How Hubble makes its pictures

From the YouTube description:

Hubble images are made, not born. Images must be woven together from the incoming data from the cameras, cleaned up and given colors that bring out features that eyes would otherwise miss. In this video from HubbleSite.org, online home of the Hubble Space Telescope, a Hubble-imaged galaxy comes together on the screen at super-fast speed.

It’s utterly fascinating, and I had no idea. The process seems not that dissimilar to how photographers do HDR images.
