LOW-LIGHT REQUIREMENTS
Digital photography offers several key benefits over film media when it comes to working in low light. The way in which sensors detect and process incoming light differs from how film emulsions react to light. At low intensity, illumination films are susceptible to the phenomenon known as reciprocity failure, when the same total exposure will produce an apparently less exposed image when the shutter is open for a long duration.
When working with exposures of several seconds, a
