Bergger Pancro 400 development test.

Pancro 400 Developed in Rodinal & Caffenol C-L

Loading up my latest acquisition of a superb Nikon FA, with this new film Pancro 400, I headed off to the Melbourne F1 Grand Prix. It was a fairly sunny day so ideal for some photography. I used my 50mm Nikkor prime lens and a Nikkor 35-135 plus a T200 x2 extender for the long shots.

It has taken me a good 12 months to get my Caffenol developments working well. Whenever I have tried Rodinal I have always stuffed it up and have actually destroyed some rolls with it. So I have tended to stick with Caffenol to ensure a reasonable result. However I was concerned about using Caffenol with Pancro 400 as I could not find anything on the Net about this. Hence this experiment.

 In the black bag I loaded half the Pancro 400 onto 1 Patterson spool and the other half was left in the canister in the dark and later loaded onto another spool. The first spool I developed in Rodinal at the recommended mix of 1+25 timed for 8 minutes at 20c with agitation for the first minute and inversions at the top of each minute thereafter. Stopped in filtered water and fixed in Ilford Rapid Fix for the long 6 minutes as per the recommendation from Bergger inside the film packaging.

The second half roll was developed in my regular Caffenol C-L for 48 minutes at 22c (see previous post for recipe) and fixed in Rapid Fix for the recommended 6 minutes.

Here is a very interesting comparison where the film was cut in half. It was scanned as one so the scanner software may have favoured the Caffenol side more when it does it's auto adjustment to the film type. (there is no setting for Pancro 400 so I was using Kodak T400 mostly) Click to enlarge.






The Caffenol stand development has clearly brought out all the shadow detail in the clouds giving more depth to the image. I was impressed that my same recipe worked so well with the Pancro 400ASA film as I was expecting to have to modify it. Below are a mixture of shots from the roll in the two developers.

I am actually really pleased that I have managed to not stuff up developing in Rodinal and the results are very pleasing. It was also a quicker workflow. However I like how the Caffenol brings out all the shadow areas. Both processes seem to have worked very well with the Pancro 400 but looking over all the photos on my large iMac screen I tend to lean towards the Caffenol C-L for the best results. I might start using a paper filter when pouring the mixture into the tank. There are no white spots with the Rodinal but I can see a few with the Caffenol and the filter might stop this.

The Bergger Pancro 400 seems to be a nice 400 ASA film and the results are an improvement on my Ilford HP5 photos. But it is hard to go past the Agfa APX 100 or the Neopan 100 for the least amount of grain. At least now I am comfortable that I can safely develop the Pancro 400 in either method without a disaster as the film is too expensive to risk any failures.

Caffenol C-H success

After some rather grainy results with Caffenol C-L stand, Rodinal 1:100 and Rodinal 1:50 I thought I would try the Caffenol C-H recipe on a roll of film that I thought I had stuffed up. To my surprise this is my best result so far. Some of the shots actually have contrast and noticeably there is a lot less grain.

I am substituting the potassium bromide with Iodised Sea Salt at 10 x the amount so this would be 10 g/l. I also used the waterfree Washing Soda rather than the sodium carbonate which probably just gives the same result.

My next roll of film will be some 125 ASA to see if the grain is even tighter and I will use the same process or try the recommended Rodinal at 1:25.

Caffenol - First attempt

After reading many internet articles and sourcing suitable ingredients, I nervously concocted my Caffenol Stand brew and proceeded with attempting to develop a roll of film. Hardest part was getting the damn film onto the Patterson Spool in the black bag. (I have since watched a few youtube videos & now have the correct technique).

Well after 70 minutes developing, then washing and fixing, I was quite surprised that there were actual images on my negatives. The results were not too bad although according to my photographic adviser, they lacked contrast and a bit grainy. Hmm, well I have since learnt that Stand development does wash out contrast (which apparently can be recovered post processing) but on the other hand is totally forgiving on film speed as the developer will only develop the light areas so far and then slowly works on the dark areas. So on a single roll of film one can shoot at 400ASA and also shoot at 1600ASA yet the negs will still turn out okay.  My thought is that this is like turning the potential of a film camera to that which a digital camera does automatically in low light. I have yet to fully test this out but have switched between 400 and 800ASA on one roll with not much difference in the end result. Don't take anything I say here as gospel as I am only just a beginner in photography and just passing on what I have researched.

The shots below are from my first Caffenol roll. The river shot was scanned as a colour RGB. Realising my error later I rescanned the Mercedes in Monochrome.
