Pinhole Mamiya RZ67 & Polaroid? Basic Questions!
In a weak moment I purchased a Mamiya Body Cap Pinhole and a 'Pinhole Factory Exposure Calculator' on ebay.
After reading the various threads here I have rough idea how to take some pinhole photos with my Mamiya, and given that I have a few packs of soon to be expired Polaroid colour & B&W film I was considering experimenting.
With the colour polaroid is there a reciprosity factor I need to add to my exposures?
Also can anyone explain how the #$^&*( the Exposure calculator works? It has time on the outer ring and f numbers on the inner ring. Is there something missing - the pinhole size? or am I missing the point entirely?
I will be getting a book from the Pinhole Resouce centre but wanted to try some first experimants this coming holiday weekend - 4 days off work!
