In the “olden days”, there used to be this thing called “film”. It came in light proof canisters, because once you exposed it to light, you either had a film negative or a useless piece of plastic, depending on how deliberate you were about that exposure. Whether you were taking stills or shooting movies, you essentially used the same stuff. When you were done shooting, you put it back into the canister and sent it off to the lab to process. That process is roughly the genesis of the expression, “It’s in the can”, used to indicate that the shooting is done, and the film is ready to be sent off.
Nowadays, most of us are using digital capture to make images. We have become our own photo labs, spending as much (or more) time sitting at our computers processing images as we do making them. It’s not all bad news – the flexibility and creative range of digital imaging has given us a wider and deeper pallet than ever before. And it means that we’ve been given the opportunity to think of a whole new photographic context for “It’s in the can”.
