Crossing The Line

HD-SDI cable, and the 180° rule explained

The Right 8 Bits

What’s two bits between friends?

For DSLR shooters, the cool current "must-have" feature is Clean HDMI.

At AbelCine, we’ve embraced the trend toward external video recorders. Convergent Design’s nanoFlash, launched in 2009, was one of the first on-camera HD recorders that actually offered improved recording quality over what was found in the camera.

All By Myself

A unique USB microphone, and devising a preproduction sound checklist

Get The Balance Right

Tiffen’s Dfx software, dealing with compression and off the beaten path at NAB

ACHIEVING THE RIGHT BALANCE Q I don’t always get the white balance right when I’m shooting. Sometimes when I’m running and gunning, I’m not looking at a good color image on a monitor.

Disruptive Tech v2.0

With lower margins, the 99% wins

Many years ago, when I first started attending trade shows like NAB and Cine Gear, you always could count on seeing impressive booths from industry-standard companies like Panavision, Kodak and Apple, as well as pro rental houses displaying massive dollies and cranes.

Lost In Transfer

It’s all in the details

FILE TRANSFERS Q I ran into a situation recently that has me a bit worried. I was shooting double-system sound, which I’ve done many, many times.

Reality Is Relative

How Rango’s photo-realism is changing the future of movies

Misinformation isn’t always unintentional. As Martin Scorsese’s Hugo made lovingly clear, filmmakers have always been magicians and illusionists, expertly blurring the line between reality and fantasy.
