It is said that a picture is worth a thousand words as it has the ability to capture the unspoken. It can also convey your feelings faster than words. As American photographer Aaron Siskind once said, "Photography is a way of feeling, of touching, of loving. What you have caught on film is captured forever… It remembers little things, long after you have forgotten everything."
