The Sony Cyber-shot DSC-HX400V is a hyperzoom bridge digital camera that features: 20.4-megapixel Exmor CMOS sensor; Fast f/2.8 Carl Zeiss Vario-Sonnar T* 50× optical zoom lens; Optical SteadyShot and Optical SteadyShot Intelligent Active Mode lens-based stabilisation to reduce blurring from shaky hands; 100× digital zoom
The ISO arithmetic speed has a useful property for photographers without the equipment for taking a metered light reading. Correct exposure will usually be achieved for a frontlighted scene in bright sun if the aperture of the lens is set to f/16 and the shutter speed is the reciprocal of the ISO film speed (e.g. 1/100 second for 100 ISO film).
In many instances, this was done: the 1973 and 1986 ANSI exposure guides, ANSI PH2.7-1973 and ANSI PH2.7-1986, eliminated exposure calculator dials in favor of tabulated APEX values. However, the logarithmic markings for aperture and shutter speed required to set the computed exposure were never incorporated in consumer cameras.
The Sony Cyber-shot DSC-QX100 is a mobile device-mountable lens-style compact camera manufactured by Sony. Announced on September 3, 2014, the QX100 is one of Sony's " Smart Lens " cameras, alongside the QX1 , QX10 and QX30 , that are specifically designed to be used with a smartphone.
Performing this calculation mentally is tedious for most photographers, but the equation is easily solved with a calculator dial on an exposure meter (Ray 2000, 318) or a similar dial on a standalone calculator. If the camera controls have detents, constant exposure can be maintained by counting the steps as one control is adjusted and counting ...
An example of the use of f-numbers in photography is the sunny 16 rule: an approximately correct exposure will be obtained on a sunny day by using an aperture of f /16 and the shutter speed closest to the reciprocal of the ISO speed of the film; for example, using ISO 200 film, an aperture of f /16 and a shutter speed of 1 ⁄ 200 second. The f ...
In photography, reciprocity refers to the relationship whereby the total light energy – proportional to the total exposure, the product of the light intensity and exposure time, controlled by aperture and shutter speed, respectively – determines the effect of the light on the film. That is, an increase of brightness by a certain factor is ...
