FP4+ developed in PMK Pyro method update

Zero camera, FP4+ developed
in PMK Pyro

The first permanent change is to go from two inversions every twenty seconds to one every fifteen seconds which is a reduction of two per minute. When I did this I wasn't sure if this would make the density of the negative less, as it turns out it has increased it, making for better toned prints. My conclusion is by decreasing the time between each inversion the developer in contact with the film surface is fresher for longer hence the increase in density.

I have also used an after-bath  (only with 120 FP4+) which does change the colour of the film base and seems to make them easier to print and at a softer grade. It has been suggested that the bath can reduce the sharpness of the negatives. Is this reduction noticeable? That's an answer you will have to find for yourselves as  I have only been using it so far with the film that's been exposed with the Zero pinhole camera, which is not known for it's ultra-sharp negative production. I will not be introducing it across the range of other makes of film I develop in PMK. I'm happy with the fine toned negatives it produces and see no reason to add the bath.

Those of us who like to go against the mainstream will use it for creative or pictorial purposes but you need to be sure that the grain is sharp across the negative, it may add that extra something you are looking for to the final photograph.

Deliberate distortion.

The enlarger is not there just to correct distortion but to add it as a compositional tool, in some cases to comic effect. The most obvious way of producing this is to bend the paper by clamping it between two blocks in a convex or concave shape. Double curves are possible. Remember the effect  aperture has on the depth of field and allow for it by using a larger F number to compensate and don't lose sight of the fact you will need to use dodgers to adjust the relative exposure.
