For example, in portrait mode, the camera would use a wider aperture to render the background out of focus and would seek out and focus on a human face rather than other image content. In the same light conditions, a smaller aperture would be used for a landscape, and recognition of faces would not be enabled for focusing.
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.
Through the lens metering measures the luminance after it has passed through the camera lens, thus providing readings or settings that allow for aperture and focus changes, filters, etc. [11] UV: Ultraviolet. The electromagnetic radiation with wavelengths shorter than about 400 nm and not visible to the human eye. [19] WB: White balance.
In photography, the metering mode refers to the way in which a camera determines exposure. Cameras generally allow the user to select between spot, center-weighted average, or multi-zone metering modes. The different metering modes allow the user to select the most appropriate one for use in a variety of lighting conditions.
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. Apart from the ...
Zoom burst, a photograph taken with a zoom lens, whose focal length was varied during the course of the exposure. In a sense, ICM is the same effect as (intentional) single-exposition motion blur: in the former the camera moves during exposure, in the second the target moves, but they have in common that there is relative motion between camera and target, often resulting in streaking in the image.
A Nikon-style mode dial showing aperture priority mode.. Aperture priority, often abbreviated A or Av (for aperture value) on a camera mode dial, is a mode on some cameras that allows the user to set a specific aperture value while the camera selects a shutter speed to match it that will result in proper exposure based on the lighting conditions as measured by the camera's light meter.
Vignetting is a common feature of photographs produced by toy cameras such as this shot taken with a Holga. This example shows both vignetting and restricted field of view (FOV). Here a "point-and-shoot camera" is used together with a microscope to create this image. Pronounced vignetting (fall off in brightness towards the edge) is visible as ...
