sensor
Variations command

No change. The EXPOSURE doesn't change or it would also change the background as well. Move the lights to adjust.

28. An in-camera reflected meter reading a very dark scene indicates an exposure of 1/250th at f/8. For a correct exposure - what should you do?
dynamic range (not to be confused with gamut)
On a scanner; it guesses what the pixels look like in between the ones the scanner can actually measure.
Parallax
Use negative exposure compensation (underexpose). The meter will attempt to make the dark scene 18% grey - underexpose to bring it back to dark.

29. How does 'unsharp mask' work?
Yellow
Change the shutter speed. The longer the shutter speed - the lighter the background will be. The faster the shutter speed - the darker the background will be because less existing light is captured.
The intensity of the illumination is inversely proportional to the square of the distance from light to subject. At twice the distance from the subject - the light illuminates only 1/4 of the original.
It emphasizes the edges between tones. A threshold of zero affects all pixels - a higher threshold affects just the edges with high tonal difference and minimizes noise.

30. What is the inverse square law?
hue/saturation adjustment layer
The intensity of the illumination is inversely proportional to the square of the distance from light to subject. At twice the distance from the subject - the light illuminates only 1/4 of the original.
