COMPOUND SHUTTER
The Compound Shutter is an automatic and setting shutter combined. Automatically, either time or bulb exposures may be made, while it may be set for speeds of from 1 to 1/150, 1/200 and 1/250 second, according to size of shutter. The shutter leaves are formed of segments opening in star shape, giving even illumination over the entire plate the instant the exposure is started, and it has an iris diaphragm. Case is made of aluminum, and accurate adjustments can be made with shutter in any position. It may be operated by either bulb or finger release.
The Compound Shutter is regularly supplied on the Premoette Jr. Specials Nos. 1 and 1A, Filmplate Premo Special and Six-Three Premo Cameras.
