There is something completely unique about a polaroid print. Part of that is about the physical presence of the print itself, which is hard to capture in a scan, but including the print border in the scan helps. Of course Polaroid stopped making film a long time ago, which means most of these photograph are made using out-dated film, but this makes the colours even more beautiful in my opinion.
I now have quite a few Polaroid cameras; a 1970s 195 (which uses Type 100 'peel apart' film), a 1990s 1200si (which uses Image film), and (my favourites!) several SX-70 models, also from the 1970s (which use... err... SX-70 film...). May latest acquisition is an SLR680 specifically for the lastest PX680 and PX600 UV+ films from Impossible.
I also have a Vivitar Instant Slide Printer and a Daylab Jr, both of which are used to transer 35mm slides to Type 100 film, mainly for the purpose of making transfer prints.
Which brings me to the thing I love most about Polaroid films; the wide array of different processes you can apply to Polaroid photographs of all different types to creat all kinds of different images.
