It's not, but in the case of stand development I didn't do something wrong. At least nothing that according to common knowledge was wrong. If anything, it was the very long agitation interval that was the culprit.
No it's not "wrong", it's "incomplete" and thus not a real basis for drawing a general conclusion. It's analogous to declaring a developer doesn't work as claimed when you've never bothered to check your light meter or thermometer.
I in no way think you are "wrong" about not pursuing this, since you clearly don't think it's worth the effort. Cool. I just think that making sweeping judgments that are an extrapolation of single data point isn't legit.
(I see this a lot in the wider culture. Everyone wants instant results and jumps to conclusions based on really small data sets or analysis. Clearly, the sun sets because the street lights turn on.)
You certainly are more patient than I am when it comes to trying different variables that may make it work.
Because that's the only way I know to learn new, complex things: Lot's of patience and experimentation.
And far more willing to sacrifice films and perhaps valuable shots to make it work. But I have also burned film and paper for other causes, I'm just not keen on this. I don't see it as a solution to something.
It absolutely solves a problem for which I have never found a better solution. In fact, this exact scenario is what got me down the rabbit hole:
You are shooting a scene with an overall long SBR. However, the principal subject of the scene (the dominant geometry) is, say, in a flat lit shade - the mid-tones are all muddy. Mid-tone contrast is essential to make a print "sing" in a great many, dare I say most, situations.
If you use contracted development to hold both the highlights and shadows, you clobber mid-tone local contrast. (This is the #1 sin committed by strict Zone System use.)
If you use expanded development to build mid-tone local contrast, you blow out the highlights.
If you use a strict compensating development scheme, you'll hold the highlights but you won't expand the mid-tones (see the first case above - exact same problem.)
There are only two ways I know to attack this problem:
1. Use SLIMT to calm the highlights down and then do expanded development.
2. Use semistand/EMA to hold down the highlights and simultaneous expand the mid-tones
So much of a print's vibrancy depends on those middle-tones, I find myself using this more and more and my prints are the better for it.
Here's a scan of a print by way of example . Huge SBR but the interesting stuff was in the mid tones:
As for cautioning newbies that stand development can result in bromide drag, I think it's fair to point out that there's a non trivial chance that things can go wrong, but others have been lucky. In the end it's their film and their time and effort.
It's only "luck" if you are not systematic about it. I saw early results that were really encouraging even though they had development artefacts, so I set about the remove and vary variables until I had it more-or-less dialed in. At this point, I know exactly how to process the film to make it work, and the (few) films for which this does not work reliably. For scenes that benefit from this style of development, I just avoid those films.
P.S. I 100% agree this is not for beginners. I've said so repeatedly and also in my written notes. Someone has to have conventional development under control before they go down this road, and then only if their subjects merit and they are able to see and meter appropriately. Personally, I waited over 45 years to get started on this
