This is another great time saver. Compare the color and B&W versions, below. I tweaked a preset slightly for contrast, blacks, brightness, and what Nik calls “structure” (mid-tone sharpness, similar to what is affected by the clarity slider in Lightroom).
I happen to like the presets.
The “simplification” B&W images offer is very appealing. I don’t consider myself a B&W photographer and like color in my images (why I shoot Sony), but on occasion it does strike a chord.
