Its a luxury to have enough cameras that a roll of film can languish for a year and a half without being finished. I'd wanted to try out some Cinestill 800T and had grand ideas of low light shots in and around London so I promptly loaded it in my relatively new (to me) Nikon F4 and went out and got a few shots one evening after work. However the longer nights soon came and I never prioritised getting out to really try out some shots with this film. So it sat there for a year and a half before I picked up a Hoya 81B filter so that I could use in natural light, get the roll finished and enable me to use the F4 once again with some Portra or Ektar. The manufacturers website for the film couldn't be clearer: "The new boxed CineStill film has a 2 year shelf life, and should be stored in the fridge and shot within 6 months of purchase to achieve optimal results"
But instead of wasting the roll I figured I'd get it processed anyway and see what came back. As you can see, weird stuff happens. I'm not sure what that red line is as I'm pretty sure my F4 doesn't have a light leak. The roll was professionally processed by my normal lab and the weird bubbling in the emulsion is only present on the first section of the film which was mostly, although not exclusively, exposed around 1.5 years before it was developed. To my surprise though the latter section of the film actually came out ok and with some pretty decent colours (using Negative Lab Pro to convert a positive scan with a Nikon LS-4000).
