R09 + 1hour stand = high base fog

[morback]

Hi,

After finishing my last bottle of Agfa Rodinal I went on to buy R09 One Shot from Freestyle. As far as Freestyle is concerned they say to use it exactly the same as Rodinal. The label has the same dilution and times as the Agfa bottle (as far as I remember).

Thing is, 1:100 for one hour in Agfa Rodinal yields beautiful negs, but the same recipe with R09 give me really high base fog that seems to recede in drying phase.

3 rolls went thru this process:

1st tank had Arista Premium and Foma 200 (Arista came out usual, Foma high base fog)
2nd tank had Fuji Across and had the same fog as the Foma film...

Anyone noticed anything similar? It looks to me as though this is more concentrated than the Agfa stuff...

This guy, really, knows his stuff. I'm not sure if he is a member here, but he is extremely knowledgeable. Here is his take on part of your question.

Maybe not fog in particular, but you will see what he says.

Thanks, I should ask him directly. The R09 I am using though is not Fomadon, but Compard R09...

The mismatch is old R09 and the new Rodinal name R09 one shot.
Compard (they are filling up the chemicals) is affiliated to Rollei-Maco who is doing the distribution for Rodinal (R09 one shot). And I can assure you that in the R09 bottle is exactly the same chemical stuff from the old Agfa plant in Vaihingen-Enz in Germany.
So there must be another reason that you can not reproduce old results. The only way to check these things out is the same reference way in working method and a densitometer for reliable results.
From my own results I can only report that the 125ml content packing for Europe gives exactly the same results.
The change in name has everything to do with the Agfa brand and licence of the Rodinal name. Unfortunately very confusing for customers what is going on. But the most important thing is that Rollei-Maco can guarantee that the same chemical content is in that (Rodinal) bottle.

Fotohuis, again you lived up to your reputation. Thanks for jumping in, I could not remember where I saw your posts. I have to say that there are a (very) few of you very knowledgeable photographers from everywhere that have been generous and an inspiration to me, and I'm sure many others, THANKS.

As an aside, this is good to know, as Canada is now using Blazinol? as a name for Rodinal. And I'm sure that it may have a confusing name change in the USA.
