This may seem like just another shot to most people but you could take a closer look before reading my quick explanation below.
To begin with, I'm sure many of you would have seen Michelangelo's "The Creation of Adam". I'm not saying this photo is comparable to it in any way, but in the painting, God breathed life into Adam when they made contact. In some ways, the parallel is drawn in the photo as well, when life is handed to the elephant in the form of food.
Also, everyone knows that the size of an elephant would probably dwarf that of a child. However, the child in this photo is certainly standing much higher than the elephant. This corresponds the belief that most humans possess - that they are superior to other animals which inhabit our world.
Lastly, even if I hadn't mentioned that the subjects were an elephant and a child, you could have easily guess it as well, by just looking at parts of their bodies.
You may or may not agree with my explanation but this is how I felt when I looked at it myself. Cheers!
As for the technical aspects of this shot. I must say that it is suffering from a little motion blur since the trunk was really moving too fast to totally freeze it. Too bad I don't have a fast telephoto with me.
