The future or something that happened to them
The amount of light that passes through the lens and reaches the digital sensor is called exposure.
So, exposure determines how much light or darkness will get to the sensor, and thus how light or dark the image will be when you take a photo. There are settings that are responsible for this: ISO, aperture, and shutter speed - which together are called "the exposure triangle."
As an adhesive for two materials that aren't too smooth.
I believe the answer is Monochromatic
A color scheme could be categorized as monochromatic if it's derives only from single based hue using additional tints, tones, and shades.
The usage of these will alter the brightness and the saturation of the color just like what we see in the painting.
