Gondolas in Venice – St. Mark Square.
Usually we take advantage of some sort of light to take our pictures, it could be the light of a built in flash, a lamp, daylight or even the moon, but it is not so frequent to put the source of that light in the frame while composing. It may be very challenging sometimes, but it could add interest to the whole picture, especially when the lighting of the scene is peculiar. In that case it may be appropriate to show the source of the light, may it be a flickering candle, a trembling fire, or the first light of the day from a rising sun.
