“Strong Coffee” 2015. Mamiya C330, Mamiya-Sekor 65mm f/3.5, Tri-X 400 developed in Caffenol straight scan, no enhancements. Messy, dusty, but it worked! π
If you’re in the blizzard zone and stuck home this weekend, I hope this will give you extra reading material π
I’ve been developing film for quite a few years and although I don’t consider myself an expert at all, I’m familiar with traditional developers such as Rodinal, D76, T-Max, HC-110, etc, etc.
One developer that I’ve heard about, but never tried till recently was a home brew called “Caffenol.”
This is a process where you use instant coffee, washing soda, and vitamin C powder to concoct a mix that actually develops film.
When I first heard about this years back, I laughed it off thinking it was a big joke. When I investigated further, I was totally shocked that you can develop film with instant coffee!
The photo above is a result of my first Caffenol experiment. Now I know it’s far from an award winning result, probably not the kind of result anyone wants, but to be honest with you, I’m just thrilled that it worked! π

A 100 percent crop of the above image. I am unsure why, but I am not getting the option to show the image full size as I used to have. I am trying to get to the bottom of this and will fix it, if possible. If you could see it, you would see the glitter around the glasses well resolved.
Above is a 100 percent crop of the original scan. I adjusted the contrast levels to better show the details. I was quite amazed that the result, while messy, actually holds a lot of details!
The image was shot in 2015 with a Mamiya C330 and a banged up Mamiya 65mm f/3.5 lens that I got for $23. The film was Kodak Tri-X 400 which is my go-to for an easy to develop, classic film.
If you search the web, you will find many fine examples from Caffenol connoisseurs who have posted results much better than this.
As I said, I’m no expert at this. The hardest part is finding “washing soda” so I made it myself by heating up baking soda, not certain whether I did everything right. Also in the darkroom, I made the mistake of turning on the lights when I didn’t have cover on the tank with film in it, allowing for possible light contamination.Β Something I’d never done in all the years that I’ve developed film. Because of these issues, I was even more amazed that it actually gave me something at all!
I am now eager to experiment more and to perfect this process. However, that would mean I would have to waste a lot of rolls of precious memories so I have to be sure that each roll I process with Caffenol is really “disposable” to me, so to speak.
If you haven’t tried this process, take a roll of film that you think you could part with and try it out. It’s a lot of fun and could potentially save you money from buying traditional developers. It’s quite a kick to take the instant coffee on your kitchen shelf and turn it into a film developer, it really is! π
Have a blessed day and I hope you stay safe in you’re in the zone of this major blizzard.
Best, Sam
Note: I’m not sure if I’m doing something wrong or something changed with WordPress, but people used to be able to click on the photos to see a larger version, but now it doesn’t give me that option. If anyone can tell me why, I would appreciate it!
hey Sam ! beautiful moment and result you got here !
about money saving – you save it on dev chemicals and waste to film that not always looks as you wanted when you exposed it π
thank you for this story – always pleasure to read you posts

Thanks Victor, appreciate your comments and suggestions! Yes, I’m willing to waste a few rolls in order to perfect this process. If I can, then I might potentially save money buying commercial developers. But it’s an experiment with a big “IF” π Many thanks!!
