Survival scenario #117 :
You’re trapped in a grocery store. Zombies are closing in from all
sides. You have a crucial photo that could end the carnage, if only you
had some way to develop the film.
What do you do?
You grab some instant coffee and vitamin C, you develop the film, and you vanquish the zombies.
What, you don’t think we’re serious?
First of all, zombies are an inevitable part of life.
And secondly, you really can develop film using vitamin C and coffee . For reals.
Read on, and we’ll show you everything you need to know. Quick, before the zombies regroup!
How to Develop Film with Coffee and Vitamin C
via Found Photography
Okay, first things first: using coffee to develop film is not
something Ansel Adams would do. But it works, it gives your film a
distinctive look, and it has a certain MacGuyver-ish flair. Think of it
like using a plastic camera- it’s more about having fun than getting
technically flawless results.
With most film types, the results will be more contrasty and grainy
than regular developer. If you do this with color film (negatives or
transparencies), you’ll end up with black-and-white negatives.
Here’s the thing, though: different films will have different
results. Some will develop perfectly in 12 minutes, others will take up
to 20 minutes. Shoot a test roll of your favorite film, develop it for
12 minutes and see how it turns out. If it’s too thin, it needs more
time. If the negatives come out opaque, it needs less time.
What You’ll Need: Chemistry
Instant coffee (not decaf) Vitamin C powder Washing soda (see Step 1) 2 gallons of room-temperature distilled water (or tap water if you’re not fussy) Fixer A tiny wee drop of dishwashing liquid
What You’ll Need: Equipment
A daylight developing tank & reel A roll of exposed film A bottle opener Scissors Measuring beakers (including one large enough to hold 16 fluid ounces) Measuring spoons 2 glasses A spoon A timer 2 clothespins Clothesline or coat hanger
Step 1: Acquire Materials
Washing soda can be tricky to find unless you live in a rural or highly eco-conscious area. We found ours at Rainbow Grocery , but you can order it online ,
or call around to drugstores, health food stores, or pool supply stores
(it’s also known as sodium carbonate or soda ash). Baking soda won’t work as a substitute.
If you don’t have a daylight developing tank ,
look for a used one at photo supply shops or borrow one from a friend.
If you buy one, get one with adjustable plastic reels. Steel reels are
more trouble than they’re worth.
Step 2: Make the Developer
tank should have instructions about how much liquid it takes to fill
the tank. As a general rule, 12 ounces should be enough for a roll of
Formula for 12 oz. of developer:
12 oz. water 5 teaspoons instant coffee crystals 3 1/2 teaspoons washing soda 1/2 teaspoon vitamin C powder
Mix the vitamin C and coffee in a glass with 6 oz. of water. Stir
until all the crystals and gritty bits are completely dissolved. Mix
the washing soda in a separate glass with 6 oz. of water and stir until
Mix the two solutions together in a container large enough to hold all of the liquid.
So, we heard that this developer smells really bad, but we didn’t
believe it until we mixed the 2 liquids together. Holy frijoles! How
can things that smell like coffee, nothing, and nothing combine to
smell like grim death?
Step 3: Mix the Chemistry
Mix enough fixer solution to fill the tank, following the package
instructions. Set aside until you’re ready to develop the film.
In a separate container, dissolve a small drop of dishwashing liquid in enough water to fill the developing tank. Set aside.
Step 4: Set Up the Darkroom
film must be loaded onto the reels in total darkness. Ask somebody to
let you use their darkroom, or find the darkest room in your abode and
cover any windows with double layers of black garbage bags. Don’t
forget the cracks under and around the door. If light still gets in,
wait until dark to do this. Or use a changing bag .
Set up an area to load your film, like a desk or counter. Lay out
the reels, film cans, bottle opener, scissors, and various developing
tank parts in a way that will make them easy to find in the dark.
Step 5: Practice
If you haven’t loaded film before here’s how .
Practice a few times with a blank roll of film. Try it with the lights
on a few times, then with your eyes closed until you feel ready to do
it for real.
Step 6: Lights Out!
THIS MUST BE DONE IN TOTAL DARKNESS.
Pry the lid off the film can with the bottle opener. Cut off the film leader to square the end of the film.
Feed the film into the reel, turning first your right hand, then
your left hand clockwise, using your thumbs to guide the film onto the
Continue this motion until all the film is loaded and you reach the
end of the spool. Cut the film off the spool and give the reel an extra
turn or two to load the very end of the film.
Slide the reel onto the spindle (i.e. the part that looks a pipe),
and put it into the tank. Screw in the part that looks like a funnel,
and put on the rubber lid.
Step 7: Set Up the Chemistry
You can turn the lights on now.
You’ll need a sink for this part, preferably one that’s easy to
clean. A ventilation fan or open window would also be nice, but you’d
be OK without it. The chemicals are more stinky than harmful.
Get all of your chemistry ready next to the sink, put the tank in the sink and set the timer for 12 minutes.
Step 8: Developing!
Take the rubber lid off the tank and pour in the developer. Put the lid back on.
Hit start on the timer and agitate slowly and constantly for the
first minute. (Do whaaaat? One agitation equals turning the tank upside
down and then right side up again once.)
After the first minute, agitate the tank 3 times once a minute.
Step 9: Stop and Fix
the timer goes off, pour out the developer and fill the tank with
water. Agitate 6 times, then pour out the water. Repeat this step 2
Pour out the water or stop bath and fill the tank with fixer. Set the timer for five minutes and agitate 3 times each minute.
Step 10: Final Wash
out the fixer and fill the tank with water. Agitate 3 times and pour
out the water. Refill with fresh water, agitate 6 times and pour out.
Refill, agitate 12 times and pour out.
Refill the tank with the soapy water you mixed in Step 3, agitate slowly 24 times then pour out.
Open the tank and remove the reel.
Step 11: Hang the Film
Twist open the reel and remove the film.
Use a clothespin to hang the roll of film from a clothesline. If you
don’t have a clothesline, hang a coat hanger up in the shower and hang
the film from that.
Bring two fingers together on either side of the film and drag them
down the roll to squeegee off any excess water. Clip a clothespin on
the bottom edge of the roll to keep the film from curling as it dries.
Step 12: Enjoy Your Photos!
When the film is dry, scan it into your computer or get in the darkroom and git to printin’!
If you don’t have a scanner, you can send your film to a company like DigMyPics or ImageLab , or google “film scanning” plus the name of your town to find local businesses that will scan your film for you.

What To Do With the Leftovers
Dissolve the rest of the instant coffee in a bucket full of hot
water and soak your jeans in it overnight to get that worn-in tint that
Urban Outfitters charges extra $$$ for.
Washing soda makes a great eco-friendly laundry detergent and all-purpose cleaner.
Vitamin C removes hair dye without damaging your hair. Mix a
teaspoon of vitamin C powder with a tablespoon of shampoo, massage into
slightly damp hair and leave in for 45 minutes before rinsing it out.
It will tone down any dye job, but won’t completely remove stubborn
colors like red or black.
