Took me back about forty years when I needed some advice and there was really very little outside of the photo magazines. Books are obsolete before they are published and magazines are behind the times when they hit the stand. Now we have the "net" and can swap ideas instantly. I am beginning to understand the value of the "net" more each day. Just wish I could have foreseen the E-Bay runup! Well, enough of that nonsense, let's get to the business at hand of providing some of my experience which may have very little value in your search for photo technical excellence. TRULY FINE GRAIN HIGH ACCEPTANCE FILM AND DEVELOPING FILM It is my opinion there is really only one film on the market that will do justice to the Lecia lenses and that is the microfilm based film marketed by Kodak under the name Tech Pan and is available through most stores and if not on the shelf in your area just call B&H for a supply. Best to order in bulk and load your own cassettes because it is expensive when ordered already loaded but you might get a few rolls for testing. This film may be shot at E. I. 100 but I really recommend E. I. 32 for the way I shoot. Then develop in Kalt Brandeis developer TEC or the Willi Beutler developer that was the base developer for several developers no longer on the market. Beutler was a chemist/photographer was posed the question "why wish for sharp lenses and films and then use developers that dissolve the silver grains thus degrading the image? His response was that it was foolish to dissolve the silver grains. Use a developer that reduced grain clumping to a minimum but that did enhance edge accutance and keep the wet time to a reasonable minimum. The first commercial developer based on his formula was Tetanal's Neofin Blue but it took about 14 minutes when properly diluted to develop a roll of KB-14 and then rinse, fix, rinse and antistatic added another 10 minutes. Then Mike Tatem and a chemist at Plymouth Products in Chicago hit on the TEC formula that is another derivative of the Beutler formula, just more concentrated so development time is less, and that developer achieved instant fame among those who were looking for a developer that had all of the benefits of Neofin Blue but a wet time that was much more reasonable. E. Leitz New York began to use nothing but Panatomic-X and the TEC developer in their training classes and pressed the short wet time on anyone who would listen. Was really a great combination! Pan-X is now gone but TEC PAN is even more fine grained may be exposed at about the same exposure index. I even had Agfa run a special lot of microfilm to see if the current Agfa microfilm was the same as the film the H&R was selling in the 70's and early 80's and it does not seem to be as good for general purpose work s the older stock. Therefore, I recommend TEC PAN. I even use it in the Hasselblad and find that it is difficult to distinguish Hasselblad 16X20 prints from Leica 16X20 prints. Not sure how the comparison will be with the new variety of Leica lenses but the 100 mm APO on my R-8 gives the Hasselblad prints a run for their money. DEVELOPERS I have been a Leica user since 1957 with most of my work being done in b&w. At that time Panatomic-X was the finest grain film available and I used it until it was discontinued. It could be used an at exposure index of 100, processed in at least three or four good developers such as F&R X-22 (no longer on the market), Rodinal (seems to cause grain to clump thus causing an apparent increase in size of grain), in my opinion the best was the Plymouth Products developer named TEC for Thin Emulsion Compensating (a derivative of the Willi Beutler developer) which is STILL AVAILABLE, and the Willi Beutler formula that you can mix yourself with no more than three (3) chemicals (metol and sodium sulfite are mixed separately and stored in a brown bottle and the sodium carbonate, the activator, is mixed and stored in a separate bottle, all of which is done for longer shelf life but I would recommend it not be kept for more that three (3) months before dumping it. TEC instructions recommend three (3) inversions every 30 seconds but I recommend no more than 3 inversions every 60 seconds. This adds about 2 1/2 minutes to the development time but that isn't bad. Development is normally around 8 minutes, a 30-45 second rinse, one minute in Ilford fixer (do not add hardener to the fixer because it will make it very difficult to remove the fixer in the rinse stage and do not use a fixer eliminator as it seems to swell the emulsion to allow the fixer to escape thus causing grain clumping), then about 30 seconds in an antistatic bath. Hang to dry in a place that is as dust free as possible. I use the Ilford three (3) bath method of washing out the fixer. Put a gallon of filtered water in a large juice container, cool or warm it to the same temperature as developer, rinse, and fixer temperature, then fill up the developing tank with the wash water and move the reel or reels of film up and down five (5) times, pour out the contaminated wash water, refill the developing tank and move the reel up and down ten (10) times and dump, then refill and repeat but for fifteen (15) up and downs with the reel. Dump the wash water and move the film into the antistatic bath for about 30 seconds. Hang to dry. When thoroughly dry (normally the next day), but into strips and file in the clear negative protectors on the market. You will have to experiment to get the best exposure index and development procedure for you own work. This should get you started. Be consistent so you may change one thing at a time to see what is the new result. I still have a difficult time changing just one thing at a time because I am impatient like everyone else. TANKS It is my opinion the old Nikor type stainless steel tanks that allow the inversion method of agitation is best for the very, very slow films such as TECH PAN that are very contrasty to begin. I would try to find a used Nikor tank (no longer made) that is the two (2) reel size. Do not pour the developer in and out through the opening in the lid. Takes too long and the film make not have even development. Fill the tank with developer, then ease the two reels into the tank, place the top on the tank and invert about ten (10) times, bump the tank on the bottom of the water jacket to dislodge air bubbles on the film. Put down the tank in the water jacket, and let it rest for 60 seconds, then invert twice and put down. Do this for the time selected. I suggest eight minutes to begin. Remove top of tank, lift reels out of developer, put them in a container of filtered water and move up and down for 30-40 seconds to remove most of the developer and reduce chance for emulsion damage when the chemicals in the fixer hit the sodium carbonate from the developer. At the end of the rinse, lift out the reels and place them in the fixer (do not use hardener), and move the reels up and down for about one minute. Drain the fixer and move the reels into the first of three (3) washes. Get the three-bath wash info brochure from Ilford. Then drain wash water and dip reels into antistatic bath for 30 seconds. Be sure to put the stainless steel reels through the dishwasher to remove any traces of the antistatic bath so it does not react with and damage the developer the next time you process film. ENLARGER I had a V35 and it is a nice enlarger but, in my view, it was designed for color work and is too "soft" for b&w work. The negatives must be so over developed to get reasonable contrast they are degraded. My recommendation would be to keep the V35 because you will want it for color. Pickup one of the wonderful Focomat Ic enlargers or even a Valloy II. Install a 50 mm APO lens and it will knock your eyes out when you see what a Leica lens and TEC PAN developed in TEC will provide. It may take a few tries but you will be astounded. By the way, try to find one of the Focomat Ic enlargers because the "c" means there is a tray ABOVE the lens for contrast filters. DO NOT PUT THE CONTRAST FILTERS BELOW THE LENS. TRIPOD It is absolutely essential to use a good tripod. If using a reflex camera, trip the mirror first so it does not give the poor camera and super lenses a hard "slap" when it flips up. Of course, use cable release and don't jerk it. Squeeze slowly like you were squeezing off a shot at a target several hundred yards away. Come back with questions if I may clear up something stated above. Hope this gives you some food for thought this Christmas morning. Wouldn't it be great if those who are really good would join this conversation as my knowledge is really limited. DonjR43198@aol.com
