Wibbly Wobbly Waveforms
N/A The very first analytical electronic instrument, developed in the late 1890s, was the oscilloscope. This used a cathode ray tube (CRT) to paint a graph of voltage on the Y axis versus time on the X axis. Once television became a practical reality in the 1930s, the same instrument was applied to the video output from the camera and became the very useful waveform monitor.

Watch out for dead pixels
N/A A dead pixel in a camera imaging sensor can manifest itself in a number of ways. Implying black, 'dead' is not necessarily the correct term for a pixel failure. This is because imager defects include hot pixels, sparkles, noisy or lazy pixels. These problems usually arise during the chip manufacturing process.

Light weight 3D side-by-side production
N/A Whenever you see a typical publicity picture of a 3D production shoot, it invariably includes a very bulky and expensive-looking mirror rig. This can look daunting for the new initiate coming into 3D production and is not the sort of kit you might not want to risk using outdoors.

Headache-free 3D
N/A Whatever display technology is used to deliver the 3D images, it is obviously important not to send viewers home with a headache, particularly before they have actually invested in a 3D system of their own. It helps a lot if 3D programme producers understand what causes such headaches because only then can they take effective measures to avoid them.

Getting close to the edge?
N/A 'Edge Violation A visual artifact that can arise when part of an object near the edge of the display is represented in the left-eye image but is not represented in the right-eye image or vice versa.' So says the 3D glossary given by 3D@Home.

Eyeballing 3D errors
N/A Standard-issue human eyeballs are very adaptive and clever. Of course its the massively powerful image processing in the visual cortex of the brain that really allows us to resolve 3D images.
