There is one lesson to ultimately learn from smartphone photography.
"The best camera in the world is the one in your hand," says Alvarez. "And for most of us, it's going to be a phone. Images are moments and they happen and if you don't have a camera, you don't have a photograph."
He says certain things are too personal to be photographed with a DSLR, which is why smartphone cameras are so important — they let you explore your life in a way you wouldn't normally. "Using a phone is very natural and lets you keep a visual diary and go back and see what you were thinking about and interested in."
