The way I use ETTR is:

  • Determine through testing how many stops above the meter reading saturation of the first channel occurs. I do this by taking images of a gray card at various exposures and plotting the raw values of the three channels.
  • With this knowledge I spot meter the important highlights - the ones I need detail in.
  • I use Zone System to "place" important highlights below saturation.

Spectral highlights do not need to be placed below saturation - only those that I need to retain detail.

Note that I only do ETTR when I have a difficult subject brightness range and need the precision. Most of the time Av or Tv modes are adequate.

Would it not be much simpler to bracket the exposure and pick the appropriate one retrospectively?
