Apply Greyscale

Greyscale transformation allows users to convert a color image into a black-and-white image where the shades of gray are used to represent different levels of brightness in the original image.

Convert to 8-bit greyscale; 256 shades of grey. This is a linear operation. If the input image is in a non-linear color space such as sRGB, use gamma with greyscale for the best results. By default, the output image will be web-friendly sRGB and contain three (identical) color channels.
