I recently read about a metering technique Gerald Hirschfeld uses. (Please correct me if I´m wrong)

In "controlled" indoor scenes he´d have a flat diffusor (footcandle) reading of the key light. Using a chart he´d get the T-stop to use.

All other lights (fill, back,..) are set only using the eye (and a contrast viewing glass).
Pro´s are of course fast and easy set-up...

Does anyone use this technique? What are the cons?

If you base your exposure only on the key light, and then add fill, you will be getting more than a "normal" exposure --- If your key is 100 footcandles, and you add 50 footcandles of fill, you are getting a total of 150 footcandles on the fully lit areas of the subject. That's why incident light meters with a "dome" collector that integrate all the lights are widely used.
