Chapito.

L'ouvre bite non plus n'est pas nouveau et certain ne savent pas s'en servir à 20 ans.

Du Français, de l'Anglais, du labo couleur (15,5/20 ) et de la techno

"Hello, here is the chart of old times for TRI-X (I know we are talking about HP5 but the times are from an old magazine from the eighties, both films have changed a lot, well... HP5 did not exist only HP4, I only put this chart to serve as inspiration for testing).
 
400 ASA 20 c.c. per liter 12 min.
400 ASA 10 c.c. per liter 25 min.
800 ASA 10 c.c. per liter 35 min.
1600 ASA 15 c.c. per liter 40 min.
3200 ASA 12 c.c. per liter 60 min.*
6400 ASA 12 c.c. per liter 90 min.**
 
times are for 20 Cº.
at 18º increase times in 1/3
at 20º decrease times in 1/5
 
* two baths of 30min. each with new developer each time.
** three baths of 30min. with fresh developer each.
-----------------------------------------------------------------------------------
Think about newer films do not offer this big pushing oportunities,
and also that if exposed in sunlight it allways pushes more than in artificial light.
----------------------------------------------------------------------------------------
FRIDGE DEVELOPING
----------------------------------------------------------------------------------------
This can be done in a frezzer with a steel tank, temperature should start at 38º C. and at the end of the development 30 minutes later it shoud be at 5ºC. It should give 1600 ASA on TRI-X.
 
Now for people without a steel tank or a fridge.
 
800 ASA
fist bath
rodinal 5 c.c. per liter (1:200) 5min. at 35ºC
second bath
rodinal 10 c.c. liter (1:100) 25 m. at 15ºC
 
1600 ASA
first bath
rodinal 10 c.c. per liter 8min. 35ºC
second bath
rodinal 10 c.c. per liter 42min. 15ºC
 
if reticulation (very grainy or snow flakes) problems happen, use a intermediate bath of rodinal at 25º.
------------------------------------------------------------------------------------
Then the last thing about this article, Rodinal with sodium sulphide, it softens grain, too do this effect mix sodium sulphide with the developer, as many grams of sulfide as the c.c. of rodinal and up to double this quantity with a maximum of 75 gr. liter.
for example rodinal 1:100 is 10 c.c. per liter. so add from 10 to 20 gr. of sodium sulphide and if you like to a few drops of wetting agent.
 
There is many people that don't like this mixture because rodinal is a high accutance developer and you loose this feature with this mixture, they think if you want fine grain, just use a fine grain developer. I have not tried this mix yet. however it is possible that gives an interesting texture.
