Fujifilm GFX100S: ETTR at ISO 100/50, Histograms and More (Birches in Winter + Color Card)
This page is aimed at RAW shooters. It explores ETTR practices for the Fujifilm GFX100S using 16-bit captures at ISO 100 vs ISO 50.
RAW capture or RAW+JPEG is presumed with the intent to process RAW and discard the JPEGs (even so, shooting RAW+JPEG is useful for superior image review in camera).
- ETTR exposures from +0 to +5/3 stops at ISO 50 and 100.
- Proof of equivalence of ISO 100 vs 50.
- Camera RGB histograms for Live View and captures and how they correspond to real RAW data as with RawDigger.
- Recommendations for ETTR shooters.
- Usability issues for ETTR shooters.

Includes screencast video walkthrough.
Similar findings apply to the rest of the GFX100 series. The Fujifilm GFX100 II has a bit better quality with its real base ISO of 80, but the same behaviors should be seen there.
