This is one of a number of stray dogs that are readily found in Pulau Ubin, an off-shore island of Singapore. I found this dog resting underneath an old pier, just adjacent to an open-air seafood restaurant. It was friendly and instantly accustomed to my presence. After a few photos it became restless and walked away, but I was fortunate to get some good results from the attempt.
To reduce the impact of background clutter and simplify the backdrop, I used a large aperture for shallow depth of field, focusing carefully on the eyes. The sun was blazing at that time, and light reflected off the sand onto the dog's chest and face, creating highlights in its eyes. It is an example of how pleasing lighting can be obtained in open shade during times where direct sunlight is too harsh for outdoor photography.
