High dynamic range (HDR), also known as wide dynamic range, extended dynamic range, or expanded dynamic range, is a signal with a higher dynamic range than usual. The term is often used in discussing the dynamic ranges of images , videos , audio or radio .
Tone mapped high-dynamic-range (HDR) image of St. Kentigerns Roman Catholic Church in Blackpool, Lancashire, England, UK. Tone mapping is a technique used in image processing and computer graphics to map one set of colors to another to approximate the appearance of high-dynamic-range (HDR) images in a medium that has a more limited dynamic range.
High dynamic range. Techniques that allow a digital image to show a wider contrast range than current image sensors can record in one file. Some cameras have firmware to do the processing. [10] ICM: Intentional camera movement. The camera or the focus or zoom of its lens is adjusted by the photographer during an exposure in order to achieve ...
Compressing this high dynamic range into a print either requires uniformly decreasing contrast (making tones closer together) or carefully printing different parts of an image differently so that each retains the maximum contrast – in this latter dodging and burning is a key tool.
When attempting a single-exposure of a high dynamic-range scene, a reduction in exposure from the meter's reading may be needed. [ dubious – discuss ] In the final analysis, however, the camera's meter is irrelevant to ETTR since the ETTR exposure is established, not by a meter reading, but by the camera's exposure indicators, the histogram ...
High-dynamic-range imaging (HDR) addresses this problem by increasing the dynamic range of images by either increasing the dynamic range of the image sensor, or; using exposure bracketing and post-processing the separate images to create a single image with a higher dynamic range.

Tone mapped high-dynamic-range (HDR) image of St. Kentigern's Church in Blackpool, Lancashire, England. In photography and videography, multi-exposure HDR capture is a technique that creates high dynamic range (HDR) images (or extended dynamic range images) by taking and combining multiple exposures of the same subject matter at different exposures.
