In photography, shutter speed or exposure time is the length of time that the film or digital sensor inside the camera is exposed to light (that is, when the camera's shutter is open) when taking a photograph. [1] The amount of light that reaches the film or image sensor is proportional to the exposure time.
Example of a low-key photograph. Low-key photography is a genre of photography consisting of shooting dark-colored scenes by lowering or dimming the "key" or front light illuminating the scene (low-key lighting), and emphasizing natural [1] or artificial light [2] only on specific areas in the frame.

HDSLRs can achieve much shallower depth of field and superior low-light performance. However, the low ratio of active pixels (to total pixels) is more susceptible to aliasing artifacts (such as moiré patterns) in scenes with particular textures, and CMOS rolling shutter tends to be more severe. Furthermore, due to the DSLR's optical ...
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 advantage of independence from a light meter, the sunny 16 rule can also aid in achieving correct exposure of difficult subjects.
Features of the F60 include the 'T' Time setting - where a first press of the shutter release opens the shutter, and a second closes it, and AF servo tracking in 'Sport' mode. The camera also supports five different flash modes, including 'slow' for low light scenes. The film speed is only automatically adjustable by DX encoding.
On a number of cameras this is the default or standard setting. The camera measures the light intensity in several points in the scene and then combines the results to find the setting for the best exposure. The method of calculation can be different from camera to camera. The actual number of zones used varies widely, from several to over a ...
Low key light accentuates the contours of the subject by throwing areas into shade while a fill light or reflector may illuminate the shadow areas to control contrast. [2] [1] The relative strength of key-to-fill, known as the lighting ratio, can be measured using a light meter. Low key lighting has a higher lighting ratio, e.g., 8:1, than high ...
When the shutter is released, the mirror moves out of the light path, and the light shines directly onto the film (or in the case of a DSLR, the CCD or CMOS imaging sensor). Exceptions to the moving mirror system include the Canon Pellix and Sony SLT cameras , along with several special-purpose high-speed cameras (such as the Canon EOS-1N RS ...
