    couldn't we just use the miniminal possible amount of rodinal and rely on exhaustion?

    We could, but development would be uneven, a graduation from top to bottom.

    There are two things we might accomplish with minimal agitation, one is to induce actuance effects.

    The other is to raise the shadows relative to the highlights, the curve pivoting at the midtone, as it were, on a fulcrum.

    Essentially we 'push' the shadows while 'pulling the highlights'; the shadows continue to develop while the highlights develop until they stop.

    Depending on the film, you would end up with flat highlights, too flat. So, you balance the agitation (highlight control) with the time (shadow control) and place the midtone by exposure. Well, that's how I use it !

    does accutance effect scale with format?

    Finally, someone realizes the possibilities beyond making sharper appearing prints.

    There's still hope!

    Apparently you've not heard of Meese and James' work of developer actions in the vicinity of muffin mixing.......

    Try sideways

    In some work I was doing on sorta-semi-quasi-stand developing I got erratic results on bromide drag. Sometimes none, sometimes some, I think varied with the film, even. Pretty much the observations here.

    There is no law that a developing tank must be kept upright if it is liquid tight. I found that by laying it sideways and then giving it a partial roll at intervals gave drag free negs.

    The tank should be full, although I can't image film in any air bubble drying out while up.......

    Works for me too... (Thanks to Don), I am using minimal agitation with Neopan 400, a film with an ill deserved reputation for being overly contrasty and loving the results with Rodinal. Sharp, even and lovely microcontrast.

    An example of the above combination Neopan 400 in Rodinal 1:50 Minimal Agitation.
