Darkness is said to be the polar opposite of brightness or the absence of visible light. The appearance of black in the color space also represents darkness. We perceive color as combinations of light and darkness, unless one of them dominates our space. Darkness can evoke rather negative emotions and perceptions such as evil, ominous shadows and depression. Satan has been called the prince of darkness. Dante described hell as solid darkness stained. It is interesting to note that when we mix either the three primary colors or the three secondary colors, they will absorb all visible light and create black. Shadows add perspective around light, such as when we seemingly observe shafts of light emanating from behind clouds that drift in front of the sun.
Light colors reflect light and appear bright, compared to darker colors that absorb photons and do not reflect much visible light. Since visible light cannot be created or destroyed, it can only be converted into another type of energy to be reemitted such as heat. The reemitted frequency may be still be relatively bright, but not one that the human eye can perceive. However, when the iris in the human eye dilates it permits more light to enter to improve our night vision. Since these cells regenerate, prolonged exposure to less light generates more rods and cones that can adapt.
Darkness can play tricks on the mind as well as the camera lens. I took the image above at night while I was attempting to capture the Super Moon of 2012. I was using a telephoto lens and the optics got a bit confused as I zoomed in on the larger image of the moon rising over the trees in my backyard. The resulting photo turned out to be more than a little skewed, but I liked the imagery, so I kept it and published it here. Could it be a vision of the darkness that was over the earth when our creator first spoke light into the world and He separated the light from the darkness? And there was then evening and morning on that first day.
