In photography negative space has become a popular technique to give a dramatic effect to the subject. It is used a lot in advertisement so they can add text to the picture and still capture the subject without covering it. It is also used a lot in family/portrait photography to give a different feel.
I didn’t have a lot of time or area to take this picture and it isn’t exactly what I was going for but it is negative space. I do like this picture though, I like his serious look!
