I bought my first Polaroid-camera in 2006. It was a 635, one of the classic fixed-focus "get our camera cheap - buy lots of our expensive film".
Film was expensive, but back then Unsaleable3 sold cheap expired film. And then just three years later, Polaroid stopped their film-production. I already had a pretty good stock of film, and when I heard the news I bought even more. Fortunately The Impossible Project has now started film-production again, although the new film is not quite there yet.
Most, if not all, of the polaroids on this page were captured with either the SX70 or the SLR680. The film used is mostly 600 and 779 - some of it expired. In recent times I have begun using the film from The Impossible Project, where my favorite choice is their Silver Shade film.
