A Available Light 36 Available light is commonly associated with photography in low-light conditions. It is, however, any natural or artificial light that can be used by the photographer to get an exposure. The real distinction is that it is not photographic light ­ i.e. light that is added specifically by the photographer using flash or continuous light sources other than those already present in the scene. Available light is what some people refer to as `ambient' light. A good idea is to think of available light as `found' light. It then becomes the job of the photographer to exploit both its quantity and quality. The extraordinary light in this image is internally reflected from the inner stone surfaces of Houldsworth Mausoleum (located in the Glasgow Necroplois) on to the stone statue by a single, bright sunlit opening to the upper right. Image captured with a Canon PowerShot G9 at 18.9mm, 1/25 sec at f/3.5, ISO 100.
