This article could be easily called "Shoot once, Use twice", because this article explains how to use a single RAW file to get most data out of it. Usually the dynamic range of the camera (or JPG file) doesn't allow capturing all the details in highlights or in shadows. But the RAW files have this information and a few steps would allow us to retrieve and use this information. That's why we are going to create High Dynamic Range (HDR) file using Smart Objects.
