The Polaroid SX-70 is a beautiful example of mid-century industrial design, and it had a promotional device of great artistry to match. I adore this film so much. It presents the simple joy of photography and, without hyperbolizing or talking down to its audience, gives a comprehensive explanation of how the camera works. It wasn’t until the end that I learned that it was made by Charles and Ray Eames, but I probably should have known within the first few seconds. Their style and skill is obvious.
