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]
Canon printers are supplied with Canon Advanced Printing Technology (CAPT), a printer driver software stack developed by Canon. The company claims that its use of data compression reduces their printer's memory requirement, good quality compared to conventional laser printers, and also claim that it increases the data transfer rate when ...
Shutter lag is much more of a problem with digital cameras.Here, the delay results from the charging of the charge-coupled device (CCD) image sensor and relatively slow transmission of its capture data to the circuitry of the camera for processing and storage.
Such RAW codecs are currently available from Canon, Nikon, Olympus, Pentax, Sony and for Adobe DNG. Many applications on Mac OS X use either the Core Image or QuickTime APIs for image support. This enables reading and writing to a variety of formats, including JPEG , JPEG 2000 , Apple Icon Image format , TIFF , PNG , PDF , BMP and more.
Focal-plane shutters may also produce image distortion of very fast-moving objects or when panned rapidly, as described in the Rolling shutter article. A large relative difference between a slow wipe speed and a narrow curtain slit results in distortion because one side of the frame is exposed at a noticeably later instant than the other and the object's interim movement is imaged.
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 new Canon EOS-1D Mark II N features the same 8.2 megapixel CMOS sensor, DIGIC II image processor and 8.5 frame per second shooting speed of its predecessor. The primary changes are a new 2.5" wide viewing angle LCD monitor, Evaluative Metering, an improved buffer, and new 'Picture Style' image parameters.
The Booster [54] accessory for the Canon Pellix QL (1965) and Canon FT QL (1966) supported film speeds from 25 to 12800 ASA. The film speed dial of the Canon A-1 (1978) supported a speed range from 6 to 12800 ASA (but already called ISO film speeds in the manual). [55] On this camera exposure compensation and extreme film speeds were mutually ...
