Are these photos of photos of have you put some frame before shooting? Kinda confused, but it’s definitely interesting ^^
These are polaroids taken using a polaroid back for a 6×6 camera hence the ugly black frame, if you run this through a mamiya rb67, (or even a 7ii) you get a 6×7 photo and then a nasty black border again. If you run these things through a dedicated polaroid camera though, you get a beautiful full frame. 🙂 I have yet to get myself a full frame peel apart polaroid camera body.
