Use 'grayscale' when referring to images or displays that are in black and white or use varying shades of gray.

Examples:

The photograph was converted to grayscale for a vintage effect.
The printer can only print in grayscale.

Alternatives:

black and white
monochrome
shades of gray
black and gray

Use 'gray value' when discussing the specific intensity or value of a shade of gray, especially in technical or analytical contexts.

Examples:

The gray value of the pixel was measured using specialized software.
The image processing algorithm calculates the gray values of different regions.

Alternatives:

gray level
intensity of gray
shade of gray intensity
gray scale

Both 'grayscale' and 'gray value' are correct, but they are used in different contexts. 'Grayscale' is commonly used to refer to an image or display that uses varying shades of gray, while 'gray value' is more often used in technical contexts to describe the intensity of a specific shade of gray.
