In the 21st century, two major interrelated technological factors have greatly changed how we take photos and how we engage with photography. The first major change was the advent of increasingly affordable digital technology allowing more photos to be taken more often by more people, and cheaper than ever before. I should also mention digital editing technology, which changed the level of control a photographer could exercise over a photo once it is taken. However, this improvement is overstated by those unfamiliar with analog editing technology. It is more an improvement in access than in capacity.
