The first camera to capture a permanent photograph/Inventions & Discoveries
Louis Daguerre announced the daguerreotype process in 1839, creating the first practical photographic method. The camera itself resembled a large wooden box about 30 cm long, 25 cm wide, and 25 cm tall, weighing roughly 5 kg. Exposure times initially required 15 to 30 minutes of perfectly still sitting, though improvements reduced this to under a minute. The silvered copper plates produced eerily detailed, mirror-like images that still astound viewers today.
Early models, about 15 minutes
