Process promptly.. But what is promptly?
If like me, you've got more than just a single camera, you may recognise this.
There's film in one camera with a couple of frames exposed, and then for a while there's a need to use other gear. With some cameras it's possible to do a midroll rewind and carry on with the same film in another. But not all cameras can do it, and even if possible, it's not convenient. As a result, with the constant indoctrination of the 'process promptly' message on the film boxes, I'm wary of putting film into a camera that I'm not dead sure of I'll use continuously till the roll is finished. And that's just plain silly.. that's keeping me from using some of the gear I have. Why not put a roll of film in every camera and just pick the one up I'd like that day. But this would mean some may only get used once in a month, and the film would sit in there for maybe a year, or two.
Now, how bad would that be? Does anyone know how long a taken image can last without processing and still be good? In other words, what is the 'promptly' bit in process promptly?
