RO9 special/ Studional three months on.

Out of date Fomapan 200
Another month on and I'm back to using the turquoise Studional and a further cutting from the Fomapan 200, only this time there are couple of dozen images to muck up. The chances of something going wrong diminishes as you get used to the way the developer works, the only spanners are out of date film and senior moments, if it all go's wrong I may learn my lesson.

So far the developer has been used seven times without it missing a step. When comparing the negatives with the naked eye or in this case a magnifier the density between the batches looks to be identical. As far as the compensation factor is concerned this is uncharted territory for me. The question is, does 20% allowance still apply two months on? Thinking on it carefully the answer is yes. My reasoning is that to increase it without knowing whether the suggested compensation worked or not does not make sense. I should test the information and not do my own thing.

The information on this developer states that once it is diluted one litre should be good for three months or 12 film processes which ever you arrive at first if stored properly. I will admit that the bottle this is stored in is to big leaving an air gap that will allow the developer to deteriorate more quickly according to the data sheet. I have not done this on purpose I didn't have a container the right size and yet it still works well. Obviously it is better to do what manufacturer recommends to get the best results but in the real world we all make compromises. So is it such a surprise that I'm getting good results? The real test will be at four, five or six months after dilution.

 I processed the negatives as previously mentioned and the results are just as good so much so that I also developed a roll of Agfa APX 100. It just so happens that the dilution for this film is 1+15 (the same as HP5+) or 1+31 for 4 and 8 minutes respectively at 100 ISO. With the 20% adjustment added it took all of five minutes in the developer to receive another set of good looking negatives.
 
The more I use this developer the more impressed I am with it.


 The table below shows ten popular film that use the 1 +15 dilution. The ones marked with * are the ones I have had good results with at the suggested times with the compensation added.

The double ** is my suggested time for this film at this dilution.

Black developer!?

I have gone back to using 35mm film, in so doing I have resurrected an old and long running project of portraits. I have never been backward in coming forward to ask people I meet if I can take their picture. When asking my chosen subject I'm polite and friendly with a little charm. It is not often that I receive a straight rejection. I've noticed that it tends to stop people for a moment, at which point I tell them it's a film camera. It appears that this is a reason for them to say yes when chatting with them.

This new interest in lugging my Nikon F5 around with me has also reunited me with a long time favorite film Agfa APX 100. I cannot remember exactly the last time I used this film but I do know it was back in the days when I regularly used ether ID11 or PMK Pyro. I still have both these developers on the shelf in powder form. Which led to a bit of a dilemma once the new roll of
APX was ready for developing. Should I make up a new batch of these old friends to keep the look of the negatives the same or go with the current ones???.
                                                        

I chose to go with RO9 partly because I wanted to see what sort of negative it would produce with the APX.                                                                      
Agfa APX  negatives developed with
RO9 special.
Before starting I made up a litre of fresh stop, fix and 300 mls of developer. I processed the film for the suggested thirteen minutes. The time counted down, as I poured out the developer, I was shocked to see this black liquid fill the measuring cylinder what the Hell! My first thought was that all the emulsion had come off, stupid I know but it always interests me what thoughts come into your head when things take you unaware. Needless to say that when I looked at the negs after they were fixed, all was OK. The negatives are nicely toned. I am not sure yet how grainy they are as Ro9 tend to be more grain than ID11.




It's just another colour to add to an increasing list of used developers.
