When you see a photo with multiple copies of the same person in it, you might think it was done in Photoshop. And it usually is. There’s another method that requires four things:
– A tripod
– A slow shutter speed
– A handheld flash (not attached to camera)
– A very patient friend
For this one I used a 20 second shutter, which is just about long enough to get four exposures of someone, after a few hotdogs and drinks by the fire. Get your subject ready for the first position, open the shutter, and use the test button to flash the hell out of them. Have them move, and flash them again. When they’re not lit up the sensor won’t record much of anything, so you won’t see them moving.
Two key things to remember are to avoid overlap in the positions, and to remember your inverse square law. Changing the flash-to-subject distance too much between positions will make some instances dimmer, like the one to the far left here. Also, darker backgrounds are preferable — you can see where the dark background makes a more solid subject, but putting them in front of something bright (like a fire) turns them transparent.
If you’re really strapped, you can use a point & shoot camera with a flash to light them up, and get some bonus “making-of” photos. Not recommended.
This is really a form of light painting, just using a brief, strong source of light instead of something constant and less powerful. You can do self-portraits this way too, but it’s a little more complicated. More fun with flash at night coming up.
