When you go into your darkroom year after year and print your negatives, you slowly become acutely aware of the most minute changes in image quality. It’s this intimate contact with your craft and subject that allows you to see the minute changes that the materials and process make. The prints you made in years past may now seem to be lacking. Even those negatives you were never quite able to interpret into a suitable finished image may somehow come alive when you apply new wisdom and technique. Everything in the chain of events, from the camera to the finished photograph can and will make a difference. Some can make a vast amount of difference; others can be very small. Yet they all add together in the finished print.
When we first started working with Pyro developers it took some time to realize exactly how the different look and feel of the film would translate into the finished print. There are those that say there is no difference between different film developers. They may also say there is no difference in the film you choose. That is like saying there is no difference between Ford and Chevy; no difference between red or white wine. Maybe for some this may be the case. But for those that take the time to really look and absorb the image, there is always a difference. Fred Picker said, “different is not the same!”
Never let the opinion of someone else dictate your choices; either in life or photographically. You need to prove all things for yourself. Never fall prey to hearsay. Test everything for yourself. If you feel the need to explore Pyro developers, by all means take the time to do your own testing. To really know, you have to find the answers for yourself. A quick dabble will not do. You need to establish your personal film speed and developing time. Then go out and make photographs in the real world. And not just a few photographs, but a lot; over time; test; adjust as needed. Give yourself at least a years worth of real photography. Then you will have enough experience to make a really personal and informed decision.
Is there a real difference in a Pyro film developer? This is a question you will have to answer for yourself. Just do not fall into the trap of depending on someone else to make the decision for you. Pyro was good enough for Edward Weston, Morley Baer and many others. If we could only ask them their opinion.
Over the past 20 or so years Pyro film developers have again become popular, with modern reformulations for modern film. John Wimberley, Gordon Hutchings, Sandy King, Jay DeFehr, among others, have done a lot of research and have formulated numerous reincarnations of Pyro film developers, specifically designed for use with modern film. Steve Sherman, Bob Herbst, Michael A. Smith and Steve Simmons have written extensively about Pyro developers and their unique qualities. Susan and I have made our choice based on our own real world experiences. We join with the many others that are also Pyro developer users.
