Looks like some drugs (one particularly) started to fill not only my veins but also entire space around me ;) ... Let me explain however everything from the beginning. About a week ago i took a couple of photographs on paper instead of film. That’s my first attempt to paper negatives. It’s a modern version of “Calotype”, an old process invented by Fox Talbot in September 1840 in which photographic paper is exposed directly using large-format camera. Such a paper is processed in darkroom where it gives negative (on paper) and then final positive print by making contact print. Easy peasy ...almost ;)
I used Ilford Multigrade IV RC Pearl Deluxe paper (cut to 4x5 format) which is very simple to handle due to quite fast drying and being flat during that process.
In case of paper negatives speed (ISO) is about 6. Quite slow but still faster than wet plate collodion for example introduced about 10 years latter ;)
So photographs has been taken...
Here I can come back to my “drug story” from the beginning of this post ;D
I decided to give a try... Coffee development (again, haha) which obviously is equal to darkroom printing in this case ;)
Very different proportions than in case of film dev process..
250 ml water
2 tsp of washing soda
3 tsp of caffe
1 tsp of vitamin C
Of course everything can be adjusted according to required amount of liquid. I was processing my papers in 500ml.

Conclusions?
It’s a veeery slow process comparing to when I use normal chemistry. First shades of the image appears after about 3-4 minutes...then image was ready after about 10minutes (!).
As a comparison - week ago i took couple of photographs on the same paper and I processed them in Ilford Multigrade paper developer. They were ready in 1.5min
Anyway - I have negatives. Time to create proper print.
Mentioned before photograph taken week ago was presented on my Facebook page. This one was processed in Ilford Multigrade paper Developer (click
HERE please) and then inverted in photoshop to create positive. All looks great but Photoshop is not the right way.
Below is the other one created the same day... you know this photograph from my older post but it was taken on normal film back then ;)

I set my darkroom last night to process and print the other photograph taken yesterday (first image in this post).
Contact print is made by creating sandwich with clear paper and paper negative sticked together on emulsion side. Negative must be obviously on the top.
Exposure and hight of the lamp (enlarger head) is another crucial element in this process. It will provide differences in contrast of final image. I had a rather limited time so i could make just a 2 tests. One with 2 sec exposure and second with 4 sec. The last one was quite good but not good enough. Lack of contrast ...It only means I will have to come back to it ;)

Differences?
Big..it’s again depends on what you prefer. With paper negatives, traditional development gives quite strong contrast which usually I like. Coffee development gives however more details, nice brownish tint on paper but not enough contrast...
I am sure that something is not working here properly but don't know what. It may be soda again as in case of
Caffenol-C-L ...or something else.
Before i tried it I spoke to Damian Dzialoszynski , photographer who is experimenting a lot with these materials (click
HERE please to see his blog). His prints full of fantastic blacks and shades and generally great contrasts where ready after a few seconds... (???)
Will have to work it out definitely. Its all constant learning curve ...
If somebody who is reading this post had a different experience or some advice you are more then welcome to post it here or contact me directly. Thanks a lot!
