  1. Re: Must your image be technical perfect ?

    Thinking more about this:

    Is a Rubinstein performance of Chopin without merit just because he makes a mistake along the way? Especially since the interpretation and the rest of the performance...
  2. Re: Must your image be technical perfect ?

    It's not an imperfection if it's intentional.
  3. Re: “Tripods for Bipods” (John Sexton new tech tip video)

    It was a bit monotonous for me. I had to play the video a 125% speed before it even sounded normal, and it was still soporific. I think they must have inadvertently slowed it down.
  4. Re: Grayish whites and other problems in my new darkroom

    The paper is light or age fogged. (I'm assuming here that you're printing well enough to get real whites when you want them, but if you're dealing with very thin negatives and are at max contrast,...

    Re: Negative Dark Patches

    Filmholder testing methods:

    Load your holders (with photo paper for economy) and leave them sitting out in the sunlight for a while. Flip them around making sure all the sides/edges get exposed...

    Re: Negative Dark Patches

    Borris,

    These are definitely light leaks. The most likely culprit is the spring back being pulled away from the camera body when you pull/insert the dark slide or the holder not seating correctly...

    Re: Will pull help me with this image

    The premise of your question is erroneous. Developing less (I hate the word "pulling" for N- developments...) will get you less tonal separation overall, including between bridge and sky.

    And, I...
  9. Re: Technique for increasing depth of field

    Bruce,

    Don't be too harsh... I think many of us assume that we want a particular framing, so when using a shorter focal length lens from a particular camera position, would end up cropping the...
  10. Re: Technique for increasing depth of field

    Philip,

    It's simply that the plane of sharp focus has been moved to an almost horizontal position. The graphic Michael posted show the principle very well, but let's put that into practice.

    Re: Potassium Ferricyanide question

    My fault, Philip. I thought the link posted earlier was to a video of Barnbaum demonstrating his bleaching technique (I've seen one somewhere, but couldn't find it quickly). It was to an article...
  14. Re: Technique for increasing depth of field

    With the "near-far" focus technique, you should always position the focus at a point on the (nice new) scale you have on your camera bed halfway between the near and far extremes. It makes no...

    Re: Potassium Ferricyanide question

    I use the same stock solutions of potassium ferricyanide (10%) and potassium bromide (3.3%) that I use for SLIMTs for mixing the same rehalogenating bleach esearing mentions. Works well and can be...
  16. Re: Recommendation for a mini-fridge for paper

    Philip,

    I'd go with a small refrigerator, maybe even without the tiny freezer compartment at the top. I got one for cheap at one of the big box hardware stores. You likely don't need to keep...
  17. Re: Technique for increasing depth of field

    Situations like this is where the "near-far" focusing method really helps. Choose the closest and farthest points in the scene you want. Focus on each, note the position on the camera rail and then...
  18. Re: Technique for increasing depth of field

    ic-racer's advice is good. While repositioning the plane of sharp focus in the subject doesn't really increase depth of field (a common misconception here, I'm afraid), it can result in getting all...
  19. Re: Nikkor-SW 75mm f / 4.5 on Chamonix 45F2

    A couple of things:

    First, seeing into the corners with shorter focal-length lenses and a regular skirted loupe is always a pain. My solution has been to remove the skirt or simply turn the...

    Re: Reciprocity - how far?

    The intermittency effect, which also affects stacked exposures made with natural light and a regular shutter. Eight 1/8-second exposures won't quite equal a single one-second exposure. The effect...
  21. Re: Nikkor-SW 75mm f / 4.5 on Chamonix 45F2

    Don't replace your 90mm lens unless it's defective. You'll find that you want them both! FWIW, my SA 90mm f/8 is one of the sharpest lenses I own.

  22. Re: Focusing on the GG: am I missing some optical principle?

    Just a little good-natured ribbing, Bob, since you post regularly about how important it is to get your loupe to focus on the frosted side of the ground glass. Not to detract from the importance of...
  23. Re: would flashing help me in this situation?

    Flashing and burning with a #00 filter have essentially the same effect; to add density but not detail. If you need detail, you need to burn with high-contrast filtration.

    It may be that the best...
  24. Re: Focusing on the GG: am I missing some optical principle?

    So, despite having your loupe focused on the frosted side of the ground glass, your eye can compensate well enough to focus significantly closer than that (and, presumably farther away as well)...
  25. Re: Is this because of light leaking? Or overdevelopment?

    Can't be bellows sag; there would be no image making it to the film.

    It's likely not development either; the line is much too regular. The tank does get inverted, doesn't it?

    I'm betting on a...
  26. Re: Test exposure steps in half stop increments.

    I find it easy to think in terms of "exposure units," where an exposure unit is an arbitrary value that equals the initial exposure. Then you can work with the units arithmetically to arrive at your...
  27. Re: The Wratten Mystery, or, What's My Factor?

    Ha!

    If you think I'm going to see any sun here in Eugene for a few weeks, you're an optimist. Much less a nice clear patch of blue sky opposite the sun. And then there are those pesky mountains...
  28. Re: What’s your most “unpopular” opinion about LF?

    Sure. Let's say I'm photographing in the city, working rather close (think 90mm lens on 4x5), I've got a nice storefront that I'm photographing at an oblique angle. I really like the angles made by...
  29. Re: What’s your most “unpopular” opinion about LF?

    I manage to move the horizon line around in my images just fine with front rise/fall. Really, it's the same thing for the most part as rear rise/fall would be unless you're working really close and...

    Using the blue sky instead of a neutral source will almost certainly result in lower factors for blue filters (I know, not used that much) and higher factors for any filters...
  31. Re: What’s your most “unpopular” opinion about LF?

    I'd love to know more about these field cameras with rear rise and fall... I don't know of any myself.

    I do, however, understand the desire for lots of movements on folding field cameras. I...
  32. Re: How can I construct an inexpensive accent-light holder?

    Gaffers' tape; endlessly adjustable, cheap, small, low-tech.
  33. Re: The Wratten Mystery, or, What's My Factor?

    Actually, the test should be done with a grey card illuminated by nice, neutral 5600K daylight. Note that the color of the object you read with and without the filter will skew the results. Read...

  35. Re: What’s your most “unpopular” opinion about LF?

  38. Re: What’s your most “unpopular” opinion about LF?

    Heck, I just use scissors to cut my 4x5 neg down to panorama to get a 12cm x whatever (depends on how thin I cut it...). Or, sometimes, I just crop when enlarging.

  39. Re: What’s your most “unpopular” opinion about LF?

    Ha! No apologies necessary. Still, I don't think I'd want a large-format camera without movements.
