Why scanned negs just aren't the same (sometimes).
It's perhaps quite a valid point that; 'if APUG can accept a scanned print, then why not a scanned negative that shows what I am going to print later'.
Well I'm going to go out on a limb here a bit. It does in fact require a degree of skill to produce a good print from even a good negative in the darkroom. In fact many would say that the physical actions, knowledge of materials, process control etc are substantial.
In PS there are the same functions available as we have in the darkroom. But they are refined, and able to be implimented incrementally and retrospectively to an extent that is practically impossible in the darkroom. Sharpening techniques that go further than resolving scanning problems, and actually can address negative imperfections as well. Highly intricate dodging and burning with localised contrast adjustment can be implimented relatively easily. Not to mention, the knowledge of techiques such as split-grade printing or flashing, are just not required when producing a print from a scanned neg.
At the level that many are operating at, in APUG, these things make quite a difference. So I think that what bothers Jorge (if I can put words where they weren't asked for), is that the act of posting a neg scan dismisses a whole side of the craft of traditional photography that many value quite highly. Sure one might be genuinely honest with themselves and only make changes to the scanned neg that they will achieve in the darkroom later. However, the normal preference for photographers is to be behind the lens rather than under it, and I suspect that this honesty would be difficult to maintain, if one got in the habit of regularly PS'ing all their negatives.
For this reason, I will always look at a scanned neg, and appreciate it for what it is, but with a niggling (and very slight) reservation. I personally tend to value images that are scanned from prints for what they are, and the extra work involved to get there! (2 cents)
