efke 25 film base

[jhnyguitar]

i just shot and processed some efke 25. i shot the film outdoors at

iso 25 and processed in ilfosol (all i had) 1:9 for six minutes. the

results were less than ideal. i liked the resolution of this film.

however, i over exposed it. the next time i use it i'll shoot it at

iso 50 and use plain d76 1:1, photoimpex's recommendation.

i have a question regarding this film's base for others who have used

efke 25: is it normal for the base to be very pink? i got a very pink

film base that concerns me given the effect this color could have on

vc papers. is this usual for this film or should i suspect a problem

with my fixer?

Hi geoffrey,

sounds like a fixer problem to me. Didn`t test the 25 yet (still in the fridge), but the 100 efke shows no colour. (Minimum grey might result from development).

Gonna come back soon, when the 25 stuff is tested.

What format did you shoot: 35mm, 120, or sheet film?

i tried refixing a small piece of the film in freshly mixed fixer. by

the way, i'm using ilford rapid fixer 1:4. anyway, there was no

change to the color of the base. i tested my fixer to see if it was

still good and it's fine. don't know what to think. i guess i could

try a different fixe

okay, here's the response, in my words, from mirko at photoimpex: efke 25 comes on a clear base. thus the antihalo coating must be stronger. (the film does have an amazing amount of dye on it which i noticed during prewetting.) the film does have a slight pink cast, which mirko says is no problem. bleaching during reversal prossessing is the only way to get rid of this pink cast. interesting. i really like the film, by the way.

<p>I love Efke. I shoot efke 25, process and develop my stuff and yes I did get some pinkish film. But I also got perfectly clear negatives. I always use the same D76 - Kodafix combination. I suspect it's the temperature of the developer. I also shoot the Infra Red Efke. I got negatives which had a very strong yellow dye. I've tried using the Hypo Clearing Agent but yellow film remained yellow as pink film did. Again, I believe is the temperature of the developer and the agitation time.</p>

<p>Since this thread was begun 10 years ago it's possible - likely - that some Efke films have changed over the years. Film base, emulsion, sensitizing and anti-halation dyes, etc.</p>

<p>Anyway, the only Efke film I used much of was R100 in 120. Excellent film during the early to mid 2000s, but I haven't used it since. No problems with any residual tint in the negatives - it dried with that steely gray neutral finish we used to see in Tri-X and other films before more sophisticated sensitizing and anti-halation dyes were used. A pre-wash poured out bright aquamarine effluent. I used only Tetenal Neofin Blue or Rodinal, both of which seemed to strip out any remaining dyes from most films. Another factor might have been the very soft well water I had back then in my rural home.</p>
