INTERPRETING LIGHT

Light not only povides illumination within art, but colors also depend on it. It is extremely diverse because its intensity, spectrum, frequency, speed, and wavelength are all properties which can be controlled by the artist. A particular employment of one or all of these properties can drastically change the symbolism within a piece or even become the art itself.

Merz's quote [from Art & Electronic Media] illustrates that the choice between either natural or electric light can also alter the purpose and/or affect of an art piece. Using the luxurious, flashy electronic light is quite enticing and draws viewers in whereas natural light is softer and humbling.
I like this idea of psychological control over one's own art.

Yes, most interpretations are quite subjective.
But consider this: How much of your reaction to an art piece is truly original and how much may be transcribed to you?
