I am a great fan of HDR photos and i process a lot of my photos on HDR. But from last few months I am passionate about the Digital blending. Often in the case of Night photography that we want to photograph of a scene that exceeds that of our cameras digital sensor. Your camera will give an image with either over exposed highlights or underexposed shadows. This tutorial will show you how to blend multi exposures of the same scene, one exposed for the highlights, the other exposed for the shadows. We will then use Photoshop to blend these exposures together, creating a single image containing both highlight and shadow detail .
