13.5. Hot lights

After talking about flash all the way through this book, what about hot lights? It seems obvious that regular incandescent or fluorescent lighting should make perfectly good light sources for photography.

It's true that hot lights can be used for most forms of photography. Prior to the invention and widespread use of flash equipment, most studio portraits were done with continuous forms of electric light. Hollywood glamour photos of the 1940s, for example, were done using large 8 × 10 glass plate negatives on sets lit by the same huge Fresnel lens spotlights that were used on movie sets of the age.
