When I was a food and product photographer, I could visit the cooking lab to collect the items for the shoot, get to my studio, do the shoot, then pop to the lab and have finished negatives and prints back all within a day. That was a very fast turnaround but still had drawbacks. For one, there was no way to experiment with pushing and pulling, or using different chemicals. It was also rather expensive.
That kind of turnaround is almost unheard of now, for everything from professional work to high street ‘photos in an hour’ services and I think that might be a good thing.
