The Whittaker Micro 16 is a subminiature camera for 16mm film cartridges. It was sized like a smaller deck of cards and could be fit in an empty pack of cigarettes. It was made by Wm. R. Whittaker, Ltd. in Hollywood, Los Angeles, California since 1946. It had a built-in waist level reflecting type viewfinder. An optional sports finder was available. Detectives liked that camera since it could be hidden in a pocket or just your hand. The camera was produced from 1946 until 1950. The 16mm film cartridges were double perforated and had 24 exposures. The lens is an achromatic doublet f6.3 fixed focus and the camera has a single speed shutter. The Micro 16 was available in chrome (polished aluminum), black, blue, green, and grey. The green is seen in an anodized matte finish, a rough look enamel, and a lacquer finish. There are also variations in having the pebble dash top and bottom being in black, green or grey with the rest of the camera as polished aluminum. The camera has a plunger film advance that when pressed all the way in, will lock in for storage and you press it in again to release it for your next session. The film cartridges are made of tin and the feed and take-up cartridge are identical. The camera has three aperture settings of "BRIGHT" f11, "DULL" f8, and "COLOR" 6.3 and can be set using the switch beside the lens.
