In the previous post we looked at color shifts in pushed Sony a7RII images, with push amounts from nothing to +5 stops, which is all you can get with the Lightroom Exposure control. See that post for the details of the conditions under which the images were captured.
Now, I’d like to present blowups to slightly under 200% of an area in the scene containing both highlight and shadow information.
There appears to be slightly more noise in the ISO 100, 200, and 400 images than in the other three, with the effect especially visible in the ISO 100 image.
For a really tough deep shadows test, we can look at some of the darker tones in the Sekonic step wedge.
The same pattern i there, but is easier to see.
huh? This goes against all logic
Counterintuitive for some folks, but true.
