A headshot is a photographic technique where the focus of the photograph is a person's face. A headshot is a specific type of portrait. A headshot is an image that portrays a person as he is, however simple or stylized the image might be. In contrast to the head shot, an environmental portrait would portray a person with elements of his life such as his work, interests, etc. Head shot photographs are often used for identification purposes. They are generally front-on (facing straight at the camera) photographs, with the face being in the centre of the picture and containing minimal or no surroundings. The facial expression is usually neutral and often require the temporary removal of facial accessories such as glasses.
Head shot photographs are used as passport photos, mug shots and on other forms of photo identification, such as driver's licences, student cards, security cards and at times on credit cards.
   The Head and Shoulders formation is one of the most well known reversal patterns. On the technical analysis chart, when a price trend is in the process of reversal either from a bullish or bearish trend, a characteristic pattern takes shape and is recognized as reversal formation.
