the various shades / tints of gray between white and black - the human eye cant see very many shades so 256 shades is enough to cover what the eye can see - which is why a gif image with 256 levels can show black and white photos perfectly but not color photos which require millions of combinations
grayscale
Grayscale refers to a range of shades of gray without distinct colors, typically representing the intensity of light in an image. In digital imaging, it signifies a mode where images are represented using varying shades from black to white, allowing for a monochromatic representation. In finance, "Grayscale" often refers to Grayscale Investments, a company that provides cryptocurrency investment products, including trusts that allow investors to gain exposure to digital currencies.
Grayscale value refers to the intensity of light in a pixel within a grayscale image, where each pixel represents a shade of gray. This value typically ranges from 0 to 255 in an 8-bit image, with 0 representing black, 255 representing white, and values in between indicating varying shades of gray. Grayscale images contain no color information, relying solely on these intensity values to convey visual information.

In Photoshop, you can view both grayscale and RGB images simultaneously by using layers and adjustment layers. You can create a grayscale layer or adjustment layer on top of an RGB image, allowing you to see the color image beneath while applying grayscale effects. Additionally, you can use the "Channels" panel to toggle between color channels and view them in grayscale. This feature is useful for comparing tonal values and color information side by side.
It is called a GrayScale. (:
Because they aren't colors, it's called "grayscale"
ctrl+shift+Uor cmd+shift+U (on mac) This makes anything inside the layer you have selected, black and white, grayscale. But there is a difference of a grayscale color mode and grayscale layer contents. Grayscale sellected from mode window, refers to the whole document. It is different than having only a layer or two in B&W and everything else in color. To switch to grayscale or any other color mode you can go to image/mode/*Grayscale (RGB, CMYK...etc)
You have to look under the drawer of a drawer in the room with the big log.
Early TV were called Black and White, (though actually they were grayscale)
