This terminology is self-explanatory; photography with whatever light is available. During daylight hours, this is no problem. Difficulties arise when light levels are quite low. Under such circumstances faster lenses or higher ISO settings often become a necessity. With film, higher ISO settings generally are accompanied with coarser grain and ISO 3200 is a limit that is hard to overcome. Here digital technology offers considerable advantages with some cameras offering ISO levels many times higher.
All in all, photography in low light is no problem, as long as we take the necessary measures to overcome the problems associated with this. Digital photography has the added advantage of allowing to experiment without adding to the cost of film and processing. The results can be outstanding photographs, much beyond the usual daylight snapshots.
