A contact of mine at Flickr uploaded a photograph developed with the following developer: Caffenol CL for 600 ml : washing soda (50 % water) : 20 g, vitamin C : 6 g, Potassium bromure : 0,6 g, Instant coffee : 24 g; the photograph was taken with a Zeiss Nixe 1927 converted into 120, film was developed along 70 minutes at 20ºC, results look good, it seems Instant coffee and Vitamin C work fine together as film developer (the photographer has other samples in his Caffenol CL set): http://www.flickr.com/photos/photoyann10/6088218366/in/photostream Carlos --- Rollei List - Post to rollei_list@xxxxxxxxxxxxx - Subscribe at rollei_list-request@xxxxxxxxxxxxx with 'subscribe' in the subject field OR by logging into www.freelists.org - Unsubscribe at rollei_list-request@xxxxxxxxxxxxx with 'unsubscribe' in the subject field OR by logging into www.freelists.org - Online, searchable archives are available at //www.freelists.org/archives/rollei_list
