The Bones Of The Image
Sorry about the bad pun, but this seemed like the perfect image to drive home the idea that black and white photographs are more about the structure, tones, lines, and shapes of the photograph, whereas a color image can distract from those basics.
All of the various skeletal segments in the left foreground create lines into the image; they all lead the eye in about the same direction-towards the mesas in the background. The eye then should travel in a kind of spiral: up to the clouds and then back down to the distant double peaked mountain. The focal point (hopefully) is the carcass; the lack of color in the (blue) sky, and the (yellow-ish) grasses means that there is nothing to distract the viewer’s eye from it.
I made this image last year on a trip to the Bisti Wilderness. I had some luck with the atmospheric conditions that day and came away with several very good photographs. This one of the Bisti Arch is one of the best from that outing, and while I think the color version is pretty strong, I feel the black and white conversion says more about what I was seeing and feeling when I captured the image.
Also, the second image has more dynamic tonality; the saturated colors in the first capture the viewer’s attention, but the rich tones in the monochrome version say more about the structure of both the formation and the composition of the image.
