Colors are not just how things are “painted”. Psychology studies color and the way different people perceive it. The way people feel colors describes the way people feel their life. When depressed, or just sad, the world around seems to lack color. When all is great, the colors seem brighter than usual. When taking photos photographers may add an extra meaning to images that helps convey emotions. Color gray is most often associated with depression or bad mood, so in case you want to reflect your attitude to a particular thing or event, you may want to take black-and-white photos. It’s easy to turn your photo into black-and-white by means of the grayscale effect. Grayscale is an image in which the value of each pixel is a single sample, i.e. it carries the full (and only) information about its intensity. Images of this sort are composed exclusively of shades of neutral gray, varying from black at the weakest intensity to white at the strongest. It’s not just your attitude though. Sometimes this effect helps rise special feelings from the viewers. Black-and-white photos do not have attractive color presentations. Their ability to stand out depends only on the photographic communicational skills. They reveal deep emotions, and there is nothing else that matters. Removing color from a photo can add something to it – revealing detail that you wouldn’t otherwise have noticed.
