bulb exposure) to be able to take the pictures
2: very dark room or nighttime outdoors so light doesn’t corrupt the final image
3: tripod to hold the camera still
4: human subject so there is movement in the picture (the multiple exposure)
5: strobe or flashgun to cause the multiple exposure
6: someone to serve as an extra pair hands to hold the light or to take the picture
7: aperture between f/8 and f/16 to be able to capture the flash exposure
8: camera on manual mode as ISO 100 to see if the room is dark enough to be able to shoot for this technique
9: pose wait for flash, then pose again so the multiple exposures actually happen
10: a single light source so the subject actually shows up in the picture instead of a blank, black screen
