Let's say I want to take a picture from inside an office where both the room and the view outside the window are equally bright (e.g. like this). The easiest way to pull off that shot is to shoot a series with exposure bracketing and stitch the result later in Lightroom or Photoshop. It's a straightforward processing especially when dealing with perfectly static subjects.
But how do I figure out the optimal number of shots and the exposure bracketing distance between them? Should I take 3, as my camera would by default in bracketing mode? 1 stop difference between each shot or aim for less? Is there a set of rules I can follow to achieve perfect HDR shots?
