My paying job is nuclear medicine at a local hospital. Basically I use very big cameras to make pictures with radio-isotopes. Put nuclear in front of anything and it sounds important.
Nuclear dog food.
See? Seems important.
We have students at the hospital and I’ve been fortunate to meet many of these people. A few of them have even been kind enough to sit for me after they’ve graduated. One of the benefits of photographing former students is that we’ve had the better part of a year to get to know each other and stronger relationships always make for stronger photos.
