High Dynamic Range Imaging
|
HDR imaging is the
newest trend in digital imaging, despite having it's roots in the
earliest photographs and even renaissance paintings. In a nutshell, HDRI
is an attempt to capture images that more closely match what the human
eye can see and what exists in reality. Unfortunately, even if these
images could be captured there isn't any way for consumers to view the
images on their screens or in print. This is where tone mapping comes
into play. By compressing the data from the highlights and shadows into
the middle tone areas, the image has details in both of these areas that
would have not existed in a standard image. The tradeoff for this
additional detail is a somewhat surrealistic image that happens to look
cool, but perhaps at the cost of realism.
HDR images can be produced in a number of ways. Personally, I use Photomatix for OSX to combine 3 RAW files across 5 f/stops (0, -2ev, +2ev) |
