Catchlights in Photography
Have you ever asked yourself why some of your pictures look lifeless, boring or empty? Observe the image; check if the eyes of your subject have a catchlight. If it doesn't, consequently it might be one of the reasons why your portrait is visually monotonous.
A catchlight, or better known as eyelights, is referred to the depiction of the chief source of light that makes an unusual glimmer or flicker. This glint could be typically within the eyes of the subject per se. This is a very important ingredient in adding life or tone towards your portrait and can be seen usually at 10 o‚'clock or 2 o‚'clock in the eyes, where it animates your subject most effectively.
