Always was curious: Was the Bimat system ever used on anything else than autonomous spacecraft?So called stand development seems to be the refuge for those who shy away from giving film conventional development because they can't, won't, or don't want to learn how to burn in highlights while enjoying a full spread of shadow tones and mid tones.
And why is it called stand development when only half the system, the film, is standing while the developer molecules are free to flow and diffuse at will? Maybe real stand development should be like the old Bimat process where the developer is a gel and no liquid phase is present.
Why do I have to waste time during printing, waste expensive paper “to burn” in highlights, when I can simply modify aggetation method, so my highlights don’t build up too quickly ? That’s what stand development does; it allows the silver grain to reduce slowly, which makes it small. And compare film under enlargement. And tell me what you see compared against film developed as “stand”. ??? Optimizing masking, of highlight grain in pyro developer, semi stand development for control density of highlights, optimizing mid tone expansion, is for some a sound strategy, and is easy printing! I don’t get the fuss with “the haters” out there

Try continually shaking your film developing tank constantly for your slotted time like a mixing a martini; shaken/ not stirred. And compare film under enlargement.

One of the ways to increase the 'edge effect' is with the carbon printing process itself. Carbon prints can have significant raised relief, with the blacks being thicker than the whites. Imagine the diagram in post #15 was mapping the height difference of the emulsion between two tonalities as an interesting edge effect, and how the affects how we see the image.Andrew O'Neill makes excellent use of enhanced edge effects. When those are combined with his Carbon Transfer work, it is impressive.
Wow a balanced comment on this super controversial subject, Matt, as tends to be your modus operandi. A rare gem indeed in this B&W worldI don't like what stand does to mid-tones, and I'm happy burning highlights.
And I care the most (usually) about the mid-tones.
As the saying goes, YMMV.
The problem is that good information can be that which the respondent imparts and in many case a lot of what the respondent imparts is different from that which another respondent imparts. At times this leaves the questioner with no answer at all, especially when different respondents do not in fact "talk to one another" for the benefit of the questionerSorry, pentaxuser, but especially in the case of a beginner, good information is a lot more useful than “balanced” information..
But I do not want my highlights held back at all.Well, not that I’m recommending it (I wouldn’t), but there isn’t much about stand development that inherently compresses contrast. It expands contrast just fine.
I'd be curious to shoot two rolls side by side, exactly the same, one with stand development, one without, and seeing the extent to which a difference could be distinguished. .
That takes real talent.

My guess is the difference isn't as significant as discussed. I usually stick to agitating normally, although I'm lazy by nature and do like the idea of just dumping in my developer and leaving my film to sit for an hour until its ready for me.
Either that or its thread standing where you let threads develop to completion before indulging in some needless agitation to see if you can create any more edge effects. More likely it will just create more drag tho.
So I will get the same highlights I do with an active developer with constant agitation for about twice the 'normal' amount of development for scenes of a SBR of about 5 or 6 stop range to get a DR of about 2.8?Don’t worry. It doesn’t do that. Still not suggesting it though.
You're in luck! I have done this, with HP5+. I don't have the prints any more, so you'll have to be satisfied with my half-baked recollections.
The shot had some deep shadow, some open shade, and some full sun. The stand developed film (Rodinal 1+150, which I found produced contrast very close to normal development) had noticeably denser shadows, and slightly flatter highlights. The change in highlights was not what I wanted; I like bright highlights, and I will increase agitation if a given film isn't delivering on that front. However, the boost in shadow detail was potentially very useful. The grain was no different, and neither was the sharpness.
I don't recall seeing bromide drag in that test, but I've seen it on other films where I used stand development. That's the main reason I don't use it any more. I'd probably only consider it if I had a subject with a huge SBR.
