Efke 50 ISO

I want to know how to get the optimum result from Efke 50 ISO film can some one

give me the site name on which I can able to see the formule and can prepare my

self because where I lived in INDIA here nothing is available for B&W films.If I

get this kind of web address then getting chemicals is no problem.And how it

will react with D-76 0r Xtol of Kodak.

I've used Efke 25 for several times now, with rather good results. I suggest you mixing up some D-76. If it's not available, you can find a recipe quite easily. For example see this page:

For Efke 25, I've used D-76 1+1 9min for best results. You can find starting times for Efke 50 Massive Dev Chart as well:

I hope it helps you. Good luck.

Hi, I think you are talking about croatian Fotokemikas Efke. If yes please go to http://www.fotokemika.net/. Under EFKE you will find a lot of data. I hope it helps. Best regards Iztok

Hc-110 Dilution B five minutes (7 minutes gets you 100 with very little change in grain/contrast)

I've developed Efke/Adox 25, 50, and 100 in Xtol at various dilutions; it's a beautiful film. I'd

highly recommend Xtol or one of its homemade variants such as Mytol or PC-TEA.

These are just some sites I found interesting. One large format photograher uses WD2D+

a pyro developer with EFKE. The developer gives unmatched tonal seperation especially in

the highlights.

(a few sources for developers and chemicals) not formulas so much. A good book is the

Darkroom Cookbook by Steven Anchell and also the Film Developing Cookbook.

 

Ken Light http://journalism.berkeley.edu/faculty/light/ has used a Chrone-C additive to

his developer in the past. Not sure what he is using now.

 

What city do you live in India? I was just in Chennai and way up north in McCleod Ganj.

 

 

I know this is a lot of information. Hope it helps.

Are you able to obtain Rodinal where you are? I have used Rodinal in dilutions of up to 1:100 for beautiful compensation results with the 25 and 50 ASA films. And for normal development 1:50. The image below is of R20 (now sold as R25). The "R" being for roll film. I have the development schedule for this particular test at another place, but it was dveloped in Rodinal 1:100 for approx 18 minutes, with gentle agitation at 30sec intervals for the first few minutes, then once every 60sec for a few minutes, but for about the final 10 minutes, very gently only once every two minutes. The image shows a white painted wall which was in full sunlight. Unfortunately the scan of the print shows a sooty black shaddow just under the house, but this is the fault of my scanning, because the print shows detail there, as well as beautiful separation of detail in the brightest white areas. This image was virtually grainless even with considerable enlargement.

 

EFKE 25 and 50 ASA can deliver a huge range of contrast results in Rodinal of various dilutions and agitation cycles.

 

If you can get it, another Tetenal Emofin (from powder stock). This is a 2 bath developer, which is excellent.

 

EFKE also responds well to Pyro development.

 

I will try and get beck with more specific details, (and some better scans.) I had to experiment with this film, starting from scratch. So I set about testing a few rolls. I try to keep it on hand now all the time. It very useful for a wide range of applications.

Hi Abhinava,

despite the Efke/Adox are not identical the unchanged mixture like their ancestors the Adox KB15/17/20 Tetenal Neofin is still the developer "especially made for them". They are similar to what you will find as Beutler developer receipt at different web resources (Basically 1% Solution of Metol+Sulfit and Carbonate).

Note, this is not exactly a fine-grain developer (still at least as fine as rodinal), but gives a good tonality and high accutance for the films which were regarded to be super fine grain, when they where young.

Perfect if used with 120s or Large format, not the choice if "no-grain-prints" from 35mm are the goal.

 

Have fun,

 

Martin

Thanks everybody to guiding me.

I have been using Barry Thornton's 2 bath process with good results.

It is very forgiving of exposure variations and if you wish to

'push' you can increase the alakinity of the second bath for a bit

more speed. This EfKe 50 has a completely different film base

than the KB17 I used 45 years ago. It used to be crystal clear

(like Copal rapid) but isn't like that nowadays.

I tested Efke R50 for the first time today. I developed it in Rodinal 1+100 in semi-stand development. And added 2 centilitre with Sodium Sulfide in the deveoper. 18 mins at 20 degree celsius. I think i can get great results with this film in some picturestyles. But i will do more testing on the ISO and how much overexposure it can take. I will also test it in 777-dev, Xtol, d76 and Neofin developer.<div></div>
