One of my projects is to maintain an online gallery of pretty much every photograph I take which has both of my sons in it. Most are snapshots which would have little to no appeal to anyone besides my wife and I, but I think it will be special to the boys when they get older, and I love looking through it from time to time.
Brian, I just finished reading Streetshooter's thread and can definitely relate to something from everyone's posts and your leaving a legacy was definitely one of them. Is there anyone on this forum who doesn't enjoy looking at photographs of people...but I digress here from this thread's subject. I'll just add that photographs of people can seem almost timeless, yet pack so much history and emotion as well.
I like the expresion of your childs, well captured¡¡¡. I am a "very heavy father", I shoot my girls as always I can. Now they are growing older, and is more dificult, they need to very nice, well dressed, painted......To let me photograph her.
