According to a number of web-pages, including, National Day Calendar, (AKA NDC), June 29th (which is today) is National Camera Day. One of the things NDC states is "... This day commemorates photographs, the camera, and their invention. A camera is an irreplaceable tool used to record and replicate memories, events, and people/places..." I find it interesting that NDC considers one of the purposes of is to "replicate memories..."
Many of my childhood experiences of being photographed for a family picture seemed be that the intent behind the camera wasn't replicating a memory of what was occurring, rather, it was to creatue an ideal which wasn't there. For example, in the following picture I can be seen (at the far right) with my family.
We are all seated on our front porch, the front porch my father constructed when he built our house (that we ultimately lost when our family came apart), the house which my grandfather, who was an electrician wired; and, we are looking quite like the family living the American dream, which could not have been further from the truth! My father moved away soon after that Christmas card photo was taken, which resulted in my mother 's proclaiming (for years to come) how much she hated Christmas, and for years to come she did send cards.
