things "develop" more and more. Today I got a message from Gerald (Nashville, USA) about successful developments of the Efke IR820 in Caffenol-C-L. To be honest, I've seen some really ugly pictures (from a technical point of view) with this film souped in Caffenol. Gerald demonstrates impressively what's possible. WOW! Also you might want to have a look at his magnificent flickr stream:

Here's what he wrote:
"These images were taken with a Yashica Mat 124G loaded with medium format Efke IR 820 film. Exposures were in bright sun at f-16 for 1 second on a tripod, using a Hoya R72 deep red (infrared) filter, making the effective exposure index about iso 3.
The film was processed in a daylight tank using Reinhold's Caffenol-C-L recipe without modification for a 70-minute stand development at 20 degrees celsius after a 5-minute presoak in distilled water. Initial agitation was for 45 seconds (about 12 inversions) and then I did not touch it for the rest of the time. I used a plain water stop bath and Ilford Hypam to fix.
My source of sodium carbonate (washing soda) was Spa-Kem pH Plus (100% sodium carbonate) from Kem-Tek (http://www.kem-tek.com). I used crystalline ascorbic acid and Folger's Original Instant Coffee. The potassium bromide came from Photographer's Formulary.
Thank you very much, Gerald, for the detailed explanation, the supply sources and of course the beautiful pictures. I'm really proud I can post this report here.
BTW, I'm not related in any way to any of the merchands, producers etc. mentioned here on my blog. This blog is and always will be free of advertisements as long as the hoster supports that. I don't sell my soul ;-)
