Tips & instructions for converting a 1960s Polaroid camera into a functional and compact large format 4x5” rangefinder. After the conversion taking pictures in large format will become easy as handling a 35mm Leica camera! Compose and focus your pictures handheld, looking into a large, bright viewfinder instead of a ground glass! Leave the dark cloth at home and forget the tripod! This small guide will show you everything I did to convert my own Polaroid 110B: manufacturing of a custom 4x5" hinged back, attaching a Graflok back, adjusting the rangefinder, using alternative lenses... All with tons of pictures and text. You'll be able to load large format sheet holders, grafmatic backs, polaroid 545 backs, 120/220 slip-in rollbacks in your 110B after the conversion.
