Plato's cavemen looked into an illusory fire, with the sun behind them; we watch brightness projected on to a screen, whose purpose is to conceal reality not reveal it.
By projecting the simulated quantities along the axes of the computational domain, we produce maps of X-ray surface brightness, temperature, projected mass density, and simulated X-ray observations.
The Smartbeam® High-Intensity Discharge (HID) headlamps -- standard on the RT trim package project light and attitude with equal authority, instantly adjusting brightness and intensity when headlights from an approaching vehicle are detected.
I stared at the halo of metallic brightness across the street, projecting into the pedestrian sphere.

More sophisticated exposure control systems measure either the brightness of selected image portions projected on the enlarger baseboard or the average light intensity reaching the paper during the exposure.
A miniature optical engine with LED light source has the advantages of good power consumption, useable projected image, reasonable brightness and uniformity, compactness in volumetric size and decent performance specifically for high spatial frequencies.
The HUD automatically adjusts brightness levels to ensure that projected information is easy to read during the day and at night.
In Figure 11, the background brightness varies little when shadow projects on the background, meanwhile the background is complex and close to the foreground color.
The images obtained in this way are fully transparent (Fig. 8c), but can be used to project reflection with enhanced brightness, for example on a wall or on a screen (Fig. 8g i).
