Thinking about the use of light in art.

When I think of light in art, what instantly comes to my mind is how the artist wants to emphasis something important. For example is there is a landscape that is of a field completely barren except for one flower in the middle, the artist would chose to shine the light on the single flower to emphasize the importance in the picture. When I think of music, sunshine can refer to happy things or something that is going to help you get to a better place. Also, when people think of light it can symbolize Heaven or God. Usually when people say don't go to the light, it means don't slip away and go to heaven. Also if you go into any Catholic church and look on the ceiling there are portraits of god and other heavenly things with light always shining behind them. Light can also make the piece of art very strong because people are drawn to light!
