Snowy Highway - ISO 100 #H&W Control 13 minutes

Kodak 2238 shot at ISO 100 and developed in H&W Control 1:15. Underexposed and overdeveloped this is the first experiment. H&W Control was invented by Harold Holden and Arnold Weichert and “perfected” to work with Agfa Copex Pan Rapid microfilm which was rebranded by H&W as a house film to work with Control developer. The purpose of the creation was to use the high contrast film for aerial reconnaissance who H&W contracted with. Here I’m trying to see how high we could reasonable run 2238 as a standard film for snapshots etc. H&W Control’s patent states it’s normal initial use should be 1:15 dilution at 68 degrees F for 12 minutes and then expand from there. This roll was shot at ISO 100 then split. I developed the first half of the roll at 68 degrees for 13 Minutes and the second half for 14 minutes. Standard agitation is constant for the first 2 minutes and then 6 seconds every minute thereafter. Stop/washed in tap water at 68 degrees and fixed in Ilford Hypam 1:4 for 3 minutes (H&W suggests 2 minutes). These were shot on the same 2 days, overcast with little direct sunlight. The shots are obviously underexposed. But some of them are pretty adequate with some post process. There is a tendency for the picture to go dark and appear as evening or even well lit night. However it is easy to brighten the scene. After some thought I think the goal will be to get clear ISO 80 pictures on 2238. I will next extend the developing time in order to clear up some of the blocked parts. I may try some sodium thiocyanate something around 1 g/Liter of stock so 0.06 gram in the working solution.

    you know I have around 400 ft of hw control film. and some brochures from the manufacturer. I couldn't find an adequate developer for the film, but maybe you've found the recipe to make it? Mike, If you want me to send you some ofthe film to play with let me know and I'll mail it off.

    @heliossstardeath yes that's the formula off h&w's patent. It's working for a lot of stuff. I'd love to have some of the film to play with. I'll pay pal the shipping $ if that works.
