  1. Hi Johnathan,

     

    As I understand it most people cross the 809 and 804 film themselfs,What I tested a few years ago actually 4/99 It was called Brown Tone. any thing over a 15 sec development time yeilded a mottle look to it. So I guess the powers to be decided against it.

  2. Greetings,

     

    I routinely use 8x10 Polaroids in the field. To process I bought a voltage inverter to run in the explorer. Which works well with no problems to the processor or the explorer. Keeping the film in the explorer after processing, I havn't noticed a dust problem.

  3. Bob,

    I bought a set of steel legs, and bolted an oak pallet on to them,

    added a sheet of 3/4" plywood cut to size, and screwed on painted all

    black. rock solid

  4. Hi Jacque,

    If that technique will not work, It is because some years ago, the

    developer formulation was changed to avoid the solarization, as it

    turned into a major problem for all T-55 users.

    I have printed from some 4x5 glass plates that belonged to a

    friends grandfather, I made a cardboard holder for the plate and used

    my enlarger, printed on standard multi grade paper. I have one RR

    5x7 glass plate was planning to do a contact print only with that one.

  6. Hi All,

    Are you aware, that in manufacturing that, The original suppliers

    of chemicals, no longer make the chemical needed for film, paper, and

    developer. also, chemicals produced today are purer that years ago,

    and are harder to work with. Machinery, wears out and the older

    technology that built it no longer exists, parts impossible to

    obtain. New machinery a lot built inhouse, as there is no on shelf

    inventory of what companys need for there unique product line. Every

    one that makes film, is going thru the same thing, we just do it

    differently from each other.

  7. Dave,

    While working on a test using T-55, walking up stream in a shallow

    river, I exposed 60 packets, went home ant found that all packets had

    blocked. Which is the sheet face sticking to the negative, due to the

    humidity of the evaporating water the temp was around 90 degs. Save

    the T-55 for use at a later date. I never gave it a thought as i work

    with this film daily. Oh Well.

  8. George,

    I use the processor in my explorer with a voltage converter, works

    fine, with no aparent damage to either.

    Rob, T-805, is what u would be looking for, Working with this for a

    year now, and still have major issues. Here's the hint, negatives

    develop in 20 seconds. Try clearing these in the field, tons of fun

  9. Morning all,

    Robert, Refrigerators are not ideal cold storage, as they are wet.

    UNOPENED Polaroid film, at a temp of 50 degs. 45% or lower humidity,

    will work best. Mt cellar at home is 60% RH. 50 degs. and kills color

    film in 3 days, what happens is that the envelope, is hydroscopic, by

    nature and absorbs as much moisture as it can, then this moisture

    bleeds in to the film.

    Polaroid Films are unique, because of the positive and negative are

    in contact face to face in the packets.

    The film should never be frozen as the chemicals in the pods will

    either separate upon warmup or they might burst in the freezer.
