Many times you see a beautiful scene and of course you snap
a picture! The result is often far from being the magical
scene you carry in your head.

Our eyes are very adaptive and they are also more sensitive
to intensity than color. It is estimated that our eye can
see over a dynamic range of nearly 24 f-stops while a
digital camera can capture a dynamic range around 6 to 9
f-stops.

The High Dynamic Range Imaging is a set of techniques that
has been developed nearly 20 years ago to overcome the
limitations of electronic devices by combining multiple
exposures into one great looking image.

A HDR photography can be created by taking few photos with
different exposure, then combining them in the software
into a high dynamic file. The last thing is to tone-map the
HDR image so we can see it in our screen, print it, post it
on the web and enjoy.
