Any time you are photographing under constant lighting conditions, you can save yourself time changing exposure settings by switching to Manual exposure mode. The day I made this image of Emily's spur and boot, the sky was completely overcast. The light remained the same during the entire afternoon. So I set the ISO to 400, the shutter speed to 1/125 second and the aperture to f/8, and shot away. Doing so let me focus on composition and expressions and not worry about constantly adjusting the camera's controls.
