Back in the '80s, a new technique called osseointegration was tried out at our hospital. As the inservice coordinator, I had to ensure my OR staff knew each and every step of the procedure. During the inaugural surgery, I photographed each step of the operation both with the surgeon's camera and my own. I had mine developed as prints and slides so they could be used as teaching tools. Years later I photographed back-tables, endoscopic procedures, unusual cases and whatever could teach anyone else. As I became more familiar with depth of field, macro lenses and lighting I would photograph everything including x-rays and use reverse B&W development for some . In every instance, patient identification was impossible as I never recorded patient info except for the diagnosis and treatment. Nothing was photographed which could be connected directly to a particular patient. The sequence itself was paramount to the photographic element. As a circulator, the patient was my priority, but if a photo opportunity arose that I could use presented itself without jepordizing the patient, I would take it. As a caveat, any permit which did not state photos were allowed were eliminated from any photographs, even if unidentifiable. John
