Double Processing
Bracketed Effects With a Single RAW File
(5 votes)
Summary
Mike Le Gray shows us how, in this tutorial, we can make a single RAW image into a high range image, similar to when we process multiple exposures.
He explains how double-processing a single RAW file for a bracketed effect is actually pretty straight-forward, using smart objects within both Adobe® Camera RAW® and Photoshop® to blend two exposures. He gives us two ways of doing it, one by blending layers and the other, by using a layer mask.
So jump in and see how to bring out the dynamic range of your photos!

A poor tutorial :(
It is a important subject to learn and I think it´s a poor way to show the technic. :(
