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.
Whether you're taking a picture of a dazzling beach sunset or documenting your weekend brunch, capturing it with HDR on can ensure that you get the best photos possible. HDR, which stands for ...
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.
HDR PhotoStudio is a discontinued high dynamic range (HDR) graphics application developed by Unified Color for the Windows and macOS operating systems. In addition to being a HDR-merge application, HDR PhotoStudio offered a set of image editing operations that worked in its dynamic range (the website showed an example of processing an image with 1,000,000:1 contrast ratio), human color range ...
Examples of computational photography include in-camera computation of digital panoramas, [6] high-dynamic-range images, and light field cameras. Light field cameras use novel optical elements to capture three dimensional scene information which can then be used to produce 3D images, enhanced depth-of-field , and selective de-focusing (or "post ...
For example, a sensor for 30fps video will give out 60fps with the odd frames at a short exposure time and the even frames at a longer exposure time. [citation needed] Modern CMOS image sensors can often capture high dynamic range images from a single exposure. [5] This reduces the need to use the multi-exposure HDR capture technique.

A higher dynamic range raw image can be reassembled and tone-mapped like usual HDR images, [4] [5] or more commonly: A blended image can be directly produced without reconstructing a higher bit-depth. [6] The former method assumes a linear response from the camera, which may be provided by DNG or other raw formats. Some variants can take ...
