I prefer the first shot with the three runners out on a cold, frosty day. With the three runners removed, the visual payoff is scant....looking several hundred yards down a dark tree-covered path and the visual payoff is 10 percent of the frame filled with brush and grass? Uh, no....not worth the payoff for me. THe one with the people in it is visibly more compelling.
I think what would be interesting would be to post the two images, side by side, on pBase, and see, over a month's time which image garners more clicks. DOllars to donuts, it will be the image with the people in it.
Still, with the people removed, you DO have a picture. it's a different picture than the original, but the rationale for the picture without people seems less compelling. Still,an interesting exercise, no?
