Using the Zone System with Polaroid SX-70 Film, Part 2

Note: There is a video version of Using the Zone System with Polaroid SX-70 Film, Part 1 at the bottom of this post.

In Part 1, I explained the theory behind the Zone System, how I thought it might benefit today’s serious SX-70 photographer and I painstakingly outlined my process for taking the photos required to make a Zone Ruler. If you haven’t, I recommend you take a look at Part 1 before continuing with Part 2.

In Part 2, I analyze my set of “towel photos” taken with Polaroid Color 600 film, build a Zone Ruler, provide some practical tips for using the Zone Ruler in your own SX-70 photography and show a number of photos I’ve taken over the last six-plus months using my Zone Ruler.

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.
