So here's what I do.

  • Insert the film into the 4x5 holder.
  • Insert the step tablet over top.
  • Turn on your light table.
  • Take a meter reading off the light table.
  • Add 4 stops. Set the shutter/aperture.
  • Focus your camera to infinity.
  • Add a filter or filter adapter ring to the lens, and ** gently ** lay the camera lens down onto the light table. (yep that's what I do.)
  • Take the photograph.
  • Repeat.
