I bought a Polaroid 'The Button' camera at a charity shop. It's a fairly elderly model, but it works and it didn't cost very much. It takes SX-70 film, which costs about £1 a photo. A cassette of the film costs more than the camera did. I still like the camera, not only because I'm impatient, but also because there's something about a Polaroid photo which is just really, stupidly, cool.

It's not all that nice to use: three, rather arbitrary, light settings, an iffy viewfinder, it's chunky, really quite noisy and when a picture doesn't work out (and this is distressingly frequent) you really feel you've wasted money. But, hell, it's Polaroid! The colours can be really beautiful, the iffy viewfinder just means you get more... novel compositions and you don't have to think (much) about what you're doing, you can just think about images.

Some of these are self-explanatory. Some aren't. Make up the explanation, if you feel the need.
