Thing is Hurts, that by removing the color palatte, you remove that segment of information from the image, forcing the viewer to concentrate more on the cintent and compostition of the image itself.
I have a lot of pictures at clubs where they look good simply because of the colors that are present from the lights and things, but the image itself, the person, form, line, shape, narrative, etc., is not there.
Likewise, I have many photos where the colors don't really matter, they are more like icing, or (to go with a food metaphor) the presentation and garnishment of a fine meal. The actual food itself should be able to stand without the garnish and presentation.
Now, as to Boog's photograph there, I would say that a lot is being said, and to a degree the color may detract from the image itself. Often times by taking an image into B&W, you make a person view the scene in a different state of mind. Thus, they will look at a scene and examine what information comes from the setting, expression, body language etc.
And finnaly, before my drunken ass passes out, I thought it would look wonderful as a B&W(since it is still my favorite medium) and did so. All credit to Boog for the pic. All I did was a little greyscale conversion, contrast, and crop, and this is whatI came up with:
But enough of such things, my drunk ass is going to bed.
