Rodinal trix agitation

avandesande · Nov 25, 2005

I would like to hear of what your favorite semi stand techniques for trix in rodinal at 1:100, @400.

That's pretty open ended. What would you like to achieve ...or, what have you done ?

I just want a touch of the 'rodinal look', but not freakish. It is some portraits in relatively flat light. I am not going to be upset if it is not exactly what I want, I am just looking for a starting point.

in 4x5? rated 200ASA (not 320)
I mix 1:150 and soup for 50 minutes.
Slight agitation at start, 15 and 30 minutes. Leave it for the rest of the time.

Don't shoot if it doesn't work for you.

Here is my basic portrait solution, for Incident reading, and TX @ EI 400.

I use a diffusion enlarger, #2 paper, and a normal, or soft paper developer,
on fiber paper. It also is a good starting point for enlarged internegatives for platinum printing.

Rodinal 1+85. The attachment shows this ( red curve ) compared to 1+50 with normal agitation.

For a starting point, try 25 to 30 minutes, with 5 seconds agitation every fifth minute.

The look is fine grain, distinct but not oppressive. There is higher acutance than normal agitation, but no significant 'edge effects'. Not, to me, freakish.

The reduced agitation adds a little shadow and midtone density while reducing highlight density.

The second attachment is an example, although it is a little frightening. The light was hard, and the 'snap' was accentuated in printing.

NOTE for BZTS shooters: your conventional calibration technique will not lead to these results. You must adjust your development time to give ideal V or VI density.

Thanks. That is what I was looking for.

Last night I developed a roll of Tri-X in Rodinal according to this "recipe". The negatives look good, will let you know once I find the time to print them

I forgot to ask you how much initial agitation you do: I just did 20 seconds slow agitation.

That's fine. Experts disagree, but I don't think it matters: Rodinal is so soapy there isn't much concern for bubbles and bells. I always give it 15 seconds, and a couple shakes, and a rap on the table.

But I think that is more superstition than anything else.

I have scanned the negatives. It looks like that the shots in the sun have a good separation of values, whilst the ones in the open shade or indoor look a bit muddy. Not sure whether it's a problem with the exposure or simply that you cannot have everything right (both in the high contrast and low contrast scenes). Or maybe I am just not good at scanning?

I have attached a couple of scans of both sun and shade shots where you can see the difference.

Hopefully I will have a chance to make some test prints during the weekend.

Look fine to me: one looks like it was in the sun, the other in the shade . You can simply add contrast to taste !
