In the way of background, I’m a Gastroenterologist: I photograph the insides of patients using endoscopes. Going farther back, I took a one-year photography course my junior year of high school. During senior year I was the yearbook photography editor. My instructor those two years taught me both basic and advanced techniques of film photography.
Since then, I’ve photographed weddings, baptisms, sporting events, social gatherings, pets, children, architecture, parades, nature and wildlife. My current interest is nature and wildlife photography.
Though some photographers still shoot images using film, 95% of professional photographers have switched to digital cameras. One of the biggest benefits of shooting digitally is the ability to take lots of images without having to change image storage units.
This is great when shooting wildlife, since the opportunity may arise when a critter (or critters) is doing something so interesting that the photographer doesn’t want to chance running out of “film.”
Back to nature/wildlife: the goal of most nature photographers is to catch that “great” shot. A lot goes into that. Some of it is luck, having a camera in hand and just being at the right place at the right time with the right lighting and the right camera settings.
Another part of it is knowing the basics of photography. Taking a good photography class is probably the best way to learn the workings of a camera. A hands-on approach helps a lot. It’s more challenging learning from a book. Nowadays, though, internet tutorials can be beneficial.
