  1. Don't know of any chemical suppliers in Australia but if you don't

    find any give Artcraft Chemicals a call in Schenectady N.Y. USA.

    (www.nfinity.com/~mdmuir/artcraft/html) Pretty sure he will do

    international shipments if laws permit. Has very good prices as well.

  2. Sorry, I have to correct myself. Development will affect your shadows

    but they are generally fully developed in the first few minutes so use

    development time to control your highlights.

  3. I would say underdevelop (n-1 or n-2) and you will probably get a

    decent neg. Your highlights are going to be what the development will

    affect. Development really won't do anything to your shadows but

    you'll probably have really nice detail in them and they can always be

    printed down. Good luck!

  4. I almost exclusively shoot with my Kodak 135 WF Ektar. It's an

    extremely sharp lens and I routinely shoot at f/32. Diffraction

    causes lots of problems in B&W as well as color but I have not noticed

    any problems. The 100mm & 135mm only stop down to f/32. The WF's are

    wonderfully light and sharp but you have to hunt for one in mint

    condition.

  5. I was baffled by a situation today in which my subject was a vertical close-up of a dense bank of reeds. The bank of reeds began about a foot from the lens and extended away from the lens to about 15 feet. My intention was to create a strong, powerful feeling yet was unable to do this because of inadequate DOF. No matter what aperture or movements I used I could not retain sharpness front to back. I've never encountered a DOF problem as severe as this. My question is what could I have done to correct this? (I was using a 4x5 monorail with all movements available and a 135mm WF Ektar. I would have liked to use a longer lens but I neglected to bring my other lenses with me)
  6. Question #1 I use 4x5 frequently and have never had a problem with

    uneven development using trays and tubes. If anything you'll have

    more of a problem with tank developing(uses horrendous amounts of

    chemistry,they leak, and you have no control over individual negs).

    A JOBO would be nice but they are expensive and if you are looking to

    cut costs that's not the way to go. Trays and tubes offer the most

    control. Question #2 You're gonna be hard pressed to keep any

    equipment above 35mm under 6 pounds! (this assumes you carry more than

    just the camera body) The Arca Swiss might be a good choice

    considering just weight and bulkiness and if you carry a couple film

    holders, lightmeter, 1 lens, loupe, and a decent tripod with head you

    might just make it under 20 pounds. When I first started using 4x5 and

    hiked more than a couple hundred yards from my car I thought maybe I

    made a mistake and should have gone with medium format. Once I saw my

    first couple LF negs. I didn't regret my decision. (they actually

    weren't that great but seeing LF negs. for the first time is really

    something) Question #3 Schneider and Rodenstock are really on par

    with each other. You might try some older classic lenses. Some are

    really nice and much less expensive than new lenses.

  7. I've also had a brief experience with Camera Care myself. I too saw

    their ad in Shutterbug and at the time was in the market for a 4x5

    enlarger for my current darkroom. Since I live about an hour from

    philly I decided to go check them out. Upon arriving I got the same

    impression as Josh and was not too impressed with their shop or their

    LF gear or how it was being kept. I did luck out though and found a

    Bessler 45 MXT complete (and in excellent shape exept for the

    thick layer of dust) with lens turret and it's price was quite

    attractive. I didn't expect to be buying an enlarger when I was there

    so of course the enlarger was too big to fit in my car. So, I asked

    the man if he could ship it and I was prepared to pay the shipping

    costs. I fully expected him to be able to ship it considering almost

    all mail order companies will ship the merchandise they carry. Well,

    this was not the case and he told me that I have to take it with me if

    I want it. Anyway, before my response gets too long, the enlarger is

    now in my darkroom after a hell of a lot of stress. My opinion of

    Camera Care is not negative but I probably wouldn't shop there again.

  8. Correct agitation is fairly critical when using PMK or any other pyro

    developer. The main reason is not necessarily uneven development but

    pyro has a strong tendency to cause streaking which will ruin your

    neg. During development a very thin layer of the developer will

    exhaust itself rapidly on the surface of the film. When there is no

    agitation (the agitation should be very vigorous) this layer of

    exhausted developer will begin to slide across the surface of the film

    causing the stains(streaks). Gordon Hutchings describes in detail the

    why's and how's of PMK and agitation in "The Book of Pyro." I have

    used an agitaion cycle of 10 sec. every 30 sec. which is longer than

    recommended with apparent success. Temperature and capacity are also

    really critical with pyro. Before I knew PMK was a one-shot

    developer, I ran three 4x5 negs. one at a time through the tray of

    PMK. When I was finished and turned on the lights I found the first

    neg. was beautiful but the other two were blank. 1 liter of PMK

    was fully oxidixed after just one neg.! (It has a larger

    capacity than this but the exposure to air oxidized it quite

    rapidly)Finicky stuff but can produce wonderful results.

  9. I just recently started desilvering my fixer using a 2 1/2 gal plastic bucket and and plain steel wool pads. I pour my spent fixer in the bucket then throw a steel wool pad in the bucket and put a lid on it.

    After about a half-gallon or so, I decant the liquid on the top and leave the sludge on the bottom to dry out. After it drys I put it in the trash. Is this an adequate method for desilvering fixer?

  10. I personally use graded papers too and so far Ilford's Ilfospeed RC

    works just fine for proofs and standard enlargements. As far as

    high-quality FB paper I think you will find a very wide selection at

    Freestyle Photo. (www.freestylesalesco.com) For a truly wide selection

    mail-order is the way to go! I just received my catalog today and was

    very impressed with what they carry. (prices are very reasonable) As

    far as I know they are the only company that carries Oriental papers.

    Though I have never used it myself, Oriental G is supposed to be a

    wonderful FB graded cold-tone paper. Ilford Galerie is another

    oustanding paper and even Luminos Classic. (though it doesn't tone too

    well in selenium) Oh, and Cachet papers are supposed to be very nice

    too! There is an enourmous amount of papers out there and most of them

    are top quality so it really just comes down to a matter of personal

    taste.

  11. I was leafing through Gene Nocon's "Photographic Printing" one day and came across a section on lith printing. The images produced in this process are beautiful. I noticed that all the major mail-order companies only carry Sterling Lith DW and Kodak is the only maker it seems of lith developer. My question is twofold then: First, does anyone out there have experience with lith printing and could they tell me a little about it? Second, is Sterling the only maker of lith paper?
  12. I've just started platinum/palladium printing myself. It is true that

    you don't need a darkroom but having one sure helps. There is some

    great text about platinum/palladium printing out there. One that I am

    using and find to be a very straightfoward introduction is Dick

    Arentz's "An Outline for Platinum and Palladium Printing."

    (probably not available from your library) This text is available from

    a number of photographic sources such as Photographers Formulary,

    Artcraft Chemicals and Bostick & Sullivan. (They all have web pages

    but can't remember their URL's) These places are great sources for

    chemicals, texts and some equipment.

  13. I have found the Toyo loupe to be satisfactory even more so when

    considering the price. Compared to the Schneider loupes, the Toyo is

    a steal. The optics are decent but I would have to say the

    magnification is a little low. Then again with the 6x, 10x loupes,

    one might have problems with actually magnifying the the etched side

    of the glass to the point of interfering with focusing the image.

    Besides, anything above 6x is overkill unless you absolutely need

    microscopic sharpness.

  14. I've recently begun deveolping my large format negs. in PMK Pyro. So far I've had good results. Disposal is quickly becoming a concern. I have been storing the spent solution in empty milk jugs but need to find a permanent disposal solution. I have a septic system and city water. Gordon Hutchings explains that for the past 14 years he has been draining the pyro from his darkroom into his septic system. I am concerned about taking this route because of pyro's toxicity. If anyone could offer a suggestion as to the disposal of it I would greatly appreciate it. Thanks!
  15. I remember reading somewhere that one can temporarily repair pinholes

    in a bellows with black photographic tape or electrical tape.

    Although this will probably work for the time being you might have to

    bite the bullet and buy a new bellows. They are pretty costly for an

    8X10. Maybe someone out there can offer a better suggestion>

  16. I recently purchased a Toyo 45CX. Though only having it a short while

    I can tell you the Toyo 45CX is a very sturdy camera (amazing for this

    price range!) The swing/tilt fuctions are a little stiff but this does

    not seem to cause a problem. One compromise is the back which I'm

    sure Toyo did to keep costs down. It's a standard reversible back but

    is very easy to get used to. As far as interchangeble parts go, I

    wouldn't base my decision to much on that because to do a format

    change especially from 4x5 to 8x10 is rediculously expensive.

    (somewhere in the neighborhood of $2500!!) I feel that the

    interchangeablity is a nice option to have though. I have no

    experience with a Cadet but all in all I feel the Toyo45CX is well

    made and can most likely withstand a ton of use.
