Luminance HDR¶
While doing some investigation on HDR-Software on Linux I stumbled over Luminance. A quick on-the-desk test should quite acceptable results. So far I haven’t been outside to shoot a proper subject. I’ll do this later…
The basic on HDR is quite simple: Shoot a couple of identical images which just differ in the exposure time, so that one has the correct exposure and the others are equally over respectively under exposed.
In a second step these images are aligned and merged to produce a new image with the highlights and lowlights of all the original images. That way you create an image with a higher volume of details than _normal_ images.
If yo actually like those images is a personal matter of taste.
Installation¶
You can of course download the sources and try to compile them. I had some issue there (especially with cmake). The dependencies you need are:
$ sudo apt-get install qt4-qmake libexiv2-dev libopenexr-dev fftw3-dev libtiff4-dev libqt4-dev g++ libgsl0-dev libraw-dev libpng12-dev cmake liblcms1-dev
Or you can install it from the GetDeb Apps repository (which is much easier):
$ wget -q -O - http://archive.getdeb.net/getdeb-archive.key | sudo apt-key add -
$ sudo sh -c 'echo "deb http://archive.getdeb.net/ubuntu precise-getdeb apps" >> /etc/apt/sources.list.d/getdeb.list'
$ sudo apt-get update && sudo apt-get install luminance
Ready made packages for Windows and Mac are also available,
Usage¶
A step-by-step tutorial on how to use it would blow the range of this post. And there are enough on the internet anyway. So don’t be lazy and search for yourself. It’s not that complicate either.
