  1. QUESTION ASKED ABOVE: By the way, how do you carry two cameras at the same time (if any

    of you do)? I do not enjoy weighing myself down with a heavy or cumbersome kitbag.

     

    REPLY: Take the lens off one of them and put that one in your pocket. If you need two lenses,

    buy a lens holder that fits underneath the (other) camera.

     

    BTW, for me it is 2x M7

  2. For nice grain I would recommend Rodinal developer diluted 1+25. Any film will do. TMX

    less than other.

     

    TMZ gives a grainy impression with every developer, some more, some less.

     

    You may wish to try TMX developer. If you read the instructions carefully you will see that

    some development time suggestions (Yes, that's what they are) are shown in bold. There

    is a reason for this.

     

    Have fun.

  3. Last year I had a lot of exposed film when going thru CDG and I asked for a hand check.

    No problem, they said, but it will take some time. I had plenty of time so I said OK. They

    swiped each individual canister and checked the swiped cloth in some sort of analyser.

    There is no way in the world they could offer this service except on an exceptional basis.

    The staff was polite and corteous.

     

    Still CDG can be a nightmare, there are just too many passengers, and it is too big.

     

    Since a couple of years, there is a new law in France giving people more right to their own

    picture and pictures of their property. If the letter of the law is followed, then you can't

    photograph anybody anywhere. My experience after having spent six weeks in Paris

    recently is that people are very cooperative and don't mind if you include them in their

    picture. I am sure there are situations when they would object to having their picture taken

    by a stranger. In that case I would not describe them as "nazis"

  4. If in doubt test your fixer. A good way to do this is to put the (35mm) film leader in new

    diluted fixer and note the time it takes for it to clear. Do the same test with old diluted fixer

    and see how long it takes. If it takes more than twice the time it took with new diluted fixer,

    then you better not use the fixer. Safe fixing time is twice the clearing time.

     

    That fixer is cheap is no reason to dump perfectly good fixer. Water is quite cheap where I

    live, but I still save rain water and use it for the garden rather than use drinking water.

  5. The minimum amount required is the amount that will prevent drops forming on the film

    once you have tapped the reels to knock off water before hanging the film to dry.

     

    We are talking about very small amounts of wetting agent. I use a small bottle used for eye

    drops for measuring. Pharmacies sell these bottles for lesss than one dollar. Buy the

    smallest size, the little glass tube then holds one milliliter.

     

    I use Mirasol as wetting agent. The recommended strength is 1+100 to 1+200. I have

    found that one third milliliter per film in a Paterson tank is sufficient. Paterson tank use

    300 ml per film, so my strength is approx 1+1000

     

    Use 1+1000 as a starting point for your test - and you will be amazed by how little you

    need.

     

    And, of course, use demineralized water for the last bath.

  6. Gee guys, I wish I had such top rate equipment and such steady hands and two such good

    eyes that I could measure Rodinal in a way that would enable me to notice the difference

    between 10 ml and 10.2 ml.

     

    The negative densities will be more affected by other factors than those 2% more or less

    Rodinal.

     

    Now let us all go out and take pictures.

     

    And stop worrying.

  7. that a-tech-pan must be a truly sensational film!

     

    i clicked on the link above and scolled down to the table.

    which gives the following density values for zone III

     

    exposure index 25 = density .14

     

    exposure index 32 = density .26

     

    exposure index 50 = density .41

     

    a truly amazing film.

    a must-buy

     

    well, perhaps not

  8. Larry:

     

    that is interesting. What size negative is it? What EI did you use and how did you develop

    in Diafine?

     

    I tried Rodinal with Imagelink using the same dilution and time that gave me good results

    with Tech Pan shot at EI 25, but it did not work with Imagelink. Same story with Xtol. I

    estimate the EI needed would be around 3 and that is not practical at all ;-(

     

    I got good results with FX-39 and TechPan. Have you tried FX-39 with Imagespeed? I

    haven't

    My should people hate Erwin?

    He has no influence on their life.

    If they do not like him, they can just ignore him.

     

    Have a good day!

  10. Kodak's published development times are way too short, as has been mentioned here

    frequently.

     

    In addition to what is said above you need a digital stop watch for 10 dollars.

     

    Then check how long your thermometer takes to indicate the correct temperature when it

    has been laying around on a cold desk at 17 degrees C and the developer temperature is

    20 degrees C. If it takes more than 20 or 30 secs, then get one that reacts faster.

     

    Then take a series of shots of a greyish surface. One shot at "correct" exposure and four

    more shots; each underexposed one stop more than the previous starting with a one stop

    underexposure compared to the "correct" exposure. And four shots each overexposed in

    the same way.

     

    If the thinnest negative is as thin as the film base (between the sprocket holes if you use

    35mm film), then the film speed setting was too high. If the densest negative is so dense

    that you can see nothing through it, then you developed too long. (Obviously not your

    case!) For a detailed analysis you need a densiometer.

     

    And stay with TMX

  11. Not many comments to your question "Does either the Summilux or Summicron versions

    of the 35mm and 50mm lenses obstruct the viewfinder in any way?"

     

    The reason for the non-comment is that in real life this is not an issue, but the answer is

    YES.

     

    I can only speak for Crons, and only for the latest versions. With lenses set to close

    distance more is obstructed than when set at medium distance or infinity. For the 35 mm

    the square lens hood obstructs more than the round "vented" one.

     

    35 mm lens set to 10ft/3m does not obstuct at all with the lens hood off.

    50 mm lens set to 10ft/3m does not obstuct at all with the lens hood pulled out i.e. "on".

  12. That will depend on what film and what developer you use. Some are more responsive to

    an increase in development time than other. As an example, TMY is more sensitive to time

    change than Tri-X.

     

    In no case would I increase the time by more than 20% unless the first film developed was

    awfully thin

     

    Anyway, if you have increased exposure time by one half stop steps you are a bit too exact

    until you have an approximately correct development time.

     

    I assume you have got a good densiometer. Otherwise the effort will not be fruitful.

     

    Have you got a good (digital) thermometer? Do you know how long it takes for the

    thermometer to settle in and show the real temperature? Otherwise......

     

    Was you living room wall evenly lit?

     

    Etc

     

    And good luck

  13. QUOTE Forced to use Tmax developer I'd switch from TriX to Tmax 400...specifically because

    Massive Development Chart shows more sensible development times (6 minutes is too short

    for a beginner, makes fill and drain time as well as agitation too critical) END

     

    Or you can continue using Tmax developer and dilute more to get longer times. (You will

    need higher delevoper temperature, like 24C, for higly diluted Tmax, I think I remember.

     

    Chris

  14. if your rental darkroom has a densiometer, then make a series of exposures of a grey

    evenly lit surface. no pattern on the surface, but it need not be a "grey card". start with an

    underexposure of five stops and then move upward in steps of one stop ending with a five

    overexposure. ask the lab to measure the densities and compare them to the standard

    values.

     

    you can then see if the film speed setting was ok and if the development time was too

    short or too long. somebody at the lab can, i am sure, do the density measurements and

    the vs standard comprison for you in five minutes.

     

    then you have solid facts to go by.
