question 17
5 pts
how different components of a color are combined or subtracted to create color. examples: rgb, cmyk, grayscale.

Explanation:

For Question 16, photography exposure depends on aperture, shutter - speed, and ISO. For Question 17, color models define color creation methods.

Answer:

Question 16: The amount of light used when taking a photograph is determined by factors such as aperture (controls the size of the lens opening), shutter - speed (controls the time the sensor is exposed to light), and ISO (sensor sensitivity to light).
Question 17: Color models like RGB (additive color model where red, green, and blue light are combined to create different colors), CMYK (subtractive color model used in printing where cyan, magenta, yellow, and key/black are combined), and Grayscale (uses different levels of gray to represent an image without color) describe how different components of a color are combined or subtracted to create color.
