I prefer the b&w and others are already pointing you at the processing possibilities. The pointed rocks at the top I find particularly interesting, looking like caped figures. Think I'd like to see them brought out.
There is a lot to like in both the color, and the black and white, once some corrections are applied. The B/W is very nice so I would choose it without much hesitation.
I prefer the second one if the exposure/brightness were dealt with.
thx. As I stated, the exposure issues are due to viewing the images on a very overbright monitor; on a calibrated monitor the exposures are the way I wanted.
I counted the preferences, color v. B/W: So far, there are 6 votes for the B/W version and 3 votes for the color version (I have only counted votes that showed a clear preference for one version or the other).
