This mode uses up to 256 shades of gray. Every pixel of a grayscale image has a brightness value ranging from 0 (black) to 255 (white). Grayscale values can also be measured as percentages of black ink coverage (0% is equal to white, 100% to black). Images produced using black-and-white or grayscale scanners typically are displayed in Grayscale mode.
Although Grayscale is a standard color model, the exact range of grays represented can vary, depending on the printing conditions.
These guidelines apply to converting images to and from Grayscale mode:
• You can convert both Bitmap-mode and color images to grayscale.
• To convert a color image to a high-quality grayscale image, APE discards all color information in the original image.
• The gray levels (shades) of the converted pixels represent the luminosity of the original pixels.
Simply click on Grayscale control to make changes of your photo.
