What is contrast?
Contrast is defined as the difference in the luminance or color of an object in an image. It makes the object distinguishable. It is a tool used by photographers to direct the viewer’s attention to the object. In most cases, the difference is achieved by changing the tons and colors that make the images.
What are the different types of contrast?
Tones are normally described as high, normal or low. High tone images use black and white with some or none middle gray tones. Normal tone images have white, some black and mainly middle gray elements. Low tone images have almost no highlights and shadows. All the elements are of a similar tone.
Color contrast is useful for achieving great composition. Colors that have opposite characteristics to each other contrast strongly with each other. When these opposite colors are placed together they tend to compliment and accentuate the qualities of each other. Color contrast is classified as low and high key scenes. Low key scenes contain mostly dark tones or colors. It is used to depict serious and mysterious scenes. High key scenes mainly contain light tones or colors. It is used to depict the feeling of lightness, cheery scenes, and delicate objects.
