Depending on the manufacturer, the increased light from these sources can be used either to improve the image's brightness or to create a more uniform light level across the screen, eliminating the "hot spot" that forces viewers of rear-projection TVs to sit at a particular height to see the best picture.
Using a virtual replica of the actual installation, the sound analysis software modifies the behavior and properties of each tungsten bulb including speed, brightness, and intensity to create a visually stunning light show.
We then used the luminance database to create standard and 'articulated' brightness contrast stimuli.
Before the launch of X-ray-observing satellites, such as the Chandra X-ray Observatory, X-ray observations generally had quite low angular resolution, but when the Moon passes in front of the nebula, its position is very accurately known, and so the variations in the nebula's brightness can be used to create maps of X-ray emission.
Though light colors such as whites, cream colors, and icy blues are effective colors to create brightness, they need to be contrasted against darker colors such as darker beige, blue, or gray in order to really stand out.
The solution, Mr. Kohn said, is to create "lightness, brightness and cheerfulness" by replacing the stubby brown columns along the arcade with stainless-steel cylinders; substituting light gray granite paving for the dark brown brick; and installing a screen of translucent and clear glass panels, illuminated from behind, along the parapet of the 57th Street arcade.
Computer processing of many such observations can be used to create a brightness map.
I asked if we could use the Surface 2.0's ability to see things before they touched the screen and "magically" make the handle appear, but there wasn't enough time to create the brightness-based blob creation I had in mind.
In addition, monitoring the changes in the total brightness of the two bodies as they blocked each other permitted astronomers to estimate their individual overall albedos and even to create maps depicting brightness differences over their surfaces.
Designed to convert standard dynamic range content into something that approximates to HDR, on the OLED65W7 the mode opts to reduce the average brightness of the SDR signal - presumably to create enough dynamic range to deliver HDR peaks.
