Hi all!!
Mike,
To develop B&W negative films like Kahl 21 & 27 I´m based on processing tables of some Kodak films like Plus-X Pan 125 and Tri-X Pan 400, and works fine.
To develop Kodak Plus- X and Tri-X as negative films, Martin Baughmarten sent to me information on the matter (Thanks, Martin!)
All the films are processed wtih a spiral Lomo Tank:
To develop Kahl 27 (B & W neg. Film ASA 400)
Developer: Kodak D-76 (1:1); 10 minutes at 20ºC (68º F)
Stop Bath : 30 seconds (Acetic acid at 2% in 1 1iter of water)
Fixed: Kodak rapid fixer (5 minutes)
Wash (with current water: 20-25 minutes)
Final wash: Destillated water with some dops of Kodak Photo –flo: 2-5 minutes
To develop Kahl 24 (Reversal B &W ASA 200) As negative film (overexposed 1 f-stop, just like as ASA 100 negative film):
Developer: Kodak D-76 (1:1); 10 minutes at 20ºC (68º F)
Stop Bath : 30 seconds (Acetic acid at 2% in 1 1iter of water)
Fixed: Kodak rapid fixer (5 minutes)
Wash (with current water: 20-25 minutes)
Final wash: Destillated water with some dops of Kodak Photo –flo: 2-5 minutes
To develop Kodak Tri-X as negative film overexposed 1 f-stop (ASA 100): The same process for Kahl 24 ASA 200 reversal film.
To develop Kodak Plus-X as negative film overexposed 1 f-stop (ASA 25):
Developer: Kodak D-76 (1:1) 6 minutes at 20ºC (68º F)
Stop Bath : 30 seconds (Acetic acid at 2% in 1 1iter of water)
Fixed: Kodak rapid fixer (5 minutes)
Wash (with current water: 20-25 minutes)
Final wash: Destillated water with some dops of Kodak Photo –flo: 2-5 minutes
To develop Kahl 21 (B & W neg. Film ASA 100)
Developer: Kodak D-76 (1:1) 7-8 minutes at 20ºC (68º F)
Stop Bath : 30 seconds (Acetic acid at 2% in 1 1iter of water)
Fixed: Kodak rapid fixer (5 minutes)
Wash (with current water: 20-25 minutes)
Final wash: Destillated water with some dops of Kodak Photo –flo: 2-5 minutes
The Kahl stock (In 60 meters cans) costs about € 29,00 + sending. See their Web Page:
http://www.kahlfilm.de. Just click SHOP and then click Filmmaterial and select Super 8. If you want to buy 60 mts. of film cans, select Meterware. (But you will need to use reloadable casettes).
To know how to processig film with a Lomo tank I recomend you to read an article signed by Martin in His Web Page (The 8mm format Metadirectory) Very recommended Page!:
