High Dynamic Range Imaging, more commonly known as HDR, is a technique that involves taking multiple shots of the same image using different exposures. You then combine all the exposures so that you have an even exposure for all elements of the composition, such as sky, land and details in the shadows. In this tutorial we’ll use HDR techniques but, rather than having to shoot the subject with a tripod to get numerous exposures, we will alter the exposure on a single RAW file to get the desired result.
