Great to see these again, Rob and you most certainly should get another Instax camera.
I'm quite a fan of instant film although I only appreciated it as an 'artistic' medium after stopping using it for work (and after seeing the marvellous manipulations that Ralph Steadman did with the Polaroid SX capsule films: you can move the dyes around with a stylus before they stabilise - he created a wonderfully cruel 'caricature' of Maggie Thatcher). We used polaroid peel-apart film to test exposures on some technical shots way back, but the main use was on microscopes, mainly onto 5x4 and often in mono, which gave both a usable positive and negative to use later. Polaroid also made a microscope adapter for the SX70 (and I still have one) that was useful for a quick record.
After Polaroid ceased to be I found a few boxes of SX70 in the fridge and used it for general use and liked the results a lot. In fact I still have some 5x4 material in the fridge that isn't getting any better. Anyway, then came New54 and the Impossible Project (now called Polaroid again) and although pretty 'interesting' in the early days (New54 had to give up due tp supply chain problems) it is now back close it its old self.
I hadn't tried Insta until fairly recently though, but was tempted by a 5x4 back that Lomography produced. I must dig out the shots, and do some more. A company in Hong Kong also produced a back for Hasselbad V-mount and I bought one, but have yet to try it, but I will, spurred on by these images. Thanks, Rob.
