Do you remember the first photograph you took? I guess I am thinking of one taken due to an interest in cameras and photography - i.e. not a snapshot taken at age eight when you bugged your parents to let you take a photo with their camera while on vacation, or something like that. But feel free to define "first photograph" however you would like.
My first photographs were taken with a Kodak Instamatic 110 camera in 1975, at age 12. We were about to drive to Washington, D.C. on a family trip that summer and I found the camera in a drawer and asked if I could take it with me. I was told I could, so while in D.C. I used up one or two rolls on the typical tourist shots - the White House, the Lincoln Memorial, the Capitol, etc.
That sparked an interest in photography. Over the next few months I asked my dad a lot of questions and he showed me how to use his Retina rangefinder and Topcon SLR. That Christmas I was given a Ricoh G rangefinder, my first camera. The first photo I took with it - on Kodachrome (my dad always shot slides) - was of my little sister, taken on the day after Christmas.
I shot my first roll of b&w print film (Tri-X) in 1977. The first photo on the roll was of a possum hiding in a bush next to our house.
I no longer have either the Instamatic photos nor those Tri-X negatives - I am not sure what happened to them. I do have the slide from December 26, 1975, and generally consider that to be my "first photograph".
