    Re: 45mxt and contrast filters

    You guys must have a different filter-holder than I do. I have a 45MCRX (with the tapered bellows) with an above-the-lens filter holder that takes 6x6cm filter (2 1/4-inch squares), no curved end. ...
  2. Re: Harman Direct Positive Paper Question

    Uh.... a positive print of a negative is... A negative! (i.e., no reversal of tones)

    Note that normal photo paper is actually a negative material: it reverses the tones on the negative to make a...

    Re: 45mxt and contrast filters

    If you've got the below-the-lens swing-away filter holder, they take square 2 1/4-inch filters. The corners just stick out and leave some room for handling.

    If you have the above-the-lens...

  6. Re: How to tell if metol (in powder form) has gone bad

    If the Metol powder is only light brown, it should work fine. Of course, the test would be to mix some D-23 and develop a small piece of film (leader or the like) in daylight to see if the developer...

    Re: Incident Metering Question

    I'm not that familiar with BTZS, but the principle, when you meter the shadow area, is to give less exposure that the meter reads since you're judging light falling on the shaded areas of the scene. ...

    Spot meter and base your exposure on a shadow value just like you do for 4x5. Especially since you already have a spot meter and know how to use it. Film size has no affect on metering technique.

  11. Re: Tape for replacing film holder hinge flaps?

    Bookbinding tape is great; it's flexible and permanent. Really, any tape that is thin, flexible and won't break or degrade with time will do the job.

  12. Re: Negative negatives - using SP445 Tank

    Have you considered that the problem may not be with your developing method or the SP-445?

    Which film are you using? How old is it? How has it been stored? The film itself could be the culprit.

  24. Re: My Omega Condensers have scratches - any negatives (hah) with using a diffuser?

    I guess I stand corrected about using something opaque to black out the scratches. Since the scratch can come into focus, so can the black mark.

    Here's hoping your new condenser set does the job....
  25. Re: My Omega Condensers have scratches - any negatives (hah) with using a diffuser?

    There's your answer; Bob beat me to it. It is standard practice with lens defects just to black them out. The same should apply to condenser lenses. However, I could be wrong... you may see the...

    I imagine that what you are seeing is the silver-solvent effect from the D-23 developer used 1:1. At that dilution, the amount of sodium sulfite (about 100g/l if I recall) acts as a...

    Louis makes a good point: be sure to check for leaks with a filmholder in the camera. Check at all orientations of the back too.
