What is Exposure Fusion?
Lets set things straight from the start, Exposure Fusion is not a kind
of HDR.
Exposure Fusion is a fairly new concept that is the process of
creating a low dynamic range (LDR) image from a series of bracketed
exposures.
In short, EF takes the best bits from each image in the sequence and
seamlessly combines them to create a final 'Fused' image. Or more
technically, the fusing process assigns weights to the pixels of each
image in the sequence according to luminosity, saturation and
contrast, then depending on these weights includes or excludes them
from the final image. And because Exposure Fusion relies on these
qualities, no exif data is required, and indeed, if you wanted to, you
could include an image with flash to bring darker areas to life.

[...]

For one, no intermediate HDR image needs to be created

, and therefore no tone mapping step is required either,
========================================

making Exposure Fusion a far more efficient and quicker process. Not
only that, but due to the algorithm used in Exposure Fusion, halos
around objects that would otherwise ruin a nice HDR image have been
completely eliminated, resulting in a more natural looking final
image.
