In the center, the image captures a bit of detail in the clouds and some in the trees. The composite above is of three separate images I took with different exposures of the same scene. Lightroom Fanatic – Composite Of Three Exposure Images To demonstrate, I took these images on a trip up to the mountains. Tone mapping is so synonymous with HDR that the terms are often used interchangeably, but HDR is a general term for the idea of capturing a wide range of contrast, and tone mapping is a technique for processing HDR images in to something practical. One of the things you can do with HDR involves taking multiple images with different exposures to capture those details in both the lights and the darks. The specific technique photographers use to create an image that squishes these multiple exposures in to an image that can “fit” in to the functional dynamic range for viewing or printing is called tone mapping. You, as the photographer, choose which is more important and set your exposure accordingly, losing detail in either the shadows or the highlights as a result. If the scene you are trying to take a picture of has some really dark areas and some really bright areas, your camera may not be able to capture detail from both areas in one image. When you take a photograph, your camera is capable of capturing a certain range of light, just like your eye is able to observe a certain range of contrast within a scene. High Dynamic Range (HDR) is a technique used in photography to capture a greater dynamic range between the lightest and darkest areas of an image.
