  1. Re: Many paper developers back-ordered or special order with long delivery lead

    Philip,

    Mixing you own print developers is not nearly as demanding as many make it seem. The initial expense for the raw chemicals is the up-front investment, but after that, you can mix what and...
  2. Re: question about stacking square filters

    When you stack colored filters, you just get the effect of the strongest filter. E.g., when you stack red and yellow, the yellow filter passes red orange and green; the red filter cuts out the...

    I've been using Bainbridge Alpharag Artcare board in a couple of colors of white for some years now. It's buffered and has impurity-absorbing particles (activated charcoal?) embedded in it, so not...

    Re: Dektol Issue

    Check your Dektol stock and see if there is anything floating around in it first. If so, the problem could be crud in the bottle (as Philip mentions) or it could be impurities in the Dektol itself....
  7. Re: Seeking Ideas For Replacing Film Holder Labels?

    Fingernail polish remover (acetone) and a cotton swab works for me most of the time. If the marks are pencil, try a white eraser first.

    If the ink is so stubborn that the acetone won't do the...

    Re: Fiber based paper thoughts

    I'd love access to a 500T or similar. I have absolutely not enough room to have something so big in my workroom. As it is, I have to wrestle the 210 in and out of the storage area and set it up for...
  9. Re: Nikkor 500mm Tele - any problems with tilt/swing?

    Rear movements are just the same with tele lenses and with "normal" ones. It's the front tilt and swing (not rise) that are trickier because the lens nodal point is actually out in front of the...

    Re: PMK and open sky blotchiness

    Ha,... The 160° was film speed/E.I., not developer temperature. The "°" was unnecessary and maybe misleading; likely confusing the DIN designation in degrees with the ISO-style.

    Anyway, to the...

    Re: Storage box for my Toyo 45D

    Nice,

    Kind of like the old cases for the Graphic View cameras. You may want to cover the holes with something for long-term storage to keep dust/bugs, etc. out though.

    Best,

    Re: How To Use Stouffer Step Tablet?

    Re: How To Use Stouffer Step Tablet?

    FWIW, my tests with different papers and developing times have all shown that extra development basically increases paper speed, but not contrast. I imagine different papers react differently.

    Re: Missing exposure equation

    Philip,

    The calculation you want is how to find "stops to open the aperture" from the exposure factor, which is log2 of the exposure factor.

    However, I don't know how to write the formula for...
  19. Re: How do you remove silver nitrate stains?

    As mentioned, you should use fixer to remove the now-invisible stain after bleaching or it will come back.

  20. Re: How do you remove silver nitrate stains?

    Assuming the stain is mostly metallic silver, you can rehalogenate and then use fixer to make it soluble in water.

    A solution of chlorine bleach should turn silver into silver chloride. After the...

    Re: Using Benzotriazole

    It would appear that your benzotriazole is coming out of solution. The "cotton wool" state is common for benzotriazole.

    Drew has answered your question well. Let me elaborate though, at the risk of complicating things.

  32. Re: Merering: Spot Metering, Reflective, Gray Card, Average

    Nope. Base your exposure on the shadow value. Averaging high and low readings can lead to underexposure when the subject brightness range is great. Overexposure if the SBR is small. You measure the...

    I read the shadow and place it where I want it; standard Zone System practice. This reading determines my exposure. Averaging high and low readings is simply bad technique and often...
