Expert Reveals The Secrets Of High-Definition Video-Image Quality In Exclusive Video

Mark Schubin, World-Renowned Video Authority, Explains the Importance of HD Camera Imager Sizes in the HDCameraGuide.com Learning Center

New York, N.Y. (PRWEB) September, 2009 -- Mark Schubin, winner of multiple Emmy awards and a fellow of the Society of Motion Picture and Television Engineers, is now sharing his world-renowned video-technology expertise with HDCameraGuide.com, the premiere online site for information about all types of HD video cameras, lenses, and accessories. In a free video at http://www.hdcameraguide.com/guide/faqs/mark-schubin-on-hd-camera-image-quality, Schubin explains the relationship between HD camera-imager size and HD video picture quality.

They all look really good...but you can't really expect something that costs $100 to provide the same quality as something that costs a quarter of a million dollars. There are many differences...one of the important differences relates to the size of the sensor, the size of the image that is formed inside the camera from which everything else derives.

"There's an extraordinary range of HD cameras out there, from little tiny ones that cost about $100, way up to digital cinematography models," Schubin says in the video's introduction. "They all look really good...but you can't really expect something that costs $100 to provide the same quality as something that costs a quarter of a million dollars. There are many differences...one of the important differences relates to the size of the sensor, the size of the image that is formed inside the camera from which everything else derives."

Schubin then proceeds to elaborate on this point and to explain how related factors such as sensitivity, signal-to-noise ratio, HD dynamic range, depth of field, wide-angle lenses, zoom ratios, and optical aberrations all play a role in determining HD camera image quality. "All things being equal," Schubin concludes, "the larger the video-imager format, the better the video is going to look."

Experts at HDCameraGuide.com concur, noting that although HD cameras with 1/3-inch (and even smaller) imagers are proliferating among consumers, prosumers, and even some professional users, HD cameras with 2/3-inch and larger CCD and CMOS camera-imagers continue to dominate in such premium-quality production sectors as televised sports, documentaries, network program production, and digital cinematography.

Since its launch less than a year ago, HDCameraGuide.com has become the premier HD camera information site for all levels of interest. In addition to its extensive information on HD cameras, lenses, and accessories for broadcast, professional, and digital cinematography, HDCameraGuide.com also features a consumer section with extensive data and informative videos on all major prosumer and consumer brands of HD camcorders and digital photography cameras.
