Description

There are a few other images that show the same cyan color as this one, but the much greater majority are a very different royal blue. It appears that difference is a result of using SCNR, but I’m not sure if green is purposefully removed to “correct” the color, or if SCNR is such a regular part of so many workflows that it’s used without much consideration. The relative strength of my green filter integration would suggest that it really is there, though.
