My two year—and counting—foray into the wild world of Polaroid SX-70 photography has taken me in various directions. Recently, I have been working with Polaroid Black and White 600 film and this has led to my current project at Camp Morton Provincial Park in Manitoba.
Established as a Fresh Air Camp in 1921, the site was once an escape for underprivileged children from nearby Winnipeg. Set on the banks of Lake Winnipeg, the eleventh largest fresh water lake on planet Earth, it would have been a happy place to swim, play, breath in fresh country air. The camp ceased operating in 1971 and has since been transformed into a Provincial Park. While many of the unique camp buildings have been retained, they are all in various stages of decay. In particular, lakefront stairs, retaining walls and other structures have been ravaged by the angry lake, which completely freezes over in winter.
It seemed a perfect subject for a black and white photo project.

It would be nice to adjust exposures in ½ EV increments with my MiNT SLR670-S camera. Unfortunately, the camera can only make full shutter speed adjustments, one EV at a time; there is no ability to select in-between speeds. While most manually-controlled cameras allow f-stops to be set in half or third stop increments, the original SX-70 cameras that MiNT refurbishes have a ‘fixed’ f/8 aperture.
All too often, I will take a meter reading only to find that the best exposure lies between two shutter speeds, for example between 1/125s and 1/250s at f/8. Because I can’t change the aperture, I’m forced to choose the lower shutter speed, which will result in a slight over-exposure, or the higher shutter speed, which might be darker than I wanted.
Because I’m shooting Polaroid SX-70 integral film, which has a very limited latitude, especially in the highlights, these seemingly minor compromises in exposure can have a major impact on the quality of the final photograph.
