Hey there, fellow film enthusiasts! You know, just like that leftover pizza in the fridge, used film also has a shelf life (although I wouldn't recommend eating it). If stored properly, you can usually keep it for about a year before developing. But, just like my grandma's fruitcake, the longer you wait, the more likely the quality will degrade. So, my advice? Develop your film as soon as possible to get those stunning, crisp images. The film's not getting any younger, much like ourselves, eh?
