Exposure Blending with digiKam

"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."
