Magic Lantern is a firmware add-on for various Canon digital single-lens reflex (DSLR) cameras and the EOS M. [2] It adds features for DSLR filmmaking and still photography, and is free and open-source. Magic Lantern was originally written for the Canon EOS 5D Mark II [3] by Trammell Hudson in 2009 after he reverse engineered its firmware. [1]
On a sunny day and with ISO 100 film / setting in the camera, one sets the aperture to f /16 and the shutter speed (i.e. exposure time) to 1 / 100 or 1 / 125 [2] seconds (on some cameras 1 / 125 second is the available setting nearest to 1 / 100 second).
Detail of front of Kodak Retina Ib 35mm camera (c. 1954) showing the EV setting ring that couples aperture and shutter speed settings A Kodak Pony II camera (1957–1962) with exposure value setting ring. This camera has a fixed shutter speed, so the "EXP VALUE" ring simply sets the aperture. On most cameras, there is no direct way to transfer ...
Shutter priority refers to a shooting mode used in cameras. It allows the photographer to choose a shutter speed setting and allow the camera to decide the correct aperture. This is sometimes referred to as Shutter Speed Priority Auto Exposure, or TV (time value on Canon cameras) mode, S mode on Nikons and most other brands. [citation needed]
The No. 11 was intended for leaf shutter-type cameras and M sync photoflash triggering, which gave M bulbs a head start by delaying the opening of the shutter so any given camera's fastest exposure time would be centered at the 20 ms point (an 18.75 ms delay for instance, for a definitional camera capable of 1 / 400 th second exposures, or 2.5 ms).
Canon, Pentax and Leica cameras use 'Av' and 'Tv' to indicate relative aperture and shutter speed as well as to symbolize aperture priority and shutter priority modes. Some Pentax DSLRs even provide a 'TAv' exposure mode to automatically set the ISO speed depending on the desired aperture and shutter settings, and 'Sv' (for sensitivity priority ...
DEP: [3] DEP (DEPth of field) mode, on some Canon cameras, set the aperture to yield the desired depth of field: one point at the nearest object that one wants to be in focus, half-presses the shutter, then points at the farthest object that one wants to be in focus, half-presses the shutter, at which point the camera sets both focus and ...
Digital cameras usually have variable ISO settings that provide additional flexibility. 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 ...
