You could make up lots of stories about this photo. It was really about the determination to keep on walking and having the energy to get to the end of the trail in spite of having difficulty walking. The fog created an interesting mood to the photo, like he was walking toward the unknown.
A quick photo tip is to use a touch of red or yellow to make a photo really pop. (like a red umbrella, T shirt or jacket) Since there was so much green in this photo, the bright blue jacket really seemed to help lead your eye to the subject and the fog created an uncluttered background, while the trees made a nice frame around the subject.
Yes, you may have seen this photo before on August 21, 2011 blog.
