Smile! National Camera Day is June 29, a day to celebrate the fact that photography, once so complicated it took a scientist to understand, is now part of our everyday lives. The word “photography” is based on two Greek words that, when put together, mean “writing with light.’” It’s a beautiful way of describing what a camera lets us do — tell a story without the use of words. It all goes back more than 800 years to the invention of the camera obscura. Meaning “dark chamber,” the camera obscura was nothing more than a box with a hole on one side. Light would pass through the hole and into the dark interior of the box, where it would project an image onto the flat inner surface. Unfortunately, when the light was gone, the image disappeared — like Instagram, but without an actual photo. Fast-forward through the centuries to today, when everyone with a smartphone has a camera at their fingertips. Whether you love shooting film and changing lenses or prefer the ease of digital, use June 29 to focus on how cameras have made telling our stories easier than ever.
