|
|
Hello,
Having recently begun my 4X5 photography, I've found that it is fairly expensive to experiment and testing. Managed to procure a 120 Roll Film Back to use 120 film at 6cm X 6cm. Trying Caffenol-C-M recipe I found online to develop the film and then digitize by photographing with a DSLR.
Regarding the developing, my negatives are very dark. Is this a problem with the developing times, proportions of ingredients and temperatures or an exposure issue. I use a Gossen Pilot light meter and it has seemed accurate over the years.
Appreciate any ideas. |

What film are you using? If you search, you'll find lots of posts in re: Caffenol. I never heard of this method, so can't comment.
I used Ilford XP2 Super chromogenic B/W film and had it developed at the local camera store in C-41 color chemistry.
A scanner with transparency lid and negative holders (see Epson) will give better results than copying the negs with a DSLR. |

Hello,
The film I am using is Kentmere Pan 100 B&W. It is from my understanding a less expensive Ilford film. Again from my understanding Caffenol-C-M is a version of the caffenol recipe reputedly tested to work better for medium ISO films like the Kentmere ISO 100. The recipe and times where in an acceptable range for that film.. I am newbie enough to follow directions and not yet understand the complete process. I've never heard of chromogenic film... Will look it up! My decades old Epson Perfection scanner decided now to expire. So the best I have available is my Nikon DSLR. I am testing my equipment, procedures so perfection is not necessary yet.
Processed a roll last night and left it in the salt bath fixer overnight, after checking it after 2 hours. It appears to be noticeably (less dark) with the overnight fixing. Checked the site and the web on caffenol and haven't identified and answer. |
