There are lots of elements I consider when taking pictures. There is the camera and the lighting,... the background and the subject... the ability to edit...and there's having the eye for what will look good.
But there's more...
I think you can see in pictures when a photographer "gets it". When a photographer gets it, you can see the personality of the child, almost hear the giggles from the toddler, and feel the love that the newlyweds share.
I strive to do my best at all of the above. Above all, though, I want to "get it."
