I kept putting it off as a &#8220;what&#8217;s the point&#8221; exercise. Well, after an encouraging discussion with <a href=\"https:\/\/www.gwenrileyjones.com\/\" target=\"_blank\" rel=\"noreferrer noopener\">Gwen Riley Jones<\/a> a couple of weeks ago, about less toxic processes, I thought I might as well give it a go.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">There are plenty of blogs, social media posts and YouTube clips of the process, many with mixed results, partly what had put me off for so long. Why bother going through he effort for poor weak flat negatives&#8230;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This evening after my first attempts, Gerald Figal, over on Facebook reminded me about the Caffenol Cookbook, available for download <a href=\"https:\/\/www.caffenol.org\/2012\/11\/27\/the-caffenol-cookbook-bible\/?fbclid=IwQ0xDSwKMiRJjbGNrAoyJDWV4dG4DYWVtAjExAAEemBTYhVqle1qeBsZoTThi5B5mJZRZv6rHgtM0nbYyXNqSkOXCqf3-ZLGw6XU_aem_Y6-3zeA6fLKvDiTUTmPdlg\" target=\"_blank\" rel=\"noreferrer noopener\">here<\/a>. I had downloaded it to my mobile ages ago and forgot all about it&#8230; better late than never. I&#8217;ll have a read tonight.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Anyway, back to today&#8217;s attempts. I always have spare rolls of film to test that have been thrown in a darkroom drawer, or still left to finish in some camera or another.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">I chose a roll of medium format Ilford Delta 400 which had been in the Koni Omega Rapid camera and a 35mm roll that was still in the Horizon 202 panoramic camera. Turns out the 120 roll was shot over two years ago and the 35mm started last summer.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"450\" src=\"https:\/\/fourtoes.co.uk\/iblog\/wp-content\/uploads\/\/2025\/05\/PSX_20250510_201307.jpg\" alt=\"\" class=\"wp-image-25425\" srcset=\"https:\/\/fourtoes.co.uk\/iblog\/wp-content\/uploads\/2025\/05\/PSX_20250510_201307.jpg 800w, https:\/\/fourtoes.co.uk\/iblog\/wp-content\/uploads\/2025\/05\/PSX_20250510_201307-300x169.jpg 300w, https:\/\/fourtoes.co.uk\/iblog\/wp-content\/uploads\/2025\/05\/PSX_20250510_201307-768x432.jpg 768w, https:\/\/fourtoes.co.uk\/iblog\/wp-content\/uploads\/2025\/05\/PSX_20250510_201307-520x293.jpg 520w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Most Caffenol recipes suggest the cheapest instant coffee available. I opted for Nescafe Classic, far from cheap, but high in Robusta coffee beans which apparently has more Caffeic Acid than Arabica beans. Worth a try, stacking the odds in my favour.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Ascorbic acid (Vit C) and Sodium Carbonate (Soda Crystals) I already have as they are used elsewhere in the darkroom. The ionised salt, to prevent film base fog in faster films, is found easily at the supermarket.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"450\" src=\"https:\/\/fourtoes.co.uk\/iblog\/wp-content\/uploads\/\/2025\/05\/PSX_20250510_201317.jpg\" alt=\"\" class=\"wp-image-25426\" srcset=\"https:\/\/fourtoes.co.uk\/iblog\/wp-content\/uploads\/2025\/05\/PSX_20250510_201317.jpg 800w, https:\/\/fourtoes.co.uk\/iblog\/wp-content\/uploads\/2025\/05\/PSX_20250510_201317-300x169.jpg 300w, https:\/\/fourtoes.co.uk\/iblog\/wp-content\/uploads\/2025\/05\/PSX_20250510_201317-768x432.jpg 768w, https:\/\/fourtoes.co.uk\/iblog\/wp-content\/uploads\/2025\/05\/PSX_20250510_201317-520x293.jpg 520w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">I don&#8217;t recall anyone mentioning NOT to add all the ingredients at once. I dissolved the coffee first with a little warm water then added the rest of the water followed by salt, Vitamin C and finally all the soda crystals. There was a steady eruption of foamy stinky coffee mixture from out of the jug. Glad I had it in a large darkroom tray. I wish I&#8217;d take a pic. Like a great big milkshake. Binned it and made another far more slowly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">10 minute development at 20 degree C. Continuous inversions for first minute then ten every minute. Washed\/stopped well before my standard Hypam fixer.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">120 roll film first. Not bad. I was expecting low contrast negatives.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"800\" src=\"https:\/\/fourtoes.co.uk\/iblog\/wp-content\/uploads\/\/2025\/05\/PSX_20250510_201349.jpg\" alt=\"\" class=\"wp-image-25427\" srcset=\"https:\/\/fourtoes.co.uk\/iblog\/wp-content\/uploads\/2025\/05\/PSX_20250510_201349.jpg 800w, https:\/\/fourtoes.co.uk\/iblog\/wp-content\/uploads\/2025\/05\/PSX_20250510_201349-300x300.jpg 300w, https:\/\/fourtoes.co.uk\/iblog\/wp-content\/uploads\/2025\/05\/PSX_20250510_201349-150x150.jpg 150w, https:\/\/fourtoes.co.uk\/iblog\/wp-content\/uploads\/2025\/05\/PSX_20250510_201349-768x768.jpg 768w, https:\/\/fourtoes.co.uk\/iblog\/wp-content\/uploads\/2025\/05\/PSX_20250510_201349-200x200.jpg 200w, https:\/\/fourtoes.co.uk\/iblog\/wp-content\/uploads\/2025\/05\/PSX_20250510_201349-520x520.jpg 520w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"450\" src=\"https:\/\/fourtoes.co.uk\/iblog\/wp-content\/uploads\/\/2025\/05\/PSX_20250510_201335.jpg\" alt=\"\" class=\"wp-image-25428\" srcset=\"https:\/\/fourtoes.co.uk\/iblog\/wp-content\/uploads\/2025\/05\/PSX_20250510_201335.jpg 800w, https:\/\/fourtoes.co.uk\/iblog\/wp-content\/uploads\/2025\/05\/PSX_20250510_201335-300x169.jpg 300w, https:\/\/fourtoes.co.uk\/iblog\/wp-content\/uploads\/2025\/05\/PSX_20250510_201335-768x432.jpg 768w, https:\/\/fourtoes.co.uk\/iblog\/wp-content\/uploads\/2025\/05\/PSX_20250510_201335-520x293.jpg 520w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">The 35mm though was far denser, I&#8217;m unsure if it&#8217;s base fog or over development.

(I was reluctant to use FB just yet).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">My first thoughts on Caffenol. Yes it works, as proven by so many before, but is it really that much less toxic? Probably yes. I wonder if anyone has done any full on studies of coffee plantation, processing, packaging, shipping, repackaging and costs. The ammount of coffee, vit c and soda crystals used per film compared to my bottle of Kodak HC110, which will last me a few more years.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Especially when there are so may variables using Caffenol as a developer. My Kodak dev has been researched and manufactured to give controlled results. I guess the same could be done with Caffenol, with some patience and expense.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">I think I can see the appeal for experimental photography and expired film but not sure I&#8217;d want to rely on it for fresh film at today&#8217;s prices. Not until I can get repeatable consistent results at least.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Is it cheaper? Not by much I suppose. I&#8217;d have to try the cheapest coffee available and see what happens. Again it seems such a waste. I have read of people using used coffee grounds, but again how do you standardise that. And the use of fruit juices  wine, beer, beetroot, spinach and other organics instead of the coffee but again I&#8217;d rather use those products for eating and drinking. Amd if you can swap that out, how important are those in the development process? More reading is needed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">And the argument of being able to develop film in an emergency with household ingredients when you don&#8217;t have film developer&#8230; when is that going happen? Amazon deliver usually next day \ud83d\ude42 sorry being a bit flippant there.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">I would give Caffenol another go, but next time with fresh film and precise exposures rather than the sunny sixteen rule which these two rolls were taken with. So a bit of a more controlled test.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">And I would use it for experimental random results on occasion, maybe.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n","protected":false},"excerpt":{"rendered":"<p>This has been on my To Do list for far too many years.
