Hello<br>I agree with david. Of course, B+W converstion can be adjusted/reworked on the PC. But most dslr have *many* ways to do B+W and especially when you shoot monochrome, it is nice to see your result on the spot. The good thing about raw picture is that none of the adjustment is done to the raw file (but it is of course done to the jpeg file if you shoot raw+jpg). So if you are not using a proprietary software, your raw file will never be decoded just like your camera would have done. <br>
Maybe it would be good if digikam could try and mimic these in this aspect but I think it is really difficult. It has to be able to decipher the exif tags (what exiv2 does not fully do) and then apply camera settings for accentuation, constrast, luminosity, filter, turn (reading my b+w menu) and then reproduce the effect accordingly. You will never get the same result your camera/official software internal opaque magic would have produced and I'm not sure it's worth the effort: you can do it yourself... Perhaps not with digikam that is not meant for raw photography but rawtherappee ? (rawstudio, gimp,... ?)<br>

I would strongly recommend to do the B&W convertion ON THE PC! Every digital camera has only one single way to convert color to B&W. On the other hand, when you work on your PC you have numerous different ways to achieve the exact result YOU want, and not the one -almost randomly- generated by the camera....<br>

Hum. As operation are preprocessed to convert RGB to B&W, and curve
applied to B&W, this is a non sence to have RGB curves there.
Typicialy, curve is just to adjust brighness for high/middle/low
levels.
