TMY pushed in Rodinal 1:100

[Stephanie Brim]

Before I give this a go by just guessing, does anyone have a good starting point as to what time I should use for a two stop push of TMY in Rodinal 1:100? The Massive Dev Chart doesn't even give push times in Rodinal for 1:50...I'm guessing that no one does this. I did it once in D76...I'd kind of like to see what it comes out like with Rodinal.

Okay, decided to wing it...with good results. The film was exposed at f/2, 1/15th of a second. Developed in Rodinal 1:100 for 50 minutes with five inversions every five minutes. I'll post the images when I get the film dry.

Hi Stephanie,

I'm very curious to see the results as a lot of people claim that Rodinal does not have very good pushing capability.
I am glad you tried it. Please post your images to show us your expierence. Could you add some straight negative scans too?

Greetings,
G

It's going to be grainy...i'm just hoping for pleasant grain. If it's golfball-sized, I hope that it's PLEASANT golfballs.

Also note that I did this with 35mm film. Your milage with other formats may vary.

Okay. The biggest problem I saw was that details in the shadows are nonexistant. I think it would work with some applications and not others.

Pretty typical for underexposure. My favorite push is Tri-X in Diafine. Normal speed is 1600. Gives adequate shadow detail.

Agfa's suggested times for Rodinal and TMY are (1+25) 6', and (1+50) 11'

It's safe to estimate a 1+100 time based on the relationship of the lower dilutions.

11' / 6' = 1.8x So, 11' x 1.8 x ( 20' ) is a good place to begin for 1+100.

When we use reduced agitation ( every 5th minute ) it is a pretty good rule to double the time for normal agitation: 20' x 2 = 40'.

The factor for a two stop push for TMY ( taken from the Kodak technical publication ) is about 1.33 x. A factor of 1.5x isn't a bad idea if you are using to minimal agitation to discourage the highlights from running away.

SO, a good estimate for a two stop push in Rodinal at 1+100, with minimal agitation, is 40 x 1.5, or 60 minutes. The 10 minutes extra beyond the 50' you used will make a big difference.

Rodinal's strength is in the midtones and highlights. Compared to D76 or XTOL, it gives up a bit of shadow detail which can be compensated for at normal speeds; minimal agitation will give a full box speed with great tonality.

But PUSHING ( which with rare exceptions ) will never build density in the shadows: increasing film speed.

You CAN expect TMY at 1600 to 3200 from XTOL. At 1+1 with reduced agitation, it is a handsome look.

Hi Stephanie, I used TMY with Rodinal 1:100 for many years, I've since changed to another film. My time was 17 3/4 minutes at 20 deg C. Of course we all have different times, mine were arrived at originally by using a densitometer and the ASA was 400. Not much more I can say really, they were always excellent negatives.

.....Sorry, I forgot to add the 2 stop push bit... my 'N' was as I said 17 3/4 mins. N +1 was 22 minutes and N +2 was around 27 minutes. That is all from the densitometer mathematics. I never actually pushed with Rodinal, there are other developers better suited to perform this task. Good Luck.

I kind of like the look that I got from the first two. The street was pratically deserted even though that street connects to Old Highway 20. The low shadow detail kind of gets the mood for the night.

Oh, and as per Mr. Cardwell's post, The first thing I thought was 60 minutes. I should have stayed with my gut on this one.

I don't know if it's been said here earlier, but with such a high dilution, it's also important to make sure there's enough developer in the solution to prevent exhaustion. I processed two rolls of 35mm in a 2-roll Paterson tank, with just enough developer to cover the two spools. It turned out to be too little developer, and it wouldn't have mattered if I had developed for twice the time. Probably just more fog.
Then I switched to doing one roll in a 2-roll tank, but fill it with developer solution at 1+100, and I got solid negatives again.

Just a thought...

I used a two roll tank with 500ml of water and 5ml of Rodinal for one roll.
