Coffee Break – Develop Film at Home with Caffenol

Guest Blog by Darren "Pancho" Riley

I'd read on Flickr about something called Caffenol. Fancy name, sure, but it's basically just instant coffee, washing soda and water. Some people add Vitamin C. And this Caffenol stuff can be used to develop black and white film or colour film as black and white. My experimental side was awakened and my thrifty side was even more excited so I decided to take the plunge! Here's what I did.

I had a roll of expired Solaris brand C41 colour film - only 12 shots so I figured I wouldn't be losing much in the event of my Caffenol experiment not working. Using my changing bag I loaded the film into a developing tank and then prepared the required ingredients. I used:

6 tsp instant coffee
3 tsp washing soda

Each was mixed in 125ml of water (125ml plus coffee and 125ml plus soda) and then the two were put in a jug with an extra 100ml of water. I put the jug in a warm water bath until it reached 20 degrees C and then poured the mixture into the tank.

The tank was agitated (turned upside down and the right way up again) for a minute and then agitated 4 times every 3 minutes. I did this for 25 minutes.

I then poured the non-toxic mixture down the sink and rinsed it with water, 5 times. This stops the developing process. Fixer was then added (this is the only “real” chemical you'll need) and agitated 4 times once a minute for 3 minutes. The fixer was then poured back into the bottle for reusing.

The film was then washed by pouring water into the tank, agitating 5 times, emptying then refilling agitating 10 times, emptying and finally agitating 20 times. I then put a little wetting agent into the water, removed the film and hung it to dry for around four hours.



I have to say, I was pretty pleased with the results and one of the shots (above) is a personal favorite of mine - a sleazy adult magazine store (and no, I haven't been in!). Considering the film was expired, was meant to be colour and was developed as black and white in a bizarre mixture of coffee and washing soda, I think the results were pretty good.





It's not the sharpest of processes but for someone like me who likes grungy photography, it's a process I'll definitely be investigating further. It looks like adding the Vitamin C can speed up the developing process a little when using proper black and white film but I can't say for certain - it's all about experimentation!

So get yourself some cheap instant coffee, some cheap washing soda and give it a go!

These sites were inspiring and very helpful to me:

Developing Black & White Film at Home

Guest Blog by Darren "Pancho" Riley

Since there has been a bit of discussion about home developing on the Film Photography Podcast recently (episode 25 / January 1, 2011), I thought I'd share with everybody how I do it. This is mainly because when I started looking into it, everything seemed so complicated and I needed something simple.

Also, it's difficult to say in a few words on a podcast how to do it without making it sound either too simple or too difficult, so whilst I appreciate (FPP Co-Host) Duane Polcou's segment on the podcast and very much look forward to more, I thought I'd try to help out those who've never done it before.

Please feel free to add your own methods, this isn't just developing the Pancho way! I'm not gonna list all the gear you ned here, but it will pretty much all get mentioned within the text. Here we go;

Put the roll of film onto a spool and put it into a developing tank. There's a great video here telling you how to do it and what you'll need - www.youtube.com/watch?v=6P9bNcBE_Hc - he's a funny, strange guy. Entertaining.



Right, you've got your film in the tank, it's ready to develop. Now you need your chemicals. Pre-mix some developing fluid, some stop fluid and some fixer. The instructions for diluting will be with the chemicals. For example, when using Ilfosol 3 I dilute it 1 part fluid to 9 parts water. Just read the labels, you can't go wrong. Put each chemical in a jug or reusable bottle and LABEL THEM! You can reuse the stop and the fixer but not the developer (not my way anyway).

Make sure your developing fluid is at around 20 degrees C. I just put the fluid in a jug and then put the jug in a bath of hot water from the kettle. Once the thermometer reaches 20 take it out and pour it into the tank (don't take the whole lid off, just the top part or open the access part of it - this will make sense when you've got a tank.

Start your stopwatch once you've fastened the lid back on, give it four turns upside down, tap it on the table and then leave it. Do this every minute for as long as it takes to develop.

"But how long does it take to develop?"

Easy. It'll probably tell you on the cardboard box your film came in. If it's Ilford it definitely will. It's as simple as that. If not, just use the Google!

Once you've reached the required time, pour the developer out - mine goes down the sink (if this isn't safe please do let me know!)

Now pour the stop in. This will only need around ten seconds but if it's longer it doesn't matter. Just give it at least ten seconds. Turn it upside down twice upon pouring it in and then ten seconds later, pour it back into your reusable bottle - NOT THE ORIGINAL CHEMICAL BOTTLE!

Now the fixer. This will need around 3 minutes, but like the stop, going over that won't harm it. Turn it upside down four times each minute. When done, pour the fixer back into it's reusable bottle. The film is now developed and can't be damaged by light. You're not quite done yet though.

Pour water into the tank and turn 5 times. Empty. Pour fresh water in and turn 10 times. Empty. Add more fresh water and turn 20 times. Keep this water in.

Add some wetting agent to the tank. I use Ilfotol but I hear washing up liquid is just as good. This helps the water run off the film without leaving stains.

Head to the bathroom, remove the film spool from the tank, remove the film from the spool and hang it over the bath. I use a couple of pegs and the cord from our venetian blinds. The cord is tied to the shower curtain rail and a peg hangs from that. I attach the film to that peg and the other peg to the bottom of the film to stop it curling back up. Give it around 4 hours to dry. 3 is sometimes enough and I've been known to give it just 2 and a blast of the hairdryer when I couldn't wait (that was more in the early days, I'm more patient now.)

Cut your film up, scan it and glory in the wonderful pictures you've created.

And that's it! I hope I've made it sound simple. If you're not sure there's a great video about the developing process here - www.youtube.com/watch?v=Vu0Ul_wsYO8



If you've got any tips to add or do it quite differently feel free to add and share the knowledge!

I wanted to share with you my experience getting started in home developing. While searching around and gathering supplies I found a "how to" for Diafine 2 part Developer. What interested me the most was the simple process and the ability to reuse the chemicals over and over again. The whole process involves 3 jugs, Diafine part A, Diafine part B, Fixer of choice (I use an Arista Rapid Type). Diafine is also very forgiving of temperature and film type. The chemicals at room temperature give consistent results and different types of film can developed at the same time. The developing contact times are the same for all B&W films. One exception is Fuji Acros where you double the contact times.

This developer has been perfect for me. The freedom to Shoot, Develop, and Scan independently is incredibly rewarding. I will add the link to the instructions I follow for reference.

Thanks for your constant inspiration.
