1. Blow out the background. You need a white backdrop and at least two lights -- one each for subject and background. First, set your main light and exposure, using a wide aperture to give you just enough depth of field for your subject, but not the background, to be sharp. Then set the background light's power at least 1.3 EV greater than the subject exposure. Eliminate shadows by keeping your subject far from the background. Rosenberg put Mooka on seamless white paper on a hard floor, so the paper wouldn't dent, and used Chimera white umbrellas with his Speedotron Black Line 2400 light heads and power pack. He shot Kodak T-Max 100 using a Hasselblad 500C/M and 80mm lens.
