Agfa-47

[Relayer]

Hello

Old and forgotten developer from Agfa

Metol 1.5g
Sodium Sulfite 45g
Sodium Metabisulfite 1g
Hydroquinone 3g
Sodium Carbonate 5g
Potassium Bromide 0.8g
Water 1l
pH=9.6

Have ~1.5x more speed than D-76. Starting dev.time 5-6min. Produce negatives with normal contrast and great sharpness.

Kodak Double-X @250 in Agfa-47 5min

Ilford Surveillance P3 200 @200 Agfa-47 5min

I wouldn't call myself an expert on MQ developers but from looking at its formula there is nothing that suggests it would gain 1.5 stops over D-76. Care to explain how a developer that looks like a mixture of D-76 and D-25 can give so much higher emulsion speed?

 

[AgX]

Relayer stated to have 1.5 times more speed. That does not mean 1.5 stops more.

 

[Relayer]

1.5x more speed = Agfa-47 need 1.5 times less time than D-76 for developing film to same ISO. In case Kodak Double-X @250 - 7.5min in D-76 and 5min in Agfa-47. I guess that 7.5min in Agfa-47 will be good for 400 ISO, but contrast may be very high and not acceptable - I can't test this combination.

 

[Relayer]

In Anchell it is listed as Ansco 47 and is described as giving somewhat higher than normal contrast, good for use under low contrast or controlled lighting conditions.

Yes, negatives look like slightly more contrast than usually I have. Probably decreasing amount of Hydroquinone to 1.5-2g/l will decrease contrast.

Hello,
this is not the formula for AGFA 47, ANSCO 47 may be correct. The original AGFA 47 is an amidol developer.

I found formula here: http://www.digitaltruth.com/data/agfa_ansco_47.php
But in some books I found that Agfa-47=OWRO-47 is amidol print developer. I think this isn't correct because in Dead Link Removed from 1938 this formula listed as Agfa-47. But ORWO-47 is amidol developer

Hello,
my AGFA book about "Photochemikalien" has been written in 1952 by E. Schloemann and in this book AGFA 47 is an amidol developer.

Hello,
my AGFA book about "Photochemikalien" has been written in 1952 by E. Schloemann and in this book AGFA 47 is an amidol developer.

In 1952 the East German (DDR) company VEB Filmfabrik Wolfen was still using the Agfa trademark, as was the West German Agfa company. (Wolfen changed to the Orwo trademark around 1964). So is this a case of the East and West "Agfa" companies using a different numbering system?

No, the confusion is because Agfa Ansco in the US used different formulae numbering to Agfa in Germany.

(Agfa-) Ansco 47 MQ is very close to Kodak 61a, superb gradation, very sharp, but usually grainy. I was surprised by the small grain you get with XX.

 

[Relayer]

you right, Agfa-47 equal to D-61a 1+1

 

[Ian Grant]

you right, Agfa-47 equal to D-61a 1+1

Not breally, it's more like D61a is Agfa Ansco 47 with double the level of Sodium Sulphite. quite different.

Kodak D61a Stock:

Metol 3.1g
Sodium Sulphite anh. 90g
Sodium Metabisulphite 2.1g
Hydroquinone 5.9g
Sodium Carbonate anh. 11.5g
Potassium Bromide 1.7g
Water 1l

Kodak D61a 1+1 / Agfa-47:

Metol 1.55g / 1.5g
Sodium Sulphite anh. 45g / 45g
Sodium Metabisulphite 1.05g / 1g
Hydroquinone 2.95g /3g
Sodium Carbonate anh. 5.75g / 5g
Potassium Bromide 0.85g / 0.8g

It's the same thing if you consider that 5 gr. Sodium carbonate anhydrous = 6 gr. monohydrated

 

[Ian Grant]

I have to admit I was comparing to the Agfa Ansco 47 R - replenisher

When it comes to processing chemistry Kodak lagged way behind their competitors for many years only really bringing out innovative products with HC-110 and Xtol.

[Relayer]

Harold, Agfa-47 use 6g Sodium Carbonate monohydrate = 5.1g ahydrous. so D61a 1+1 use by 10% more sodium carbonate than agfa-47. I think that this isn't very important

 

[Ian Grant]

Just to be clear this is not Agfa 47, that is an Amidol developer, and that is very important.
