New recommendation: If you can use an MR16 bulb, SORAA “Vivid Light” MR16 bulbs seem excellent, comes in 3K and 4K, but these two may not be that different. With my usual testbox, SORAA bulb, and NLP 1.31, I think I have the best auto conversion yet.
Previous winner for illumination was the iPhone 7 (8 and X have same screen). Here’s a comparison, both with NLP 1.31, Frontier, Film=Fuji, and then Brightness to -6. Otherwise Auto. Both are slightly warm (not corrected).
