One of the main reasons film photography gets overshadowed by SD and memory cards (apart from analogue photography being a pricey hobby) is that film stocks have shelf lives. Each emulsion is formulated differently -- and a lot of unpredictable things can happen via daily-basis events such as prolonged exposure to sunlight -- loss of ensitivity, decreased contrast, color shifts, leaks, etc.
However, those have become part of the charm in film photography. Only few manufacturers are left in making emulsions. Photographer and blogger This Does Not Compute tested a 35-year-old B&W film, the Kodak Plus-X. He shares his review of shooting an expired film, and while there are drawbacks, there is enjoyment in the process.
