In photography light is the most important element. The word "photography" derives from the Greek language and means, literally, “light writing.”
My favorite time of day to take pictures is early morning or late afternoon because the light is always rights during these times of day. In the middle of the day, when the sun is too high in the sky, the light can come across as very harsh on the image. In the wrong light, even the most wonderful location can appear ordinary in a two-dimensional image. The warmth of early morning and late afternoon light illuminates and enhances a photograph. Harsh, overhead light is rarely complimentary to any scene. The afternoon light in Buenos Aires is something that must be seen to be believed. It's almost magical.
