Dad and new son.
I love photographing dads and their kids. This is especially true of first time dads.
My approach is to never really pose them. What I want is as natural a feel for the moment as possible. Let them spend time together and see what happens.
Of course I pose them as well. But without question, the images that my couples buy are the natural ones that are not posed. Grandmas are especially fond of images of their son interacting with their new grandson or daughter.
