Something I do when I feel I’m in a rut. Try shooting without color for a day, it will help train your eye. Set your camera to the B&W or monochrome setting and get used to seeing in Black & White. If your camera can capture NEF files, you can set your camera to write NEF + JPG—the JPG files will be B&W but the NEF files will be in color. Also, you will be able to view the preview images on the camera’s LCD in B&W.
