Using the Zone System with Polaroid SX-70 Film, Part 1

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!

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.
