The human eye responds to a wider range of light
than film. Modern digital camera sensors suffer
from less range of light they can capture.
HDR photography is a system that enhances the photographic
image which can created the whitest whites and blackest
blacks in the same image without clipping. Software
combines at least 2 exposures of the same image (generally
3 or more expsoures). Through an algortihm,
they are tone mapped and saved in a format the monitors
and printers can handle.
The technique can result in vivid colors and some
detailed photos. The process can also result in
some very surreal photos.
I will attempt to discuss the technique, software,
and processes that I have investigated and used.
