Yeah, that's what I do these days, and for me it works about as well as what I used to do. That still doesn't explain the change that's turned WB adjustments from a reasonable way of tuning B/W conversions into a total horror. It doesn't matter much, though; I'm just curious. > The post Anders links to describes only what happens when you increase > saturation. Ah, right. It does seem rather more sensible that saturation beneath 1.0 be linear. > The BW conversion in the exposure mask is pretty simple: > > out_rgb = (in_pixel[R]*3 + in_pixel[G]*6 + in_pixel[B]) / 10; Ah, thanks. I'll use that as a reference if I find that the exposure mask looks like a decent B/W conversion.
