Bergger PMK Film Developer, A & B 500ml plus 250ml

Product Description

PMK is a unique, 2-part universal film developer.

The original formula for PMK was created by Gordon Hutchings, to be able to process as many modern films, with as wide a range of shooting conditions, as possible. Now Made in Germany, it exhibits the following characteristics in use :

• Great sharpness.
• Very fine grain.
• Yellow staining (Pyro) of the negative. Pyro is often perceived as offering the best quality result ever for processing a negative, but staining intensity depends on the reduced silver quantity.
• Very low fog.
• Stability of the stock solutions.
• Process repeatability.

When processing, we suggest using an alkaline fixer, like our Softpack RXN, to obtain the best negative stain, and the best stability in time. A water stop bath may also help is keeping the stain.

PMK's two-part solutions have a very long shelf life if they are not mixed. This, and the fact that you can process practically any modern black and white film makes it a perfect choice for knowing your film developer will work for your film choice.

You get two bottles - 250ml and 500ml and in standard dilution (1+2+100), the PMK kit will make 25 litres of working solution.

For Jobo rotary processor users, we recommend the Roto additive for PMK to retain the full effects of the developer.

"great service - accurate and timely"

"This stuff does what it says on the tin. It is also in a handy volume over some of the larger packages of similar developers. Having said this it will last for years in an open bottle according to the manufacturers. In my case this is not a worry as it get used pretty quickly. Not all modern films stain well, but the best ones are Panf, FP4, HP, Tmax 100/400, Acros 100, Bergger Pancro 400. You can generally get a deep green stain and it really makes wet darkroom printing easy, but depending on how you expose Grade 3 might become a normal start. Take time to get the Bergger recommended exposure and development times, the well known web site is quite a way out on starting development times. For those that use 4x5 or larger sheet film exposing the negative becomes more artful and controllable to get that perfect neg. You will see once you get the timing right better graduation in the highlights and separation in the blacks making the perfect for early morning or late evening light. Make sure the safety instructions are followed this stuff will shorten your life expectancy if you start dipping your fingers into it!!"
