Ever wondered how the CMOS and CCD image sensors inside cameras work? Well, these neat animations by Raymond Sirí do a great job of explaining it.

The animations show the basics of how the two sensor types capture light, make sense of it, and then send it off to be stored as an image. They were, according to Sirí, made for use in a trial against Canon. But let’s not let that bring us down. The biggest takeaway from the videos is how CMOS sensors capture one row of light while CCD sensors capture it all one go. Take a watch!
