Digital single lens reflex. If you don’t know cameras the initials stand for big serious camera with interchangeable lenses. …if you care. Go on. Use that iPhone… I always considered myself to be a serious amateur photographer. May 25, 2004, I received my Nikon D70. I opened the package near midnight. Yes, I worked late in those days. I like to say it was the last time I shot slide film from that day forward. It pretty much was the case. Digital was seductive and in my head I had a quality camera capturing the images that would be comparable to slide film with way less processing. Of course, the rest is history. I have been through several iterations of DSLR and now am using advance point and shoot cameras. The iPhone remains a distant (second) device though for many it is the camera of today. iPhone is $1000 as are advanced point and shoot cameras like the Sony RX100. Each has a purpose. I believe a camera dedicated to a single purpose is better than a smart phone.
