I prefer the colour! Thanks for showing it.
Originally posted by Ash The B&W version is fine, but the conversion is quite flat. Dull and lacking in the right tonal range in the desaturation. I'd suggest to use the dedicated Black & White conversion tool and manipulate the reds and yellows carefully to get the right contrast and textures in the skin tones, where you'd want accentuated in such an image.
The Photoshop B&W Adjustment Layer works very nicely for this.
Or one can directly manipulate the colour channels, in pretty well any software going.
There are lots of methods to try. I read a magazine article some time back that described about a dozen different ways of doing a mono conversion. Just sucking out all the colour is the least likely to yield anything decent.
