A Catch light is a white spot in a person’s eyes and is key to make the person look alive. Without it, your subject’s eyes can end up looking a little lifeless and flat. To my opinion, faking it successfully is nearly impossible, and therefor to be applied when taking the photo. The type of catch light you have will depend entirely on the main light source. I use the Rotalux® Softbox Octa 100 cm. As a general rule of thumb, try positioning the light source so that either the catch light falls at the 10 or the 2 o’clock position within the subject’s eye and high up so the soft box has the viewpoint of a natural sun facing down on my model.
