The first "cameras" were simple boxes that focused light through a pinhole, creating an image. By the 15th century, quality glass lenses could be used to focus these images, and by the 19th century chemicals such as silver nitrate allowed a permanent image to be preserved, establishing the modern science of photography.
In many respects, cameras were developed, rather than having been invented by just one person. In 1685, Johann Zahn described, but could not build, a magic lantern device that would capture images. Nicephore Niepce used bitumen to create the first actual photograph in 1825. The first practical portable camera was built by Louis Daguerre in 1837. The first camera that was practical for everyday use by ordinary people was invented by George Eastman in 1888.
Some say the first 'camera' was designed before Christ. It was by simple deduction that an artist noticed a faint image on the opposing wall of a small building where a small hole let in light from outside of the building. He worked on a lens that could be placed in a similar hole of another building and he noticed that the image on the opposite wall was rather clear, color and all, although upside down. He then proceeded to use oil paints that were in use to paint portraits at the time. He simply mixed the oils to match the colors and painted directly onto the image he was looking at.
(Today's cameras do the same thing minus the oil paint. Film cameras have replaced the oils with both silver halide salts and dyes. Digital cameras simply use super miniature diodes, photo-etched onto silicon chips, to translate different ranges of the color spectrum into digital code.)
This "camera obscura" technique allowed artists to draw detailed images of scenes from real life, or of other still images.
