“No matter how good your camera is, taking a
well-exposed photo of a high-contrast scene like a black bird on
snow can be really tricky. Even if you switch to the manual mode
and tweak the exposure settings, there is still a risk that you
will end up with a shot containing under- or overexposed areas. One
way to solve this problem is to use exposure blending. This
technique involves taking several shots of the same scene or
subject with different exposures and then fusing these shots into
one perfectly exposed photo.“While exposure blending sounds simple in theory, achieving
usable results can be a rather laborious and time-consuming
process. Fortunately, digiKam can do the donkey job for you thanks
to an exposure blending tool bundled with the Kipi plugins. The
exposure blending tool relies on the hugin application for
processing and fusing photos, so you must install it on your
machine beforehand. On Ubuntu, this can be done using the sudo
apt-get install hugin command.”
