Answer 2

Pixel value (dn) depends on greyscale colour of the object brightness/emissivity of the object wavelength of the radiation

What is Pixel value?

• Each pixel that makes up a picture that is stored on a computer has a pixel value that specifies its brightness and/or intended colour.
• The pixel value in binary images is often a 1-bit number that denotes either the foreground or the background. The pixel value for a grayscale image is a single number that denotes the brightness of the pixel.
• The byte image, which stores this number as an 8-bit integer with a possible range of values from 0 to 255, is the most popular pixel format. Normally, 255 is considered to be white while zero is considered to be black.
• The many colours of grey are made up of values in between.
