  1. Re: Adding a 4x5 back to a 8x10 body......is it worth it

    One reason for the 4x5 back is that it is a good way to extend the reach of your lenses. If you have a framing that requires a very long lens, longer than anything your camera can accommodate, a...
  2. Re: How do you process Fiber base or Barite double weight enlarging paper ?

    Yes, the rate of fixer exhaustion is directly proportional to the amount of fixing done (i.e., the amount of high values in the print). I advocate using something like Hypo Check to check the state...
  3. Re: How do you process Fiber base or Barite double weight enlarging paper ?

    Just to clarify about the extended life in a 2 bath system. The initial results of fixing are early byproducts that are highly adsorbed into the fibers of the paper and as a result they do not wash...

    Re: 8x10 DOF examples

    It is a myth that 8x10 suffers from problematic DOF. Yes, the DOF is smaller because of the longer equivalent focal lengths for the format. This means you stop down more for the same DOF. People...

    Re: Agitation Question

    I also wanted to add (as pointed out by Steve and Doremus) that any curve shape due to agitation requires careful massaging - it will only work if you restrain highlights while allowing shadows to...

    Re: Agitation Question

    I like my negative to be developed as close to a straight line as I can. It is rare for me to deal with photographs where the highlights are small and fall out of the scale of the paper. Usually, if...

    Re: same old tripod thread

    In smaller formats, the tripod is arguably the main source of weight. In LF, the weight of camera, lenses, holder is already pretty large and the tripod is just one more heavy thing to carry. LF also...

    Re: 8x20 light leaks?

    Some additional things to keep an eye on.

    1) A pinhole at the lensboard can act - well, like a pinhole. Short exposures can sometimes result in what looks like movement or a double image - long...

    Re: Schneider 360/620 convertible

    The nodal point of the converted lens lies well out in front of the actual element, so you will require a good deal more than the 620 mm to achieve infinity focus, more for focusing closer.
