The recipe for low speed films

My successful recipe That I gleened fromt he you tube video in the blog post below with some tweaking that I have done

Woosang's tweaked Caffenol recipe with thanks to the person who posted it on youtube,

Set up.
Processing Tank (Of course)
3 glasses (any size)
3 spoons or more
Measuring jug X 2 at least 500ml
Thermometer
2 stop watches or as I uses an interval program set up for one minute intervals for 20 minutes
Bottle Opener (If you are tackling 35mm canisters)
Scissors

Ingredients
Have these laid out and ready

6 teaspoons of instant coffee (NOT Decaf)
1/4 teaspoon or 1000mg of Vitamin C. Tablets are OK but crush them first
3 teaspoons of washing soda (Wear gloves here)
350ml water at 20C (68F)
Extra water at 20C (68F)or have a tap that you can adjust to 20C (68F)
Fixer I used Acu from Paterson. 50ml mixed in with 350ml of 20C (68F) water
Hardener (optional) mixed into fixer

Liquid soap mixed in water Don't make it frothy

In the dark
I hate Film changing bags so make sure you practise putting the film on the reel first. Find a dark room and then hide under a blanket. If you can use a film changing bag, use that. (I find them too restricting. It is vital you practise first or you will be fumbling in the dark with unfamiliar equipment. Practise loading the tank too for the same reasons.



1. Open the 135 (35mm) canister wit the bottle opener. Use the flat end.



2. Cut the tongue off (The leader) and snip a tiny bit off the edges to aid in loading. (Only a little snip to make the edges smoother for loading)

3. Engage the film on the spool and using a twisting motion walk the film onto the spool (as you have practised this in the light ou know what I mean) If you have not SHAME I did warn you!
Cut off the core and finish the winding

5. Load the spool into the tank and seal

In the light





1. Measure out the ingredients into separate glasses and measure your 350ml (first lot) of 20C(68F) water. Add water to the glasses making sure each ingredient is disolved properly. You may have to heat the water a bit more to achieve this but allow the water to cool back to around 20C (68F)
(Enough Vitamin C goves the brew a greeny tinge)


2. In a big measuring cup (500ml or more) tip the contents of the glasses together, mix and then let stand for 5-10 minutes to clear and micro bubbles.

3. Set the stop watches to 1 minutes and the other to 20 minutes (for Lomo 100 film or Ferrania 100 film this should work for all films but you may have to adjust times as you get beter at this)

4. Pour in the caffenol mixture and at the same time start the stop watches. (As I said I used a training interval timer so it squawked at me every minute but whatever works for you) Agitate SLOWLY (and i Mean SLOWLY turn tank over count to 3 turn back repeat) for the whole first minute . Stomp the tank on the bench after each agitation.

(NB more agitation increased fog significantly. And increasing fog is not the same as speeding development. SO go SLOWLY )

5. Slowly Agitate (As described above) every minute 3 times for the next 20 minutes and don't forget to stomp.

6. After 20 minutes pour out the developer and quickly add 350ml of 20C (68F) water. More water is better. This is to flush the developer and it called a stop bath. We are keeping this as chemical free as possible.

7. Agitate 5-6 times and pour out. Repeat 3 times with fresh water (At 20C/68F roughly.)

8. fixer our chemical step. Tell the kids you will do this one step for them. Keep them away from the film chemical. Its a bummer that we need this step but without it, the film cannot be exposed to light. It is here you can add 25ml of hardener if you want to)
For ACU I used 50ml of fixer in 350ml of water (20C/68F) For fresh fixer 5minutes agitate 3 times each minute and don't forget to Stomp after each agitation.

9. pour out the fixer (Into a bottle, you can reuse it)

10. return to the kids.. Final Washing FYI Water is room temp here I didn't fuss about its temp, just not hot eh?

Water 3X agitation pour out.
Water 6X agitation Pour out
water 12X agitation pour out.

11. Water and liquid soap. Pour into the tank and agitate 24 times. SLOWLY not trying to make a heap of froth.

12. Pour out, open your tank and remove the spool. Walk the film off the spool, I have it attached to a peg and hanging as it walks off the roll. I squeegee with a squeegee but you can use your clean fingers..

13. Allow to dry over night, The opaque parts will clear and you should see lovely photos. :-) The waiting will kill you.. I know I keep going into the room to watch the film dry...



Success!!!
