    Re: Focusing loup

    I switched to a free-hand magnifying loupe years ago and have never looked back. It happened by accident. I was in Venice photographing and had left my loupe and reading glasses at home. An...

    Michael has given you about all the advice that I would, but I'll chime in anyway, since he summoned me :)

  3. Re: Which first Rear Movement and Asymmetrical Tilt Chamonix 45F2

    As long as you're only using the lens stage rise/fall or lateral shift to reposition your lines so they correspond better with focus points, you're fine; you're not changing the position of the focus...
  4. Re: Large format copy negative from print

    Choose one of the recommended films (I'd likely go with TMX) and then make a few negatives of a print with a full range of tones. Rate the film 2/3-stop slower than box speed. Develop one for...

  7. Re: Which first Rear Movement and Asymmetrical Tilt Chamonix 45F2

    Asymmetrical tilts and swings are just modifications of axis movements designed to make the photographer's job easier when applying these movements. They may be a bit faster or more precise than...

    Re: Agitation and highlight density

    Changing agitation has the same effect as changing development time (or changing developer temperature). In just about everyone's view, it is better to keep temperature and agitation the...

    Re: Chemical age -- metol


    I'd be looking elsewhere for your problem and not at the Metol (I, too, have 30+-year-old bottles of Metol, hydroquinone and phenidone that all work just fine).

  10. Re: Which first Rear Movement and Asymmetrical Tilt Chamonix 45F2

    I think we're overcomplicating things for the OP. Let me take a stab at oversimplification :)

    Asymmetrical tilts and swings are simply axis tilts/swings with the axes displaced off-center. Using...

    The HT-2 test is simple. It's a lot easier and takes less time than reading "Mysteries of the Vortex," not that I'm saying you shouldn't.

    Re: 4x5 B&W development - no processor

    If you have access to total darkness for processing, my vote would be for tray processing.

    I've been tray processing 4x5 film for 35+ years. I find it the most flexible of all the options. You...

    Re: What photo paper grade means?

    If you end up using a fixed-grade paper like Lupex, then you end up with very little contrast adjustment possible at the printing stage. In the past, graded papers were made in several...
  16. Re: Push/Pull processing if Scanning Negative

    To clarify: I'm referring to black-and-white film and to the contrast gradient to which it has been developed, not the physical characteristics of the film itself. I know photographers who develop...
  17. Re: Push/Pull processing if Scanning Negative

    It does seem that film that has been optimized for scanning may not be ideal for traditional darkroom printing. A scan can get lots of information from a rather flat negative, but photo paper...
  18. Re: Beseler 45MXT with Zone VI cold head, info needed


    Unless things have been broken during storage, the cold-light head should work fine; there's nothing with the bulb that long-term storage should damage. However, if you need a new bulb, I...
  19. Re: Best 250 for architecture from a distance for a feild camera

    IM-HO, the last thing you need on a 4x5 camera is a huge 300mm f/5.6 Plasmat with more image circle than you could possibly use. They're in #3 shutters, require huge filters and weigh more than some...

    Beautiful images, McAir! Unlike Philip, I like the sharpness (sorry Philip...). Of course, small images on a computer screen aren't real prints, but these look great on my monitor.

    Re: Spoon measure needed, please

    According to the Darkroom Cookbook, 1 tsp. of Borax (sodium tetraborate) is 3.8 grams. Since the exact amount isn't that critical, you can just use that and go.

  24. Re: Anyone want to diagnose this negative?

    HC-110 reacts almost linearly when changing dilutions. So if you change from 1+31 (dil. B) to 1+63, you just need to double your original development time to get a very close starting point for the...
  25. Re: Moving to Spain. Can I send my negatives in the container?

    Pack them well-sealed in plastic bags along with some desiccant. As long as the container makes it to you and hasn't been flooded completely, the negatives should be alright.

  26. Re: Center filter question - usage on different formats

    You're right Alan, shifting (or raising/lowering) moves the optical center of the image on the film to an off-center position. However, if you can identify that point in the image, then you can do...
  27. Re: Center filter question - usage on different formats

    Vignetting is really the wrong term here. Fall-off is better.

    If you've got a center filter on your lens, shifting/raising/lowering the front or the back standards will make no real difference...
