Paul C. Buff “Einstein” Lighting Test

Paul C. Buff “Einstein” Lighting Test

Lighting Test

I bought a used Paul C. Buff “Einstein” (model E640) studio strobe just before Christmas; the package arrived on New Year’s Eve. So far I really like it; I’ve been trying different settings, modifiers, distances and so forth. I took this self-portrait with 2 lights: the Einstein, plus an inexpensive speedlight. Here’s the setup:

  • Subject distance from both lights ≈ 8′
  • Einstein is to subject front & left, ~7′ up, with a 43″ silver “bounce” umbrella angled at subject
  • Yongnuo YN 560 III is to subject front & right, ~5′ up, with LumiQuest Softbox III aimed at subject
  • Einstein is set to 5600K at ƒ/-5.0
  • Yongnuo is set to 132 power & 24mm focal length
  • Camera distance from subject ≈ 1 meter (3′ 3″)
  • Lens = Leica Tele-Elmarit-M 90mm ƒ/2.8 Nr. 11 800
  • ISO = 160
  • Shutter speed = 1180 second
  • Aperture = ƒ/2.8

The images are 80% quality JPEGs with basic tonal adjustments.

I don’t have a power pack or Paul C. Buff triggers or transceivers yet, so the light was running on AC power and I fired the flash with a Yongnuo transmitter and 2 Yongnuo receivers.

About the Featured Photograph(s)


M-mount lenses do not provide aperture information to the camera body, either electronically or mechanically. Therefore, f-stop settings are approximate, and are probably wildly inaccurate. For what it’s worth, I usually shoot with my lenses wide open.
