The Science Behind Camera Sensors

Photography Tips

Have you ever wondered what the process is behind classic film? How does exposing light to a thin slice of coated silver bromide create replicas of what’s in front of the lens, and how did digital technology mimic that? For all those answers and a head-spinning amount more, check out this quick 10-minute video lecture on the science behind camera sensors:

The video is swiftly hosted by John Hess at Filmmaker IQ. We’d try to summarize any of it here, but Hess is basically condensing a large, dense textbook into a 10-minute lecture, so it’s probably best if you just watch it.

It deals specifically with the development and origins of black and white film, and then extends into how modern digital CCD and CMOS sensors have replicated that technology.

Enjoy!
