There's a typo in the first bullet point -- "brightness" should be "brightest"

Thank you.

So the technology behind HDR consists of both gathering more information with you camera (via multiple shots with different exposures), using good math to store the extra information efficiently, and using good color theory to interpret the information you've stored as a pleasing image?

@ak-47 You are right but I don't think the slide mentions efficient storage. The purpose of HDR images are to capture a wider range of luminances that our eyes can capture, and compress that range so that it can be reproduced on a display device such that the reproduced image better represents what our eyes would have perceived in the original setting.
