Sony A7R V

This page builds on and confirms the findings in Birch Trees In Winter.

This page uses the Sony A7R V, but applies broadly to all mirrorless cameras, because all mirrorless cameras behave essentially the same way in terms of metering and use of the sensor dynamic range. Particular cameras and settings alter specific details slightly, but the algorithmic behaviors are all the same regardless of brand and model.

Eleven (11) frames were shot in 1/3 stop increments, from +0 (as metered) to +10/3 stops, an exposure range of 3.33 stops. Images were pushed and pulled to match in brightness.

• Camera metering vs perceptual brightness vs sensor potential.
• Optimal exposure failure: how much more exposure could the sensor accept without showing any difference in the converted RAW file?
• Histograms of camera vs RawDigger: just how far off is the camera?
• RawDigger blowout indicators vs usable captures in Adobe Camera Raw.
• What you can do to get the best possible results.

This stuff is what you need to know for ETTR captures.

Don’t miss the super useful tip on using a sub-base-ISO with ETTR.
