Camera Technician

This is usually performed by a simple plug-in connection to the rear or side of the camera. However you should always refer to the relevant camera handbook.

A codec is file format for recording video files. Popular codecs include H.264, MJPEG, MPEG-4 AVC/H.264 and AVCHD.

A type of imaging sensor, CMOS chips are less energy consuming than CCD-type sensors and are the dominant imaging technology used in DSLRs. Although once considered an inferior technology compared to CCD sensors, CMOS sensors have vastly improved and now represent the more common sensor technology.

A bit (binary digit) is the smallest unit of digital information. Eight bits equals one byte. Digital images are often described by the number of bits used to represent each pixel, i.e., a 1-bit image is monochrome; an 8-bit image supports 256 colors or grayscales; while 24 or 32-bit images support an even greater range of color.

ATSC is the abbreviation for Advanced Television Systems Committee, which developed a set of standards for digital television transmission over terrestrial, cable, and satellite networks.

A metering mode in which the photographer sets the desired lens aperture (f-stop) and the camera in turn automatically sets the appropriate shutter speed to match the scene being recorded. Portrait photographers usually prefer wider apertures for shallower depth of field (DOF), while landscape photographers prefer smaller apertures, which bring more of the scene into sharper focus. See Shutter Priority, below.

Similar to 1080p video, the “i” stands for “interlaced,” which differs from 1080p (progressive) video in that each frame contains two fields of data (but typically has double the frame rate). While progressive video is too large for broadcast, 1080i exists primarily for broadcast use, as the lower frame rate allows the signal to be sent over 60 Hz systems. The signal is 60i for NTSC or 50i for PAL.

Creative Flair. Although being technically capable is important, creativity always needs to adapt to the project. Whereas once you know how to use a camera to a professional standard, the rate of development will lessen in comparison to thinking creatively and being innovative.

Effective Pixels is a measurement of the number of pixels that actively record the photographic image within a sensor. As an example, a camera might hold a sensor containing 10.5 megapixels, but they have an effective pixel count of 10.2 megapixels. This discrepancy is due to the fact that digital imaging sensors have to dedicate a certain percentage of available pixels to establish a black reference point. These pixels are usually arranged frame-like, along the edge of the sensor, out of range of the recorded image.

Term for lack of, or loss of, shadow detail in a photographic image, usually the result of underexposure or images captured by a lower resolution (and less dynamic) imaging sensor. Although lost shadow detail can often be (partially) reclaimed in photo-editing applications, HDR (High Dynamic Range) imaging—in which two or more bracketed images are sampled and combined into a single image file containing increased levels of shadow, highlight, and mid-tone detail—has become an increasingly common in-camera solution for retaining both shadow and highlight detail.

When setting the back focus of a Color camera for low light conditions you should place an ND1 (Neutral Density) filter in front of the lens. When setting the back focus of a Mono camera for low light conditions you should place an ND3 (Neutral Density) filter in front of the lens. When setting the back focus of a Mono camera fitted with I/R lighting for low light conditions you should place an IRP (Infra- Red Pass) filter in front of the lens.

To import digital image files into a software application for processing or editing purposes. The term is often applied differently within different types of software.

The adjustable opening—or f-stop—of a lens determines how much light passes through the lens on its way to the film plane, or nowadays, to the surface of the camera's imaging sensor. “Faster” lenses have wider apertures, which in turn allow for faster shutter speeds. The wider the aperture is set, the shallower the depth of field will be in the resulting image.

Also known as color fringing, chromatic aberration occurs when the collective color wavelengths of an image fail to focus on a common plane. The results of chromatic aberration are most noticeable around the edges of high-contrast images, especially toward the edges of the frame. Chromatic aberration is most common on less expensive lenses, although even the best optics can occasionally display lower levels of chromatic aberration, under certain conditions.

OSD (On Screen Display) cameras have a menu system within the camera assembly that can be accessed in order to set functions such as Iris levels, AGC on/off and most features of standard and advanced cameras.
