  1. It's ok to break up a 4 gallon kit and use it in 1 gallon batches, but as a previous poster pointed out, exposure to air will ruin 777 quickly. Even though I keep mine tightly capped in full bottles, I change my working gallon of 777 once every six months. I mix up a fresh gallon, replace half of my working gallon and use the rest as replenisher.

     

    777 was designed to be heavily used in 4 gallon deep tanks. You need a lot of solution to use it well. I never develop more than two 8x10 sheets (or rollfilm equivalent) per gallon of solution.

     

    Hope this helps.

  2. For a normal 400TMax negative to be contact printed on Azo, try 9 minutes at 70 degrees F using the 1:100 dilution. This is essentially the same time I would give this film in ABC pyro. I don't use the other two films you mention, so can't help you there.

     

    Jay DeFehr can probably tell you a lot more. I haven't enlarged any of the negatives I've developed in this excellent concoction.

  3. One of the things Steve Sherman advises with semi-stand development is to never exceed dilutions of 1:200. I did, once, and the results were disastrous. You may get tremendous contrast, but you will lose the all important local contrast in the midtones, and this is to me the real advantage to semi-stand development in the first place.

     

    Attached is an unmanipulated scan of a print I made on grade 2 Azo (the last run done in Canada - the mushy stuff) of a 400TMax negative developed in 510 pyro using the semi-stand technique. 1:200. I put the darkest part of the picture on Zone IV and there was a whopping 1 zone of tonal range. The brightest part of the picture fell on Zone V. The negative has so much contrast that I had to make custom burn cards from proofs to burn in certain sections which were too hot. (On Canadian Azo!)

     

    510 Pyro is remarkable developer.

  4. Although I don't use pyro developers often, I do use 510 pyro for the occasional semi-stand or minimal agitation negative. It is the best of the pyrogallol and pyrocatechin based developers that I have used. It gives me a nice green image stain on 400TMax, which I don't get with ABC. It yields much less fog stain than I get with either Pyrocat HD or PMK.

     

    I'm not sure that agree with Jay about the full speed. I still rate all my TMax at 200. However, when I need a pyro developer to expand a really flat scene, 510 just can't be beaten. I showed one of my 510 semi-stand negs to Steve Sherman and he said that it was as perfectly exposed and developed as any he'd ever seen. After receiving such high praise, how could I use anything else?

  5. Do you know any photographers whose prints you admire? Look at their negatives. The negative is a step along the way to producing a print. It must contain the information which will enable you to produce the print you want. The negatives I make to be used to make contact prints are, in general, far too dense to be used in an enlarger.

     

    Once you learn what a good negative should look like for your particular photography, you then need to learn how at a glance to tell if a negative is underexposed, overexposed, underdeveloped or overdeveloped or any combination of improper exposure or development.

     

    The only way to tell if your negatives are any good is to determine what kind of prints they produce.

  6. Jay:

     

    I think the single most telling attribute would have to be reciprocity failure. Try racking your lens down to f/90 or so and making a 1 minute exposure. Give it a tabular grain reciprocity correction of 1.5 stops and then see if the negative is either close to correct or still 4 or 5 stops underexposed when developed. That should tell you for sure.

  7. For uniquely beautiful skin tones, I find the Efke orthopanchromatic films unsurpassed. The 25 and the 50 speed. I rate them at half the recommended speeds. Since you're shooting with a 35mm camera, you'll want the remarkable sharpness and fine grain these films deliver. Try them. I can't imagine that you'd be disappointed. Behind a Leitz lens they should produce absolutely magnificent pictures.
