Nice - thank you! I don't see the f/stop value. Unrelated, I cannot help wondering what -0.7 exposure compensation does at ISO 100? The SS was 1/10 s for the second image. Would changing this to 1/15 s be better than applying -0.7 exposure compensation when the camera is at its base ISO? Of course, the images are gorgeous, and my question is of purely technical nature - no criticism implied.
No problem! Here is the camera info in order I posted (all with the A7R III):
f/13, 20s, ISO 100, Aperture Priority
f/11, 15s, ISO 100, Aperture Priority
f/9, 1.6s, ISO 100, Aperture Priority
f/13, 1/10s, ISO 100, Aperture Priority
To you question, the 1/10s shutter speed IS the shutter with negative exposure compensation applied. If I did 1/15 or shorter it would be "greater" negative exposure compensation i.e. -1 EV or more. I am using exposure compensation here because I am shooting in aperture priority rather than manual. The reason here is that the light levels were increasing every minute or two as the sun was rising. Letting the camera choose the shutter was quicker and I usually find with this camera's metering shooting in HLG that applying some negative exposure compensation is necessary to protect the highlights.
