Exposing for B&W digital?
lowep:
Should any different in camera exposure settings be used for capturing a RAW file intended for converting and processing as a B&W image than for a color image, or is it just the same as photographing color?
razrblck:
Same settings, except that I might be able to use higher ISO or push shadows a bit more since noise is less noticeable and color artifacts more or less disappear.

That sounds reasonable
stamper:
A camera doesn't see colours only luminousity values, therefore a problem doesn't exist.

Hi,
In everyday practice, the same exposure will do.
When pixel peeping, technically there could be a (small) benefit from shooting through a somewhat magenta filter, to compensate for the denser Red/Blue filters in the Bayer CFA. That would require less boosting of those channels which would help to reduce noise a bit.
The amount of difference also depends on the final postprocessing, and how image colors are used to change the tonal balance.
Cheers,
Bart
