The Nikon D4S's processor is identical to the Nikon D4, marked EI-158, using its processing power with improved software enabling 1080p video capture at 50/60fps, 11 fps photos with improved autofocus, new noise reduction with image-content variable algorithm (context-adaptive) [44] [45] and other improvements.

Every time lenses are changed, dust may enter the camera body and settle on the image sensor. Digital single-lens reflex cameras (DSLR) are particularly vulnerable to this issue, since the interior of the camera is exposed during lens changes unlike other forms of digital cameras, and the image sensor is fixed, unlike a film camera. Even the ...
The Nikon D3100 is a 14.2-megapixel DX format DSLR Nikon F-mount camera announced by Nikon on August 19, 2010. It replaced the D3000 as Nikon's entry level DSLR. It introduced Nikon's new EXPEED 2 image processor and was the first Nikon DSLR featuring full high-definition video recording with full-time autofocus and H.264 compression, instead of Motion JPEG compression.
The free software Canon Hack Development Kit (CHDK) project, started by Andrey Gratchev, has successfully enhanced many Canon PowerShot cameras without replacing the stock firmware. [ 29 ] [ 30 ] It allows programmatic control of many Canon compact cameras, enabling users to add features, including games and scripts written in UBASIC or Lua .
The high sensitivity image quality of a given camera (or RAW development workflow) may depend greatly on the quality of the algorithm used for noise reduction. Since noise levels increase as ISO sensitivity is increased, most camera manufacturers increase the noise reduction aggressiveness automatically at higher sensitivities. This leads to a ...
A sound blimp is a housing attached to a camera which reduces sounds, such as shutter click on SLR cameras, and motors on motion picture cameras. It is primarily used in film still photography, so as not to interfere with the shooting of principal photography [dubious – discuss], and also in other situations where sound is distracting: theatrical photography, surveillance, and wildlife ...
Image stabilization (IS) is a family of techniques that reduce blurring associated with the motion of a camera or other imaging device during exposure.. Generally, it compensates for pan and tilt (angular movement, equivalent to yaw and pitch) of the imaging device, though electronic image stabilization can also compensate for rotation about the optical axis ().

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]
