For years I was the sole family photographer, dutifully recording our vacations and family get-togethers whenever I remembered to bring my camera along. Now I am joined by my teenage son, who has a digital camera. I, alas, am still analog. I love seeing his digital work, and really enjoy using his camera (when I’m allowed.) What’s the best part of digital photography? No film or developing costs to slow you down. Snap away — it’s practically free.
