I also bought an Instant Back for my Belair X 6-12 Jetsetter. It’s a lot of fun (my niece and nephew love it!) even though it’s not the easiest thing to use. Fuji Instax film is notoriously sensitive to light and even though it’s rated at ISO 800, I think it behaves more like ISO 3200. The Instant Back comes with two ND filters to use with the Belair X 6-12 in order to reduce the amount of light reaching the film and instructions on how to control exposure by playing with the Belair X 6-12’s ISO dial. Even when you follow the instructions, your photos almost always turn out under or overexposed.
These were taken in July 2014. The first is of the new South Health Campus in Calgary, while the rest are from Il Giardino Italiano (Italian Garden) at Hastings Park in Vancouver.
