Photography has taught me that brightness and darkness are merely a reaction to one another. Sometimes, just making a few elements of an image a little darker, you make other aspects brighter and more luminescent. Take the example of this photo, which uses varying degrees of darkness. In our lives too, darkness gives us perspective and helps us seek out light.
Truly, it is in the darkness that one finds the light, so when we are in sorrow, then this light is nearest of all to us.Meister Johann Eckhart
