I was struck by this Wiki entry. I hadn’t been using the term before, but it seems that this is what I do when I combine several images taken with different exposures… lightening the shadows and deepening the highlights. High Dynamic Range.. hmmm. ‘K.
High dynamic range imaging – Wikipedia, the free encyclopedia: “HDRI provides the opportunity to shoot a scene and have total control of the final imaging from the beginning to the end of the photography project. An example of this control is that it provides the possibility to re-expose. One can capture as wide a range of information as possible on-location and choose what is wanted later.”
