    Opposition effect    

 

The opposition effect is the effect that some parts of uneven surfaces seem to be brighter than others when the sun (or any other light source) is directly behind you. This is because when the light source is directly behind you, the shadows of the parts around the shadow of your head are not visible, making these parts look a lot brighter.

The rocks around the shadow of my head look a lot brighter than the surrounding rocks. (2013-11-23)

 

[ normal || camera moved ] ⇛ When you take a photo, the opposition effect is not around the shadow of your head, but around the shadow of your camera. (2015-04-18)
