At what time was this picture taken? Guess before you read further.

The sunlight spelling through this window is a fake. The photo was taken before sunrise at 5:00 am, before the first gleam of daylight. The light comes from a lantern outside the window. The effect was archived by using accentuation filters. Adjustments of exposure and color were made.
