More grain negatives

[nikarlo]

For pictorial experiment I wish have some negatives with much grain.
Now I'm trying with delta 3200 rated at iso 12000-25000 developed in rodinal, but I wish find another film to do this.
Any suggestion?
Regards, and sorry for my English.... :angel:

well, you have a number of ways you can approach this.

1 - shoot wider, and crop more.

2 - develop in dektol. that's some grainy stuff

3 - the delta 3200 idea isn't so bad. are you not liking the results? you could also try pushing something slower.

4 - try a higher temperature in development.

I never tried developing film in Dektol. Interesting concept!

Won't higher temps lead to emulsion reticulation, rather than grain?

I used to push Tri-X to 1600 and dev in straight D-76, which got me pretty grainy negs. This was back in '79, and I know the emulsion has changed since then. Any recent experience there?

with most emulsions, you'd have to use boiling water to reticulate. I meant somethingl ike 75 degrees instead of 68. maybe 80. That should be fine, still.

Definitely avoid any kind of solvent developer. So D76 at least at 1+1 if not 1+3. I think that might be a good start - push a film, dev in diluted D76.

And with plus-x?

Dektol was once sold in in a single use kit called a Tri-Chem Pack. One of the uses in the instructions was to develop Verichrome-Pan.

I have reticulated B&W negatives (inadvertently) using temps above 80 degrees F. I think it is the temperature difference between consecutive solutions that causes the reticulation. I learned not to do that again

You can also use a grain filter in your enlarger. If you are scanning, I read somewhere of a digital filter which can also increase grain effects. As for me, I don't want anymore grain than you get with Forte Pan 400 in D-76.

If you want big grain, you could try shooting Kodak High-Speed Infrared (without a filter for a close to normal tonal response), and developing in Rodinal. This film has no anti-halation backing, so highlights tend to bloom a lot.

 

[pshinkaw]

I forgot to mention, you can also shoot 16mm (Instamatic 110 cartridges)

Terrific depth of field, BIG grain.

A fine rangefinder camera that uses 110 can be purchased for only about $10 (US).

Delta 3200 + Rodinal 1:50 should put you in the ballpark

Reticulation is hard to do with modern emulsions. There used to be a chemical that could cause it though.

Grain is caused by many factors. Density is one of them. You may find normal exposure with over development may help. But you are fighting the chaps at Kodak and Ilford who have been working very hard to reduce grain. What you need is some old emulsions. Unfortunately, Lucky is now working with Kodak and they are using the same technology.

Have you tried under developing lith film in a weak developer? That may give very rough results.

I am also interested in enhancing grain. What lengths of times would you all (Paul, Allan, Gene) recommend for your respective methods?
If I am understanding correctly, I need to use diluted developer, maybe warmer, probably longer than straight development times.
Do you think it would work to recycle developer I have already used previously?

Rodinal has a reputation for acutance at the expense of grain... and its grain is even sharp! So if you'd like fairly prominent and crisp grain, might give Rodinal a try with, say, Tri-X.

 

[GeneW]

Doug, Tri-X (the new stuff) is a little finer grained and it actually looks great souped in Rodinal. Not at all as grainy as it used to look. HP5 in Rodinal, though, is still very, very grainy.
