For the history of HDR, the point of it is to use several exposures to fix to a too-extreme range of luminance was pioneered as early as the 1850s by Gustave Le Gray to render seascapes showing both the sky and sea. Le Gray used one negative for the sky, and the another one with a longer exposure for the sea and combined the two into one picture in positive.
I took this picture outside. The first one I took it was sunny outside, the last two it wasn't, which is probably why the first one looks better. I used a tutorial to edit my picture as it is. I learned how to merge the pictures into one HDR picture.
