An old Polaroid 110A foiding camera, for which the film is no longer available: we inherited it from Sam's father, who we think inherited it from the guy who had the job before him. It's rangefinder, which means you focus using a little focusing window at the top.
It folds up pretty small for a 4x5 camera:
Cut the back into bits, do some horrible things with duct tape, and you can fit a 4x5 film holder onto it.
This is my prototype conversion: I'll do something a bit neater when I confirm that the focus is ok and so on.
This isn't an original idea - I was looking through one of the photography forums when I saw someone talking about doing it, though a much more elaborate one that isn't appropriate for this model of camera. Having build a view camera before, this wasn't a hard project ...
I did two test shots earlier today, but I haven't had a chance to develop them yet.
I have to work out if, and for how much, I can get 4x5 slide developed and scanned. Though mostly I just want to make some 4x5 slides. Slides are pretty.
I've seen polaroid backs for Holgas which is what I got confused over when you mentioned polaroid there. With the Holgaroid you can repace the back so that you can take polaroid photos using the holga. How neat would that be?
And looking more on the Holga website they suggest cross processing slide film as negative to get colour shifts. So that lies a little further down the line for me. Ad astra per aspera
Shall have to try again.
