Note: There is a video version of Using the Zone System with Polaroid SX-70 Film, Part 1 at the bottom of this post.
SX-70 film is a remarkable feat of engineering. To think that the entire photographic process—taking a photo, developing the negative, printing the negative, developing the print, framing the print—is all done in one step: take the photo and a finished, framed print is ejected!
That magic comes with a few downsides, the most concerning being the limited latitude or dynamic range of the film. While most camera films might be expected to have a dynamic range of 8-9 f-stops between black and white with an extensive range of grey values in-between, SX-70 film has a much smaller dynamic range. Simply put, SX-70 film is extremely contrasty. The film loves low contrast scenes shot in overcast conditions but good luck capturing a bright sunny scene with deep shadows.
In an effort to gain some level of creative control over the SX-70 film’s limited latitude, it occurred to me that the Zone System might be worth exploring.Continue reading
