Here is a brilliant Natural Light vs Flash comparison :-
In this video, Manny Ortiz showed me some amazing examples of what a single flash can do to give a very different look to a picture compared to natural light. He shoots the same scene in both natural and artificial light, demonstrating the amazing capabilities of one flash, deepening my knowledge in the possibilities of flash. Shooting during the sunset, the flash allows both the background(sunset) and subject(model) to be “correctly” exposed, with the beautiful warm colors of the sunset showing and a well exposed model, when in natural light the background would have been over-exposed and washed out if the subject was well exposed. This is done by exposing for the sunset instead of the model, and the using the flash to illuminate the model, producing a very beautiful and dynamic image.
