a random pup dashing off into sun... camera was pointed into the light with a negative exposure value, hence the overall darkness and rim-lighting... colour added in LR i think... i think it rather ruins the shot, but whatevs... rainbow...
(works well on black if you can get past the day-glow colouring)
love the trail of dust giving the image depth and the sense of movement. The rim lighting is great - I can see why you might want to stick with the black and white on this one.
