I have some Polaroid shots from the 1980’s, taken with a Polaroid SX-70 instant camera. Since I’m working on my pets mini album, I don’t have enough room to fit all of them with their white borders intact.
Unsure of whether or not it is safe to cut these photos, I Googled “is it safe to cut Polaroid photos” (minus the quotes). According to a forum post quoting Polaroid’s FAQ, it is safe! They say as long as the photos are at least 24 hours old, the picture is finished developing and the chemicals have neutralized; so, it’s safe to say my pictures are safe.
I used my Fiskars rotary cutter and cut them down so all that remains is a thin white border around each square picture.
What the backing displays is really interesting: a ghostly, whitewashed image. Because the backings are powdery with dried chemicals, I doubt they’d last in an album. So, I took photos of them to illustrate what Polaroids look between the layers.
