If we define monochrome photography, we would define it as an image composed exclusively of shades of one color varying from the brightest to the darkest hues.

The best example of a monochrome image is a sepia photo, which has its origins in film photography. However, grayscale is a far more accurate term. A truly black and white image would simply consist of two colors—black and white.

Grayscale images are created from black, white, and the entire scale of shades of gray. All grayscale or black and white images are monochrome as they are made of varying shades of only one color—black. However, not all monochrome images are grayscale as monochromatic images can be made of any color.

In modern digital photography, there are two principal ways of producing grayscale or monochromatic photos. By activating one of those modes, you instruct your camera to produce black and white or monochrome images at the time of shooting. The way the camera works is first by capturing the image in color.

Finally, it saves the captured photo as a JPEG image.

The advantage of this approach to black and white photography is that you instantly have a black and white photo and no further conversions are necessary. The disadvantage of in-camera black and white shooting is that during the conversion the camera discards all the color information and turns the uncompressed RAW file into a heavily compressed JPEG format.

This means that if you are not happy with the final photo, you cannot change it back to a color version.

For each pixel in a cyan-magenta-yellow CMY grayscale image, all three primary pigments are present in equal amounts. The lightness of the gray is inversely proportional to the number representing the amounts of each pigment. In some systems that use the RGB color model, there are 2 16 , or 65,, possible levels for each primary color. As with 8-bit grayscale, the lightness of the gray is directly proportional to the number representing the brightness levels of the primary colors. As one might expect, a bit digital grayscale image consumes far more memory or storage than the same image, with the same physical dimensions, rendered in 8-bit digital grayscale.

In analog practice, grayscale imaging is sometimes called "black and white," but technically this is a misnomer.


In true black and white, also known as halftone, the only possible shades are pure black and pure white. The illusion of gray shading in a halftone image is obtained by rendering the image as a grid of black dots on a white background or vice-versa , with the sizes of the individual dots determining the apparent lightness of the gray in their vicinity. The halftone technique is commonly used for printing photographs in newspapers.

These are hue, saturation and brightness. In a grayscale image, the hue apparent color shade and saturation apparent color intensity of each pixel is equal to 0. The lightness apparent brightness is the only parameter of a pixel that can vary. Lightness can range from a minimum of 0 black to white. Please check the box if you want to proceed.
