I'm still somewhat confused, does HDR combine different exposure rates to achieve a well-lit image? Or does it set up the proper exposure window to take the image beforehand?

Basically is it a pre or post process?

How does HDR find the best parts of multiple photos and combine them? Is there some sort of algorithm or threshold for what makes a certain image well-exposed that a camera can recognize when putting together the final image?
