Available light

During the daytime photographers have the luxury of sunlight as discussed in 5: Natural light, however moonlight is no where near as powerful and so other available sources of light are required to make an exposure. This variety of light sources can add to a photograph or present problems with a great deal of uncertainty. Something Freeman (2004, p. 101) agrees with by stating that:

one of the issues was whether to sacrifice detail by opting for a faster and so grainier emulsion, or accept some movement blur by staying with a fine-grained emulsion and using a tripod for steadiness.

This is an area which I have always struggled in with photography. Taking photos in poorly lit conditions always seemed to blur easily and using the camera’s flash would sometimes create too harsh an image which darkens the background too much. My images would also have a yellow/orange tinge which gave an unnatural feel to my photographs.

Freeman (2004) explains how the age of digital photography has meant that there is no-longer a need for forward planning when shooting in these lighting conditions, however knowledge of how this lighting affects the image is extremely important in order to adapt to the different lighting situations.

The different types of available light you might encounter include:
