photography

The camera evolved from the camera obscura to chemical photography and digital sensors. This guide explains the chain of inventions.

From Niépce's 1826 pewter plate to the CCD sensor that won the 2009 Nobel Prize — how photography evolved from a chemical curiosity into the most used technology on Earth.

How digital camera sensors turn photons into pixels: photodiodes, Bayer filters, CCD vs CMOS, pixel size, noise, dynamic range, and computational photography.

When photography arrived in 1839, painters feared for their craft. Instead of ending painting, the camera changed what painting was for, and art has traded ideas with it ever since.

Drones range from 249-gram camera quadcopters to 27-hour military aircraft. Here is how they fly, what sensors and software keep them stable, what the rules say, and what delivery and air taxis can realistically do.
