Even the most advanced digital cameras have a limited dynamic range. With drastic lighting contrasts, this limitation is easy to see, for example, in a photo taken indoors and facing outdoors, as in the first example shot. You either have a well-lit interior where the surrounding park behind the archways is far too bright, or an image with an adequately lit park where the interior is far too dark.

HDR technology, short for High Dynamic Range, solves this problem by creating images with an extremely wide dynamic range that cannot be matched by monitor displays or prints.

The idea is simple: multiple images with different exposure times are merged into one image. In our example, three shots are merged: one with a longer exposure time to capture the dark details inside the pavilion, one with a short exposure time to properly illuminate the park behind the pavilion, and one shot right in the middle.

The combined result is a single image that contains all the details of light, midtones and shadows. HDR projects 7 professional does this work for you. The powerful program merges the exposure series and creates a print- and screen-ready photo using Tone Mapping.

The combined image contains all the details of the pavilion and the park, lit exactly as we saw the scene with our own eyes.

An obvious case for professional HDR projects - an evening scene with lanterns can only be captured naturally with HDR technology. Otherwise, the dark environment with bright lights would be impossible to capture. The contrast range of a camera sensor is very limited compared to that of the human eye.
