The result is pretty much like grayscale mode. Convert to LAB mode and extract only the Luminance channel for your black & white.Some other methods of creating a grayscale image from a color image include: Trial and error may be the best method to employ. It can vary from one photo to the next and some differences may not be obvious until the image is printed. A desaturated image may be slightly darker and can lose some detail compared to the same image in true grayscale. In practice, subtle differences may be apparent. In theory, the same color image converted to grayscale and desaturated to shades of gray would be equivalent. The most widely used methods are using the "convert to grayscale" option or the "desaturation" (or "remove color") option in the image editing software. Trial and error is generally the best approach. Each has its own pros and cons and best uses. There are a number of methods available for getting a B&W photograph from a color photo. If the original image is in color, a graphics software program such as Adobe Photoshop or Corel Photo-Paint can be used to convert the color image to some form of black & white. Sometimes it is necessary or desirable to print or display Black & White (grayscale) photographs. Each color is made up of varying amounts of red, green, and blue. RGB images store values of red, green, and blue that would normally make up a color image. If not, it is often customary to convert to RGB and work with the image (editing in a graphics software program) in that format. Although it is possible to scan a color image in grayscale or take a B&W digital photograph (with some cameras) thus skipping the color stage, most of the time images we work with start in color.Ĭolor scans and digital camera photographs are typically in RGB format.
