What’s actually in a RAW file as metered?
In the ETTR section of DAP is published a in-depth analysis of ETTR on the Nikon D800E including finished images, the camera information, generous crops and information of the actual RAW data and how it corresponds, using RawDigger for OS X. Examination of the raw RAW data indeed shows that all the prior ETTR evaluations were spot-on.
Next up: practical tips for fast and easy use of ETTR technique. All this technical stuff is necessary to have a thorough understanding (for me and some readers), but in the end one has to be able to use ETTR with low odds of blowing it, yet garnering most of the gain at minimal effort.
