HDR: Part 4 - Surviving Modern Colorimetry June 29th 2022 - 09:55 AM

Most people are aware that any color can be mixed from red, green and blue light, and we make color pictures out of red, green and blue images. The relationship between modern color imaging and the human visual system was recently discussed by John Watkinson in his series on color. In this piece, we’re going to look at something that comes up often in modern film and TV technique: color gamuts. It’s a term that suffers a lot of misuse, but the basics are simple: a color image uses red, green and blue, and the gamut describes which red, which green, and which blue we’re using.

HDR: Part 3 - Grading June 16th 2022 - 09:30 AM

Almost since photography has existed, people have pursued ways of modifying the picture after it’s been shot. The “dodge” and “burn” tools in Photoshop are widely understood as ways to make things brighter or darker, but it’s probably less widely understood that they refer to techniques for exposure control that date all the way back to the earliest days of darkroom image processing. Bring moving images into the mix and consistency becomes a big concern too. Individual still photographs might be part of a single exhibition, but they don’t have any concept of being cut together in a sequence.

Information: Part 3 - Applying Statistics June 6th 2022 - 09:00 AM

We are not done with statistics yet. In a sense we will never be done with it and it is better to know how to deal with it than to ignore it. It is better still to know how others commonly fail to deal with it and reach conclusions that cannot be justified. It is typically very hard to explain to people who do not understand.

HDR: Part 2 - Brightness Encoding May 27th 2022 - 01:00 PM

Dealing with brightness in camera systems sounds simple. Increase the light going into the lens; increase the signal level coming out of the camera, and in turn increase the amount of light coming out of the display. In reality, it’s always been more complicated than that. Camera, display and postproduction technologies have been chasing each other for most of the last century, especially since a period in the late 1990s or early 2000s, when electronic cameras started to become good enough for serious single-camera drama work.
