| Exposure | |
There is no such thing as a correct exposure, only exposures that work for particular images. More often than not, however, a technically correct exposure will be the one that works. Do not forget that all meters are calibrated to give an accurate reading with subjects that have an 'average' range of tones. There are times when it is appropriate to make a picture that is darker than it 'should' be. This gives a low key effect. In this sort of picture it is necessary to deliberately underexpose the film. Likewise, sometimes a subject will look best if it is deliberately overexposed. This will give a high key effect and the picture will be lighter than it should be. On dull days it can be a good idea to exclude the sky completely from the picture when metering and give an extra exposure of between 1 and 2 stops. This will pep up the photo and give pastel effect. When using a digital camera, or slide film, the biggest crime is to burn out the highlights. If you do this there is no way to bring them back. You might need to use a grey graduated filter, use contrast masking or digital blending if the range of tones in the picture is too great. |
