How well will RO9 Special/ Studional perform a month on from dilution.

Nikkormat FT2 camera
 The developer has been diluted for two months, it's time to see if there has been any degradation of the solution over those months. It was not my intention to put the developer on the spot by using an out of date film and then to pick a make of film that I find difficult to get good results with but the die had been cast by the fact that a film had been loaded into my FT3 some time ago and then promptly forgotten about.

Developer  has changed colour
So what happened? To start with as I poured the developer into the graduate it was a gorgeous turquoise in colour. This is the second time I have used this batch of Studional so I have not a clue what this colour represents, it was clear when it was fresh. For all I know this could mean that it is dead and buried and the best thing to do is pour it away. RIP. I carried on anyway no point stopping now. I need to know what the colour represents. Good or bad?

This batch of developer had been diluted 1+15 but according to the data sheet it should be 1+30 for Fomapan 200 processed for 12 minutes plus 20% increase for the age, as the table indicates. Seeing as I have not taken any notice of the indications this will not work I throw caution completely to the wind and cut the development time in half and add 20% which I ignored developing for eight minutes. What the hell!

Contact print Fomapan 200.


So what did you think happened? Well! Yes, you are wrong. I am astounded these are some of the best negatives I have made with Fomapan 200 they are crisp and punchy or should I say they have a very good tonal separation, producing some rich blacks as the photographs that illustrate this post show.

I should throw caution to the wind more often if the results are going to come good like this!
