There are a few ways to remove color from Photoshop. The first way is to use the “Color Remove” tool. This tool removes all colors from a image, leaving only black and white. The second way is to use the “Filter > Blur > Gaussian Blur” filter. This filter will blur all images, leaving them with a Gaussian blur. The third way is to use the “Filter > Noise > Lowpass” filter. This filter will reduce the noise in an image, making it easier to see details and remove any artifacts.
