Exposure is further controlled in each of the above modes with an independent setting for: Ev: Exposure value enables an increase/decrease in image exposure compensation to make the resulting image brighter/darker, typically selectable in steps of whole or partial exposure "stops" (discrete widening/tightening of the aperture). Many cameras ...
High-dynamic-range rendering (HDRR) is the real-time rendering and display of virtual environments using a dynamic range of 65,535:1 or higher (used in computer, gaming, and entertainment technology). [6] HDRR does not require a HDR display and originally used tone mapping to display the rendering on a standard dynamic range display.
Electronic camera specifications [ edit ] In electronic camera specifications frame rate refers to the maximum possible rate frames that can be captured (e.g. if the exposure time were set to near-zero), but in practice, other settings (such as exposure time) may reduce the actual frequency to a lower number than the frame rate.
Sunlit subject shot on a digital camera set to ISO 100, exposed at f/8 at 1/400 second which is the same exposure value as f/16 for 1/100 second, the recommended "sunny 16" exposure In photography, the sunny 16 rule (also known as the sunny f /16 rule ) is a method of estimating correct daylight exposures without a light meter .
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.
An example of bloom in a picture taken with a camera. Note the blue fringe that is particularly noticeable along the right edge of the window. Bloom (sometimes referred to as light bloom or glow ) is a computer graphics effect used in video games , demos , and high-dynamic-range rendering (HDRR) to reproduce an imaging artifact of real-world ...
Exposure is a combination of the length of time and the illuminance at the photosensitive material. Exposure time is controlled in a camera by shutter speed, and the illuminance depends on the lens aperture and the scene luminance. Slower shutter speeds (exposing the medium for a longer period of time), greater lens apertures (admitting more ...
Exposure compensation is a technique for adjusting the exposure indicated by a photographic exposure meter, in consideration of factors that may cause the indicated exposure to result in a less-than-optimal image. Factors considered may include unusual lighting distribution, variations within a camera system, filters, non-standard processing ...
