Rodinal or Pyro which will I use.

I was first introduced to Pyro by Trevor Crone when he mentioned it in a post on the film and darkroom users forum a year or so ago. I purchased a packet of the developer shortly after from my favorite supplier Silverprint. It has sat on the shelf gathering dust waiting for a suitable project.
The worst weather in over a hundred years postponed my trip into London to stock up, leaving me without any of my default developer Ilford ID11. The deluge of snow had revived a project started in the last snows at the beginning of 2010. I was starting to build up a back log of exposed film. I like to develop used film straight away. I had two developers on the shelf that could produce enough developer for the job, Rodinal or Pyro, I plumped for Mister Hutchens PMK pyro partly because it was a staining developer and it may bring something extra to my pictures of the snow.

Drying agent?

This is the final thing you do before hanging up your negatives to dry. This helps with the drying process by reducing the water tension allowing it to run more freely and minimising drying marks caused by the lime in the water.

Add three or four drops of wetting agent to the developing tank. Agitate the spiral in an up and down motion for a few seconds and leave for a minute. A further refinement is to add wetting agent to de-ionised water and transfer the spiral to it. Take the spiral out and peal the film from its grip or separate the two halves whichever you find easiest to do.
