Hi, Is anyone using the neofin blue developer for Efke 25? If not what are you using? Can you share some insights into your results? What are you printing on? Contacts or enlargements? Any information is helpful since I'm starting down this path. Thank you.

I haven't used this in some time, but I think It was 15ml of HC110 add water to make 600ml. 6.25 minutes at 70 degrees.

Why Efke 25. It has a funky spectral response. Other than that it is an awesome film. Very contrasty and capable of up to 115 lines/mm.
I used it with Pyrocat HD with good results, but beware that this film has a great potential to build density in very short period of time which can make it (unless using diluted developer) hard to control.

I have made contact prints on Kodak Azo, but have no doubt it will also make an outstanding enlargement.

I hope that helps.

Good advice from Christian IMO.

I also develop Efke 25 (120 roll thru 8x10 sheet) in Pyrocat-HD with good results, but as Christian says, beware of rapid density buildup.

I primarily contact print on Azo and also make a few enlargements.

I have used EFKE 25 developed in Neofin, as well as pyrocat. All sizes from 35mm to 13x18cm. Printed by enlarging on diffusing (colour head) and condenser enlarger, as well as contacts on "ordinary" paper, POP, cyanotype, van Dyke, and salted paper.

Unless you want dual-purpose negatives, I prefer Neofin. I would rather make two negatives (if LF) and develop both in Neofin to different contrast than try to make a negative fit both VC paper and alt-process.

Chris, I used PMK pyro for a full year with Efke 25 in 35mm, 120 & 4x5 for enlarging. It is similar to Neofin Blau in that it is a staining developer which masks grain and in fact uses similar chemistry. Works very well for enlarging, not as well for contact printing on azo, because the general stain from PMK doesn't reveal detail in shadows cleanly in the thin areas.

I tried ABC pyro for contact printing and had a difficult time with contrast, density and generally fickle behavior, so I stopped using it. I was never able to get consistent results with it, but it certainly is sharp with respect to grain and shadow detail. I know why people use DBI with it now.

I've since settled on Pyrocat with the 1:1:100 dilution for both azo and silver printing for Efke 25. I would have to agree with Ole about a "dual purpose negative" not being the best choice. If you want a contact print on azo, do your film tests first, then re-do them for silver enlarging (unless you go the BTZS route). Make sure to match the paper's scale to the film's contrast, or you will be chasing your own a$$ in circles for a while with mixed results.

This is wonderful film, but it is quirky with respect to development times, temperature, concentrations and agitation cycles. You need to be very consistent for best results and do your homework if you are going to tame it and have it work for you. That having been said, it is great stuff for rendering metallic materials, portraits and a "few" other things. It builds both contrast and density rapidly, so exposure and development are crucial to understainding the limits involved. Still my favorite film in flat lighting or for showing off chrome with bike shots. It is every bit as forgiving as Velvia 50 in E6.

I guess that's a "senior moment"? Neofin Blau is not staining, and is very different from PMK chemically as well as in terms of the result. PMK is Pyro-Metol-Kodalk, while Neofin is (probably) Metol-Carbonate.

Neofin is known as an "acutance developer", meaning it gives large grain and high acutance. But what it does to the slower EFKE films is to give some of the best tonality I have seen on any film! Grain is not a problem with EFKE 25, nor is sharpness. So my recommendation is to go for the best possible tonality. And in the case of these films (25 and 50), there is nothing better than Neofin. Or try "Beutler's"...
