PYRO DEVELOPERS; SUBTLE YET DIFFERENT

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.

Pyro Do Your TestingOver 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.

IS A PYRO FILM DEVELOPER RIGHT FOR YOU?

Pyro Staining Developers

The first time I used pyrogallol was unforgettable. During lunchtime on a hot summer day in 1970, I left work and climbed a hill nearby to expose some test negatives. That evening, I tray processed the 4×5 Plus-X in Kodak D-1, a classic version of “ABC Pyro.” When I turned on the light, what I saw made my heart pound. The negatives were beautiful: tones were spectacularly differentiated throughout the density range, especially in the highlights. And what sharpness! I knew I’d finally found my developer.*
-John Wimberly-

I believe that an artist is never satisfied. As photographers, we all started somewhere. For me it began many years ago; more than I care to count. I can remember when it was a thrill, almost magic, to just get something from the camera to a finished print. My early attempts now do not excite me that much but they were where I started and I cannot deny my vision and skills have changed over the years. My wife and I have continued to hone our photographic vision and skills and we continue to evolve. The journey through creativity is never ending.

So, what does this all have to do with developers? Film, camera, lenses, chemicals and process are all only a means to the end product; the finished print. Each item alone may or may not be of major significance, but everything plays a roll all the way to the end. For many years we used Kodak HC-110 film developer. I fine tuned the developing times and even had my own dilution that I called Dilution JBH. We have hundreds of LF and ULF negatives processed in HC-110. This is about the best film developer you can use if you are just starting out. I am not a practitioner of the film of the month club nor the developer of the month club either. I believe you choose carefully, then spend your time wringing everything you possibly can from your choices. But, as I say, an artist is never satisfied. There is always that little something more.

This drive for continually progressing forward is what led me to begin exploring Pyro developers. I did a lot of research. We both did a lot of real-world testing, using numerous Pyro film formulas. This quest turned into several years of experimentation, but we both feel we learned a lot and did find that little something extra. We both agree the effort was well worth the time we invested.

Pyro film developers are different. Though the difference is very subtle and really cannot be fully appreciated unless you have some experience with the more traditional developers. I would never recommend that a newcomer to film photography start with a Pyro developer. You need to refine your skills first with a non-staining developer, so you will see the minute differences a Pyro developer creates.

PYRO STAINING FILM DEVELOPER

PyroCat HDI had written about my experiments with Pyro Staining Developers back in October of 2010, and that should make it very clear that I have chosen my favorite film developer.  Take a look at my previous post, “THE PYRO-CAT IS OUT OF THE BAG.”  Of all of the Pyro Staining Developers I tested, PyroCat-HD by Sandy King has proven to be, hands down, the best of the best.   If you are seriously looking for the finest all-around film developer, I would strongly suggest you take a serious look into PyroCat-HD.

Sandy King has done his research and formulated an excellent developer.  Also, he has a new web site that is outstanding.  I was pleased to find that he has a section dedicated to his technical writings which contains his original article on Pyro Developers.  If you are seriously thinking about working with Pyro Developers, I would highly recommend you take a look at the article,  “AN INTRODUCTION TO PYRO STAINING DEVELOPERS, WITH SPECIAL ATTENTION TO THE PYROCAT-HD FORMULA” by Sandy King.

There is no need for me to go into the details of my experiments with Pyro Developers since I have covered what I learned in my previous BLOG post.  I would also recommend the above mentioned article by Sandy King, which covers a lot of what you need to know about Staining Developers.  All I can add is that  PyroCat-HD is the only developer we now use.  Maybe you should try it yourself?

WHAT PAPER DEVELOPER ARE YOU USING THESE DAYS?

AmidolSo. . . everyone has their preferred brands, methods, techniques and such. I have mine for sure. As Fred Picker said, “if you have been around for twenty years or more and haven’t formed any opinions, what have you been doing?” I miss Fred!

There seems to be a lot of paper developer formulas floating around. My wife and I have tried our share of so-called ‘magic’ formulas. We have been down the Amidol road, and don’t get me wrong, Amidol is a great developer but it is far from magic. Amidol is about the best I have found for Azo. Yes we do print on Azo, in fact, we have a stock of it on hand. I would just like to go on the record as not being a person that subscribes to the idea there are magic bullet formulas. There is what works for you and that can be anything that suits your way of seeing. Anyone that has a one-size-fits-all attitude, usually has something to sell.

We have had our frustrations with Amidol developers. And I am not convinced that it is the best, certainly not the only, developer suitable for Azo or any other paper. In a side-by-side test my wife and I determined that Amidol was our developer of choice several years ago. There is a subtle edge there that is not something you can put into words, but there is a difference we decided worth exploring. But Amidol is expensive and can be frustrating to use at times. Yes, we have tried all of the popular formulas. I have just not been too impressed with the results I have obtained at times. What I was searching for was a cold-tone developer. Not only for Azo, but for the other printing papers we use. At times Amidol was still giving a green cast on Azo. Not bad but annoying and required lengthy toning in selenium to offset. I like a cold, neutral tone for most of what I print and the Amidol formulas just wasn’t consistent enough for me. I was not happy with how things were working. It was time to do some research.

I found a lot of interest on the Internet about a Pyro base paper developer formulated by Donald Miller. Mr. Miller named his developer Pyro Plus Paper Developer (PPPD) and after reading about this formulation I was inspired to give it a try. Believe me it takes some inspiration to get me to try something new, but I was frustrated with Amidol and I needed some good news for a change.

From all of the discussions about PPPD I found one thing was clear; there were numerous variations to the formula. The original published formula called for both Pyrogallol and Pyrocatechol. Now this is where things get a little confusing. I don’t recall where I found the particular variation that I tried, but there was a suggestion from somewhere to replace the Pyrogallol with Citric Acid. Not sure where I found that, but that was the formulation that I first tried.PPPD-JBH

From what I gathered, adding the Pyrogallol and changing the amount of Potassium Bromide makes a more warm-tone developer. I was not interested in warmer, I wanted a cold, neutral developer. To my surprise the variation I tried worked very well. It more than met my requirements, and so far, has yielded very neutral cold tone results on the Azo we have on hand. No more green tint, just what I wanted! It has also proven to be excellent with all other papers we use. And, for those that are economy minded, Pyrocatechol is much cheaper than Amidol.

PPPD keeps very well in an open tray once mixed, but should be dumped at the end of a printing session. I have never had it to die in the tray from oxidation. It does die from exhaustion, just like most any other developer. I would estimate that after about twenty 8×10 prints per liter, you should start looking to mix some fresh developer.

This particular formula also keeps well as a premixed two-part stock solution. Part ‘A’ is mixed 1:1 with part ‘B’ for use. I found that by mixing one liter of both part ‘A’ and part ‘B’ and storing it in full brown glass bottles it keeps at least six months. At least at this point in my experiments that is as long as I have stored the stock solutions. I keep three to four one liter bottles mixed and on the shelf in the darkroom. When we go to print, you just dump a bottle of part ‘A’ and part ‘B’ into a tray and away you go.

I really like this developer and my wife is using it also. So if I am asked what developer I am using, I say now days it is my variation of Donald Miller’s PPPD. My bottles are marked PPPD-JBH for my personal favorite formula.

Oh. . . almost forgot. . . I guess if you have read this far you are interested in the version of PPPD we are using.  Here is the formula that we have found to work very well with every paper we use, including Azo. Maybe it will work for you. . . maybe not. The only way to find out is to, as Fred Picker would say, “TRY IT!”

PPPD-JBH Formula

Please note that this developer contains chemicals that could be hazardous. Practice safe handling procedures when mixing chemicals. Wear gloves or use tongs when working with PPPD. In fact, it is a good idea to wear gloves when using any print or film developer.

Keep in mind this is a cold-tone developer. If you search the Internet you will find more information on other variations of the PPPD formula. Supposedly adding Pyrogallol and varying the amount of Potassium Bromide makes this a warm-tone developer, but I have not tried it, since I was not interested in warmer print tone.

I would like to personally thank Donald Miller, and all the others involved for laying the groundwork and publishing this formula, and its numerous variations, for Pyro Plus Paper Developer. Anyone wishing to experiment with PPPD, or seeking more information, try an Internet search for Pyro Plus Paper Developer.

Here you will find the original Pyro Plus Paper Developer formulated by Donald Miller;
