    Re: Darkroom Sink Slope & Drain?

    My sink is that size. I built mine flat and level and adjusted with blocks under the legs. It's about 1/8" per foot and it's plenty.

    With a router, cut a relief for your drain flange so it is...

    Re: How Many LF Formats Do You Use/Own?

    4x5 Chamonix, 5x7 Deardorff, and 8x10 Deardorff. I haven't done much with any of them since the Damndemic. And the 8x10 is up for sale soon. I agree with Kirk.

  5. Re: Smarter material for ground glass shim?

    I used black paper. It was a heavy stock, probably 2 point. It can be sanded or peeled thinner if needed. Or it can be stacked; glued with rubber cement, if thicker is needed. A piece of film...
  6. Re: When do aspherically ground lenses date from?

    The Schmidt corrector plate is an aspheric surface with a 'wave shape' cross-section. Originally used in some telescopes, it is now used for other applications. About 100 years old.

    Re: How about some infrared images

    Self portrait. Actually a 5 sec movie in mid-wave infrared (4 to 6 micron) taken with a camera I designed in 2011. So yes, it is digital and I have sinned.

    All my Deardorffs, 3 of them, needed the ground glass repositioned. I did it by measurement, but photograph a ruler with small f/# works too.
  13. Re: Schneider Super Angulon 72mm XL - filter conundrum

    Only saying that as one stops down, the radius of use of all the elements stops down too. At 5.6 you need the full front element. At f/22, the image is no longer in the outer fringes of the glass. ...

    I use 4" gels (poly) with mine. Either handheld or in a Lee snap holder. Unless you are using f/5.6, then your image rays don't go through all the glass and your filter doesn't have to cover...
  15. Re: Anybody used condenser lenses to build a taking lens?

    Try it. If you like soft fuzzy. These lens are probably cast, not ground, so the surface curvature could be anything.

    Re: Butane for developer preservation

    breath still has much oxygen. We are not efficient about the conversion because CO2 is poisonous to humans. CO2 is acidifiying, but not much. Ask the coral.

    Rectified AC is just higher frequency w overtones. Basically a mess unless you filter or regulate.

    Buy a 120vac coil w DC contacts. A 'contacter' is such a device. Check contact currents.
  19. Re: LED enlarger head questions, elgatosuizo's design

    Dry relay easiest. Check your ratings.

    I used a PFET and an opto coupler. Tricky business.

    Whatever. You want ground isolation from unit to unit.

    Re: Point Reyes Advice?

    Two days? Don't take so much gear. You'll spend your time figuring what to do, rather than doing it. Whichever camera you take, you'll have plenty to photograph.
