There's a dude on instagram whose pictures are all scanned polaroids. I don't know why he doesn't just take digital photos like everyone else and make them look like polaroids, but he doesn't..It reminded me of an exhibition I saw where across a whole wall was a clustered mess of polaroids that were assembled into a 360 degree panorama from the top of Ayers Rock (a mountain sized rock in the middle of nowhere), giving a strange crystal facet effect where the pictures overlapped. It was also the only 'art' that didn't have a sold sticker on it, I'm guessing because up close it actually looked like a mess, A certain amount of work and expense for something so ephemeral, and then you move on to the next thing...
