The Hakuba Red-Eye Pen for Color Prints helps remove unwanted red-eye from your photographs. Simply fill the affected eyes area and your subjects pupils are as good as new.
Red-eye can occur when a photograph is taken of a person in a low light situation. The iris of an eye tends to open when its dark, to let in more light. When a cameras flash is set off the light floods the wide open iris hitting the blood vessels in the back of the eye which produces the red-eye effect.
Hakuba's line-up of photographic pens are intended to serve the varied needs of professional and amateur photographers, designers and artists who work with prints and transparencies.
