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.
Likewise, with digital cameras, images taken at higher sensitivity settings show more image noise than those taken at lower sensitivities. [ 6 ] However, even if both techniques have inherent noise, it is widely appreciated that for color, digital photography has much less noise/grain than film at equivalent sensitivity, leading to an edge in ...
Computational photography can improve the capabilities of a camera, or introduce features that were not possible at all with film-based photography, or reduce the cost or size of camera elements. Examples of computational photography include in-camera computation of digital panoramas, [6] high-dynamic-range images, and light field cameras.
Photo interpretation at the U.S. National Photographic Interpretation Center during the Cuban Missile Crisis.. Aerial photographic and satellite image interpretation, or just image interpretation when in context, is the act of examining photographic images, particularly airborne and spaceborne, to identify objects and judging their significance.

An example is Microsoft's Photosynth, which provided some models of famous places as examples. [54] Panoramic photographs can be created directly in camera without the need for any external processing. Some cameras feature a 3D Panorama capability, combining shots taken with a single lens from different angles to create a sense of depth.
The 1964 ASA standard for automatic exposure controls for cameras, ASA PH2.15-1964, took the same approach, and also used the more descriptive term camera exposure settings. Common practice among photographers is nonetheless to use "exposure" to refer to camera settings as well as to photometric exposure.
Macro settings on digital cameras tend to do this automatically, as they have a narrow depth of field to begin with; the same effect can be achieved with manual adjustment. A photograph showing simplicity should have a clear reason the subject was chosen. The reason for taking the picture should be clearly evident.
For example, as of 2008, Nikon cameras allow one to set the maximum and minimum ISO sensitivities, and slowest shutter speed that will be used in automatic modes, [4] while Canon cameras will select within the fixed range of ISO 400–ISO 800 in Auto ISO mode. In Nikon cameras, the Auto ISO mode first adjusts the shutter speed, keeping ISO at ...
