File:Second Severn Crossing pano 2 s-cb.jpg

This image is a version of Image:Second Severn Crossing pano 2 s.jpg with slightly greater contrast and brightness. Note that contrast and brightness are things which vary based on the aperture and shutter speed settings of the camera, and the film speed. These concepts refer to film cameras, but digital cameras imitate them. When a film camera is used, the aperture, exposure time and chemicals used in the darkroom when turning the negative into a positive also make a difference. However, the manipulations of this image were done digitally.
