Even in this age of digital cameras, there is still something truly amazing about Polaroid Type 55 positive/negative film. Rated at about 32ISO (rather than the recommended 50ISO), this film is capable of recording superb detail and tonalities. With Polaroid Type 55 4×5 film, each exposure yielded a positive 4×5 polaroid print and a 4×5 negative that could be used in an enlarger for printing. My approach to using this film has always been to treat it like regular film, compose the image and expose carefully, then process the film when I get home. Using the Polaroid back I would do this processing in my darkroom, keeping any light exposure of the negative to a minimum until the negative had safely cleared in a sulphite solution. Then I would complete the processing with a wash period, photoflo immersion then dry just like a regular film. You now have a 4×5 contact print in one hand and a perfectly usable 4×5 negative in the other, what a bargain! This image of the Dune Cabbage is an enlargement from Polaroid PN 55 made on Forte graded paper. This Dune Cabbage (Arctotheca populifolia) was photographed near Cape Leeuwin, Augusta in Australia’s south west, although this successful dune coloniser is widespread around coastal regions, it originated from South Africa. Apparently the leaves can be peeled and eaten as salad or lightly steamed. Here’s one I prepared earlier.
