In conventional photography, whether digital or film, reader cannot make an image of subject matter that is not there. Similarly, they cannot print what is not in the digital file or negative. If the highlights are blown out or the image is underexposed, or if the film has been over- or underdeveloped, it is almost impossible to obtain the good-quality photographs they want. When enlarging their negatives in a conventional ‘wet’ darkroom they will find that it is easiest to print those that contain the widest range of tones, from the darker areas through to the highlights. In some cases, they may want a negative that accentuates the highlights to produce a picture that has a particular graphic quality. A great deal of photographic terminology is similar whether it is analogue or digital. For example, blown highlights, grain, burning and dodging, flat and contrasty, and so on. New terms, like luminance, saturation and noise, have arrived with digitisation.
