  • HDR does not improve the quality of an image.  It combines multiple images of the same scene using different exposure levels, to produce a single image with higher dynamic range.  Such an image has to be stored using a special file format.

    There is some description of the algorithm here https://en.wikipedia.org/wiki/Tone_mapping, but it doesn't have enough detail to implement anything.

    You will probably need to look at an existing open source solution to figure out the algorithms, and then go implement your own.  Frankly, that's a lot more trouble than using an existing, tested library.
