iSight is a brand name used by Apple Inc. to refer to webcams on various devices. The name was originally used for the external iSight webcam, which retailed for US$149, connected to a computer via a FireWire cable, and came with a set of mounts to place it atop any then current Apple display, laptop computer, all-in-one desktop computer, or round surface.
The M42 lens mount is a screw thread mounting standard for attaching lenses to 35 mm cameras, primarily single-lens reflex models. It is more accurately known as the M42 × 1 mm standard, which means that it is a metric screw thread of 42 mm diameter and 1 mm thread pitch.
The Sony Mavica (a magnetic still video camera) used a color-striped 2/3” format CCD sensor with 280K pixels, along with analog video signal processing and recording. [6] The Mavica electronic still camera employed a TTL single-lens reflex viewfinder, as shown in the graphic from a June 1982 Sony press release.
This list compares main features of digital single-lens reflex cameras (DSLRs). Order of this list should be firstly by manufacturer alphabetically, secondly from high end to low end models. Brand
A three-CCD (3CCD) camera is a camera whose imaging system uses three separate charge-coupled devices (CCDs), each one receiving filtered red, green, or blue color ranges. Light coming in from the lens is split by a beam-splitter prism into three beams, which are then filtered to produce colored light in three color ranges or "bands".
Red dot sights are considered to be fast-acquisition and easy-to-use gun sights for firearms used in civilian target shooting, hunting, or in police and military applications. They are also used on cameras and telescopes. On cameras they are used to photograph flying aircraft, birds in flight, and other distant, rapidly moving subjects.
These allow high-quality 21st century telescopic sights to practically achieve measured over 90% light transmission values in low light conditions. [17] Depending on the coating, the character of the image seen in the telescopic sight under normal daylight can either "warmer" or "colder" and appear either with higher or lower contrast.
The base mount is the connection between the tripod head and the tripod legs. Often the head will have a fairly large, flat base that sits on top of the tripod, and uses cork or rubber to increase the friction between the two, to prevent the head from unscrewing during use. The actual connection between the two is often made with a screw.
