  1. 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. ...
  2. Re: Schneider Super Angulon 72mm XL - filter conundrum

    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...
  3. 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.
  6. Re: LED enlarger head questions, elgatosuizo's design

    Buy a 120vac coil w DC contacts. A 'contacter' is such a device. Check contact currents.
  7. 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.

    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.
