The tone in this image is created by the very dark areas within the trees but then the very bright areas created from the streetlights.

This image shows tone of a natural image and the tone is the difference in lightness of the object. There are very dark areas and very light ones too.

Tone is shown by the contrast between the very dark background and very bright fence and sky. The contrast shows both light and dark tones.

This photo shows tone by the lightness of the trees to the left of the image and darkness on the right hand side of the image.

My definition-

 Tone is the variation in lightness and darkness across an image. The different use of tone can create mood and emotion, for example, dark tones can create mystery.
