What is the grainiest bw film and developer?

[TheGreatGasMaskMan]

PT. 1:
HP5, Rodinal 1:6, 1 min, 45 s. 68ºF, Petri 7s

Pt. 2:
there were two 1:6 frames with some sort of weirdness:

 

[TheGreatGasMaskMan]

Hp5, Rodinal 1:3, 1 min, 68º F, Petri 7s.

Rodinal 1:3! That's nuts. Great pictures.

Hp5, Rodinal 1:3, 1 min, 68º F, Petri 7s.

I got the notification for this, misread it, and thought you developed for 7 seconds

Strange that no one has mentioned caffenol as a developer. Use the formula for slow films on a high speed film e.g. 400 or greater. The Arista/Fomapan films work for this.



Edit note: Curse you autocorrect!

 

[TheGreatGasMaskMan]

Hp5, Rodinal 1:1, 36s, 68ºf. Petri 7s

Next low dilution cycle- Ultrafine Finesse 400/ ORWO N74

I've used caffenol for developing expired Kodachrome, but not much else. might be worth trying down the line

assumed 20(ish) years expired Tri-X in Rodinal 1:25. this convinced me I should be considering this film for high grain.

A good deal of fog helps; you end up with a muted negative that needs a lot of contrast boosting to normalize contrast, and that will boost the grain along with it.

Another thing that you could try is to use a red filter; not orange, yellow etc, but red. The red-sensitive part of a panchromatic emulsion tends to be on the grainy side. Of course, you get the particular color response for free to go with it...

 

[TheGreatGasMaskMan]

I know I've got some red filters somewhere- but all these were shot unfiltered

Rodinal 1:3! That's nuts. Great pictures.

Well it certainly is to a Scotsman like me Actually if the same size prints looked similar on a darkroom print I'd say that Rodinal 1+3 looks OK but I do wonder what, if any, improvement there is on 1+25/50
