I remember sitting with my parents and siblings and being told the stories about the people in the pictures. The photos were great visuals, but more importantly, they sparked wonderful stories of times that came before me or that I couldn't remember.
There were laughs and there were tears, all brought about by some dog-eared black and white photos with scalloped edges.
Let a professional photographer capture these memories for you and then let them be printed. Hang them on walls, have them bound into books --- they're the laughs, tears, and wonderful stories of the future.
