KODAK BALL BEARING SHUTTERS
This shutter works automatically and operates with remarkable smoothness and precision. The leaves are made in five segments, mounted entirely on ball bearings, and open and close in the form of a star, admitting a much greater amount of light in the same space of time than any other type of shutter. All except the No. 0 have variable indicated speeds of 1/25, 1/50 and 1/100 second, operate for bulb or time exposures, and are fitted with indicator for registering each exposure as made. The No. 0 is graduated for speeds of 1/25 and 1/50, has no registering device and operates with finger release only.
The Kodak Ball Bearing Shutter is supplied with the Premoette Jr. No. 1A, Film Premo No. 1, Pocket Premo C and Premo No. 8; the No. 0 size with Premoette Jr. No. 1.
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.
