 ■ Shutters ^^^ 



THE GREAT THING ABOUT THESE SHUTTERS IS THAT THEY ADMIT 

 MORE LIGHT, EXPOSE THE EDGES OF THE PLATE AS EVENLY AS 

 THE CENTER, AND DO THE LENS NO INJURY BY JARRING. THEY 

 ARE ROLLER CURTAIN SHUTTERS, SIMPLE IN CONSTRUCTION, 

 RELIABLE IN ACTION, AND NOT LIKELY TO GET OUT OF REPAIR. 



For general purposes, the Time and Instantaneous, either before the lens 

 or behind the lens, is the best shutter made. 



For very rapid work, The Thornton-Pickard Focal Plane Shutter 



is unapproached ; works directly in front of the plate, passes an enormous quantity 

 of light, and is the only shutter to do justice to the full powers of the fastest lenses. 

 Very simple, reliable, and not easily put out of order.
