November 30, 2009 – Throughout its history, broadcast video production has been driven by advances in technology, from black & white kinescopes to “living color” videotape, from instant replay to digital television, from the HD of today to perhaps the 3D HD of tomorrow.

And throughout all these advances, one thing has remained constant: The need to be better.

In a Special Report, exclusively on HD Camera Guide (http://www.HDCameraGuide.com), Dave Bancroft, Industry Consultant, and Mark Schubin, Technology Consultant gives their insights into when to consider 2/3-inch imagers. Mr. Bancroft’s comments appear in a White Paper, while Mr. Schubin’s appear in a video interview.

In part, Mr. Bancroft writes, “The loss of natural image sharpness is not the only disadvantage of a very small format camera sensor; for the same number of pixels, e.g. 1920 x 1080, each pixel in the sensors will be smaller, which means it collects less light and produces fewer electrons to make the output signal. That means worse sensitivity and worse signal to noise ratio. A further small format disadvantage is that the range of lens taking angles that are needed, especially for studio work, is limited. It is particularly difficult to get wide-angle lenses, because a much shorter focal length is needed for the same taking angle as the larger format.

“Overall, the “sweet spot” for broadcasters in HDTV is still the 2/3-inch optical format size, because together with a convenient range of lens angles and good sensitivity it allows a useful range of lens iris settings between the two optical limits of diffraction limiting at small apertures and lens aberrations at large apertures….”

These important tutorials can help broadcasters and program producers make a more informed decision when choosing an HD camera.

Also featured on HD Camera Guide’s Learning Center are interactive videos, which allow the view to “Ask This Speaker A Question.”

You can ask Larry Thorpe of Canon’s Broadcast Division about comments he’s made in his Learning Center video on “The Importance of Quality Camera Optics.”

You can also ask experts about “Shooting in High Definition,” “HD Camera Technology,” and more. You can even ask about “Choosing a Teleprompter,” especially if you plan to run for higher office.

“Interacting with our exclusive Learning Center videos is one more advantage we offer at HD Camera Guide,” states editor Michael Grotticelli. “It’s not a real-time podcast, which means you don’t have to sit at your computer during the presentation. You can watch anytime and email your question for the speaker’s response.”

Visitors can also register for Learning Center video updates free and easy.

Since its launch less than a year ago, HD Camera Guide has become the fastest growing online guide to broadcast/professional and consumer cameras.

The site is video-rich including educational as well as product vides from companies that include Sony, Canon, Panasonic, Ikegami, Grass Valley, and many more.

Plus there are three Interactive Selector Guides.

The unique interactive Teleprompter Selector featured only on HD Camera Guide www.HDCameraGuide.com actually lets visitors select their camera brand and model, type of lens, pan/tilt head brand and series, and receive first and second choice teleprompter model recommendations. The user can then find out more, by clicking on either recommendation for complete details.

The Teleprompter Selector features Teleprompters from Autoscript, the industry leader, and was the brain-child of Autoscript Vice President Gordon Tubbs. “There’s more than meets the eye when it comes to choosing the right Teleprompter for your camera/lens set-up, stated Tubbs in a recent interview. “While we’re pleased that Autoscript is the industry leader, it’s equally important that our customers get the right teleprompter that meets their equipment requirements. That’s why we worked with HD Cameras Guide to create this in-depth interactive tool.

HD Camera Guide also features an interactive Camera Selector, and HD Lens Selector featuring Canon lenses. With the camera selector, visitors can choose by brand or application, while the lens selector lets visitors chose the right lens for their camera brand, model, and specific application.

The site which continues to generate page 1 results on the search engines for a wide range of industry specific keywords including “hd camera”, “best HD camera” and many others brand/model-specific searches, also lets viewers visit manufacturer websites without leaving HD Camera Guide.
