Roll film masks / compositional aids intended to be used with Chamonix 45F2 cameras. These may also fit other Chamonix 4x5s but only the 45F2 has been tested. They hang off the circular ground glass tabs which are also used by the Chamonix hood and ground glass protector. These are compositional aides to help with framing when using various roll film backs to mask out the parts of the ground glass which will not be exposed to the roll film back being used. They are available in several sizes (6×4.5 up to 6×12).
These have been tested by myself and a small number of customers but I have not been able to gather information on use with all film backs and sizes and so are currently a beta product.
These were designed by me and printed using Atomic Filament Carbon Fiber infused PETG on my modified Prusa MK3 printers.
