Stand Development Too Dense?

[MattKing]

I can only repeat what others have said to me about this, and its possible that its speculative. But what I gather is that during the 30-60 minutes that the tank sits undisturbed, development products (bromide?) drift towards the bottom of the tank and have the effect of increasing developer activity in the zone where they built up. Its got nothing to do with the speed at which the tank gets filled - as you said, a few seconds cannot possibly make any difference.

IIRC, the bromide byproducts would tend to impede development, not increase it.

I never use trays for sheet for semi-stand or stand. I use BTZS tube for sheet film. I feel that it works best when film is verticle/on it's side. Edge effects are not washed away with semi-stand and Pyrocat.

I don't use trays, either. I use tanks/hangers for a minimal agitation technique and homemade development tubes for EMA (extreme minimal agitation.) Both techniques have the film in a vertical orientation and I've never used anything but Pyrocat-HD when employing this type of development.

Just started experimenting with stand development...

What were you hoping to achieve with stand development?

What were you hoping to achieve with stand development?

Better control of the high values out here in the harsh light of the desert southwest.

What Alan said plus enhanced edge effects....
