Photoshop 101: Convert a Color Photo to Black & White
When taking pictures with a digital camera, by default the picture will be in color. Most point and shoot cameras along with a few DSLR offer a black and white mode. This is great if you’re looking for low contrast and flat pictures. To get the most range from an image, take the picture in color and convert it to black and white with Photoshop or other imaging programs.
