Very strange.My Dad worked for Polaroid for almost 40 years and one of his responsibilities was to test new film and cameras.As a result,we have *thousands* of Polaroid prints (family pictures) from the 50's,60's and 70's and most of them (not all,mind you) still look darn good.
I don’t know what went wrong with ours then. Mom’s are the peel away type, and she keeps them in albums. Our pictures from the late 60’s through the late 70’s look terrible, with little to no color left in them.
My One-Step (SX-70) shots have been kept in a scrapbook and packed away in a box and look nearly as bad. My prints made from my 35mm SLR from the same period of time look great.
Other than light, what else would cause this?
