History of Photography
PHOTOGRAPHY was invented in the 1830s. Before that, the only way to "save" what someone looked like was to PAINT a portrait — slow, expensive, and done from memory. The first photo to capture a person, taken in 1838 by Louis Daguerre in Paris, was a stunning breakthrough. Suddenly, the visual world could be frozen.
Major eras. DAGUERREOTYPE (1830s-1850s): single-image plates, very long exposure (people had to sit still 15+ minutes!). FILM (1880s-2000s): rolls of light-sensitive material — Kodak made it accessible to everyone with "you press the button, we do the rest." DIGITAL (1990s-): electronic sensors replace film. SMARTPHONE (2010s-): photography in everyone's pocket. We now take more photos in 2 minutes than the entire 19th century did combined.
Why did people in early photographs (1840s-1850s) look so SERIOUS?
Photography changed everything. NEWS: people could SEE wars, disasters, daily life across the world. SCIENCE: pictures of cells, planets, microscopic particles. ART: a new visual medium. FAMILY: ordinary people could keep visual memories. POLITICS: photos shape opinion. SOCIAL MEDIA: today, photos are how billions of people communicate every day. The smartphone in your pocket continues a 200-year revolution.
Old Photo Hunt
Find a photo of a relative from 30+ years ago (a parent or grandparent at your age). Compare it to a recent photo of you. What looks similar (genes, smiles)? What looks different (clothes, technology, places)? You're looking at family history.
Every photo is a tiny time machine. Knowing the history makes you appreciate what a remarkable invention you carry in your pocket.
