Photo portrayals are more than images: they are mirrors of a person’s distinctive physical characteristics, personality and feelings in a given situation.
By using different photographic techniques one can portray a person’s unique traits while meeting his or her own taste.
Some people prefer colored photographs which use the subject’s own body and garments colors to represent his or her own style and beauty. The colors of the background and of other objects enrich the photographs of nice shades and details (think about photos at sunset or photographs at sunrise).
Black-and-white photographs, on the other hand, add a kind of ‘eternal’ flavor, as if the image was taken out of time. The ‘noise’ of the colors is not there and the focus is more on the subject’s physical traits (such as the face details or the body shapes) and the look of his or her eyes.
It is sometimes amusing to photograph the same subject with both techniques and let him or her choose the preferred one… or perhaps both of them.
