CAFFENOL REBIRTH : WEEK 5 : SAME PLAYER SHOOT AGAIN

2020-22-iiic-4-16
Happy birthday Singapore

Processing film at home is a funny activity, actually it is a very modern one, inline with instant self rewarding of Instagram and phone-o-graphy.

National Day under surveillance

So after 4 weeks wit the same brew, I decided it was time for fresh coffee. I followed the same recipe but added some table salt, which is supposed to limit the fogging on the negative, specially for high speed film like the Ilford Delta 400.

I prepared the mix Sunday afternoon to be ready for processing in the evening, but actually I could not wait and loaded the finished roll I had in an improvised dark cupboard.

Feels like holidays

I realized that my expired fixer is now all grey and contains a lot of flocculation. I try not to poor the deposit in the tank, but did not think of filtering. I fixed for the usual 5 minutes. Then I filtered the fixer back in the bottle.

It looked the film was fixed properly but there is some deposit in places. Next time I will filter before pouring and extend the fixing  time just to be safe.

So I used the new mix at 28 degrees for a bit more than 5 minutes. The result is OK, but I would say a bit over done. I cannot tell if the table salt had any effect (I put 10g for a litter of Caffenol).

This time I managed to squeegee the water from the film without leaving dust or hair and let dry in the bathroom. The negatives are thick but scanned ok as you can see. There are some marks due to the residuals of the fixer I think.

Her (distant) reflection

So this is a roll of Ilford Delta 400, supposed to be a fine grain film (compared to HP5), a bit cheaper than the usual TriX. The film lacks a bit of contrast  in my opinion.

This was shot with the Leica IIIC and Voigtländer 21mm F4. With the 21mm the subject is always so far away.

In which case you make friends, or at least you have to engage.

Social Distancing Ambassadors

I engaged the social distancing ambassadors, as I think they deserve to be remembered for their service to the community and that hopefully one day they will only be memories and we will look back at this picture to make sure this was not just a dream.

The shots around Marina bay were made by a very bright day and some are done at higher speeds for which I suspect the Leica III to be a bit lazy, hence the mild darker right side (or brighter left).

I included a few more shots back to my usual habit of burning film randomly.

Good looking lad

I am still not so good at hip shooting, it seems I constantly aim too high. Luckily I realized I am not the only one.

Coffee again

I am a bit better at pre-focusing and aiming from the eye level. Particularly with my VC 21-25mm finder.

I hope you enjoyed the reading. The next roll is not very far away.

Stay safe.

CAFFENOL REBIRTH : WEEK 5 : SAME PLAYER SHOOT AGAIN

CAFFENOL Re-birth.

2020-19-iiic-24

7 years after my last failed experiments I am back again toying with Caffenol to process my black and white film. Do not try to figure out why I do not use standard methods, I cannot myself.

This time again I have put all the odds against me, I found a box of 5 year expired Fomapan P fixer in the cupboard, I shot the Caffenol unfriendly Kodak Tri-X on the Leica IIIc with the unreliable Summitar 50 and the new Chinese meter offered by a friend (more on this later).

2020-19-iiic-20

The set-up

From my past experiments I have a kitchen scale and a Patterson cuve, and some weights to hold the film when drying. (I just had to buy a 4$ battery for the scale)

Testing the fixer

20200711_124226

I found this idea on the internet to test the fixer by taking a piece of unexposed film, I cut the lead of a new roll found in the box, and drop it in the fixer (not the developer just right into the fixer) and let it sit a few minutes : it should go totally clear if the fixer still work as they should. Mine did so I should be covered from that angle.

I used in the past a recipe for stand development, but today I will try the Caffenol-C-M, recipe, the first on the http://caffenol.blogspot.com website.

Testing the developer :

I planned to test the developer with one of the following two test cases, but actually after discussing with my assistant (my son), we decided that anyway we will not be able to resist trying the film whatever the result of the test is. Anyway here are the test cases:

  1. Test 1: once again I cut the leader of a roll and drop one into your developer and let it sit a few minutes then drop in your fixer and let it sit for a few minutes. It should turn all black.(as this part is generally over exposed), advantage is that you can use the lead of the roll you want to process.
  2. Test 2: use a piece of unexposed film, say, a few frames from the beginning of a fresh roll and make sure it’s loaded in the dark. Process as you should, you should see the frame numbers and DX codes along the sprocket holes develop and the unexposed frames should develop to be clear.

 

The process:

The chemicals:

20200714_174658

For one liter the recipe is to mix in order :

54 grams of washing-soda (Harm Brand 8$ for 1 kg)
16 grams of Vitamine C ( crap from Guardian 13$)
40 grams of instant coffee (Netscafe Classic 10$)

Time and temperature

This is the difficult bit, the original recipe gives 15 minutes at 20 °C for 100 ISO film. Digi

tal truth ( https://www.digitaltruth.com/devchart.php?doc=timetemp) helps converting this to my 28 deg average temperature for 6’44 @ 28 deg, for 100 ISO. ISO 400 should be shorter, but the same site gives you roughly the same duration. SO i settled for 7 minutes

Here we go

  • Pre-soak 5 minutes (this step is optional, but it is relaxing)
  • Pour the developer
  • Agitation first 30 seconds, then 3 times each minute.
  • Stop:

– Fill and invert the tank 5 times
– refill and invert the tank 10 times
– refill and invert the tank 20 times
– refill and invert the tank 30 times

  • Fix: 5 minutes
  • Rinse

– Fill and invert the tank 5 times
– refill and invert the tank 10 times
– refill and invert the tank 20 times
– refill and invert the tank 30 times with a drop of washing up soap

Results

  • the negatives are dense but images can be seen when back lighted and scanned with the Epson v800

Where it goes wrong

The problem often reported for Caffenol is that the chemicals are not reliable, for instance, my coffee is a mix of Robusta and Arabica, where the active compound is more present in the robusta, so 100% robusta would be better. My Vitamin C contains sugar and flavoring which impact is hard to guess.

Anything new?

Where to go from here

My film is over developed, so I already have some plans for the next roll : shorter time ( it was suggested to cut by 25%), or try the same recipe for a 100 ISO film, or cut the coffee.

Money wise

I can do 5 batches with my Vitamin C + coffee, with 2 films per batch. You probably have to factor in 0.5$ a roll for Fixer, 0.4$ for the soda, if you are discounting the water you will be around 3.5 to 4 $, definitely cheap. 5 rolls would cover the 7$ a roll I pay to the lab for processing, so if you like the result its worth trying.
