NAB Roundup 2013: LED Fresnels, Camera Accessories

P1020752

I first wrote about the development of LED Fresnel lights two years ago, tracking earlier reactions by the industry to high energy consumption and high heat output: “Greening the Film Business: LED Fresnels.” This year I followed up with some of the same manufacturers.

Fresnel lenses, originally invented for lighthouses, have long been used on movie lights for careful light control and sharp shadows. Their typical concentric ring style enables them to have great diameter without clumsy thickness. . . . CONTINUE READING: NAB Roundup 2013: LED Fresnels, Camera Accessories

Las Vegas is known for its buffets, and the NAB Show at the Vegas Convention Center is a grand smorgasbord of technology.

Camera Gallery 2012

Red Epic camera with PL lens mount and Red Volt XL battery module

It’s been quite a year for digital cinema cameras. We’ve seen new models of all sizes and form factors, from the hugest to the smallest, from still cameras that take amazing-looking video to video cameras that also shoot high-resolution stills. Here are some of the new and improved cameras of 2012. . . . CONTINUE READING: Camera Gallery 2012

NAB 2011: Greening the Film Business—LED Fresnel Lights

It’s a vicious cycle in the film business. We use scads of energy to light our sets, usually trying to make them look as natural as possible, then we use scads of energy to cool them. If we can reduce the power required for lighting, we can save money two ways. In the olden days of production, when I was starting out in the business, most movie lights (except for big arc lights) had tungsten or quartz lamps. These lamps employed a simple technology, like Edison’s light bulb, pushing so much electric current though a thin wire filament that it glowed and gave off light—and heat. Tungsten is still the most mature, least expensive, hottest, and least efficient lighting technology available. . . . CONTINUE READING: NAB 2011: Greening the Film Business—LED Fresnel Lights

NAB 2011: Digital Cinema Camera Shootout

During the recent NAB Show in Las Vegas, I attended a panel discussion and screening of a series of tests called the Single Chip Camera Evaluation. The SCCE shootout, produced by an independent, ad hoc group named Image Quality Geeks, compared 11 single-chip digital cinema cameras, along with two 35mm film emulsions. These extensive tests, designed for “apples-to-apples” comparisons, provided a comprehensive look at the following cameras.

NAB 2011: Back to Vegas

The first time I went to the NAB Show, I wore camouflage fatigues and marched through hippies.

I was working the show for Ampex, the television equipment company that had invented videotape. During the 80s, they were buying Sony professional video camera parts, assembling them in Ampex factories, and branding and marketing them as their own. One of their promotions at that time showed a photo of their new, integrated camcorders with a camouflage paint job and the caption “Guerrillacam.”

These Ampex products, based on the Sony 200 and 300 Betacam camcorders, represented a huge improvement in portability. Before this time, most professional video shooting was done either in a two-piece configuration (with camera connected to a separate recorder) . . . CONTINUE READING: NAB 2011: Back to Vegas

NAB 2011: Show Preview

The National Association of Broadcasters annual trade show takes place next week at the Las Vegas Convention Center. I’ll be there for a couple of days to check out the new cameras, among other things, and I’ll post several reports from there.

Here are some announced/rumored items I’ll be taking a close look at:

A prototype for the next (and most advanced) addition to Sony’s Cine Alta line, a new camera for digital cinematography with a sensor greater than 4K. Jon Fauer, in an article in Film and Digital Times, says the new camera will shoot from 1-72 fps in normal mode, and 1-120 fps in High Frame Rate mode.
