Are there any labs out there that give each film the correct development, or is this another case of "if you want something done right you have to do it yourself."?
If by correct development you mean »use a suitable dev time for a specific film« -- then, yes, most labs will do that. But as most labs will be processing your film in a big tank together with other films of all kinds, they will use one and the same
developer for all of them. And as these films will come from all kinds of people doing very different things to their films, that developer will have to be to be some sort of ›universal‹ developer that will level these differences, to make sure all of them come out equally okay-ish. If for example I were to have my films developed at the lab that's operated by a renowned local photo retailer and APUG partner, they'd soup them in A49, a developer that (1) seeks to minimize graininess by dissolving the edges of the grain inherent in the film and (2) seeks to ›compensate‹ contrast by flattening the response curve at an ›earlier‹ point than other developers [what would be the North American counterpart of A49/Atomal?]. Both these characteristics are excellent in this particular context: you'll have less customers complain about graininess (they may not notice the compromised acutance because their negs were never too sharp in the first place), and you'll be able to give them more easily printable negatives even if they botched up their exposure. Will it be a »correct development« by the standards of what
you have in mind? You decide...
