Vintage film developer, Adox E10

Y Ernst Satow, in his 1960's book, "35mm Negs and Prints", references a film developer, Adox E10. Does anyone have information about it?

Could it possibly be Edwal 10?

Metol..............................5g
Glycin.............................15g
Sodium Sulphite (anhyd)....70g
Borax.............................10g
Water to make 1 liter

Adox E10 was Adox' universal developer (accutance developer think Rodinal) for films and plates. It was mentioned in an Astrophotography book from the 1962 as Universal Entwickler. ADOX-Mikropress was their finegrain developer

Finally, a voice of reason.

NO, it is not Edwal 10. The E probably stands for Entwickler (German for developer) in much the sane way as Kodak uses D for developers such as D-76. Usually the Edwal formulas as written as ED-10. The amounts of sulfite and Glycin are not the same. Close but no cigar.

Using these older developers with modern emulsions is a bit problematic. Will they produce good results. It would be up to the user to do their own testing. In addition Metol and Glycin do bot form a super-additive combination.

If you are looking for incredibly tonality, E10 is probably the best developer I have ever used. It isn't particularly sharp or fine grained, but man, the tones!

I never used E10, but E12, the one with PPD in it. Also gorgeous in the ways you describe. Anyway, don't mean to derail the thread...

I think we discussed E12 before on APUG Thomas. I love that stuff too. E10 is a little different though. E12 tends to emphasize the brighter tones (it can really cook the brighter tones) and has finer grain by quite a bit. E10 is a more gentle developer that has a wonderful luminosity in the midtones. Give it a whirl if you ever have the chems. I haven't used it for a few years, but I seem to recall replenishing it like E12. I wouldn't call either of them general purpose developers though.

I loved E12 for portraits, and I ended up shooting film kind of like slide film, aiming for highlights mostly, letting the rest of the tones fall where they may. I actually ended up using it for absolutely everything, just to prove that I could. Sometimes I'd block up highlights.

I checked my Database and don't have an Adox 10 formula.

The main Adox formula back in the 1960's before Dupont closed the company and sold the machinery & rights to make their products to EFKE was known as Adox Borax MQ. This is essentially a slight variation of Agfa & Orwo 44 (Agfa Ansco 17). It's the only Adox formula I've ever seen published from that era.

Adox Borax MQ

Metol 2 gm
Sodium Sulphite (anhydrous) 80 gm
Hydroquinone 4 gm
Borax 4 gm
Potassium Bromide 0.5 gm
Water to make 1.0 litre

This is similar to D-76 with slightly better sharpness, but development times must be increased by 10 - 20 %.

Geoffrey Crawley included this developer in his 1960/1 series of articles in The British Journal of Photography. This developer formula was used for testing the DIN speed of films. It gives full film speed, excellent tonality and improved sharpness (acutance) compared to D-76. It was sold and published as FR-2 by EFKE. I used this developer replenished for a few years and the resulting negatives were consistently better than D76/ID-11, I used to supply it to a couple of friends who used it in deep tanks in their commercial studios.

I only saw it once or twice when I was just strting out in Photography.

E10 came in Little 10ml Ampoules or in a 100ml Bottle. so it was similar to rodinal that way. the glass ampoules had a aluminium seal with a pull tab.

Came in a Little Styrofoam box with 10 ampoules, and an instruction sheet. The one bottle I saw was also done up nice with a depression in the glass in the shape of an ADOX logo.

I had bought a couple to try as that sort of size was convenient and at that point my testing was "It worked" I went back to the store I bought it down-town a couple of months alter looking for more and was told it was discontinued and that one of their regulars wanted any bottles that anyone had unused.

Edwat ED-10

Metol ...... 5 g
Sodium sulfite ..... 100 g
Glycin ..... 5 g
Borax ..... 10 g
Water to make 1 l

Use FS. capacity 8 to 12 rolls per liter.

Modern Developing Methods, Third Edition (Mar 1946), The Edwal Laboratories, p 29.

This is a general purpose developer and not an acutance one if used as given in the book. The sulfite content is too high to produce acutance.

It may have been like the Beutler High Acutance developer, that was sold in Ampoules by Tetenal as Neofyn Blue, later they changed the spelling to Neofin. High acutance developers were very popular in Europe after WWII, particularly in Germany where Adox were based. Most European companies made High Acutance developers, Ilford Hyfin, Johnsons Definol, Kodak HDD (never sold in the US), Paterson Acutol S etc.
