If you have a chance to visit a Turrell Skyspace, do it. There's one in my town and I've enjoyed it many times. The New York Times has an article highlighting some exhibitions that might be within your travel range so you can experience it yourself.
“LIGHT is this thing we usually use to illuminate other things,” said the artist James Turrell, who first considered the presence of a beam of light cast from a slide projector during art history class at Pomona College in the early 1960s. “I’m interested that light has thingness itself, so it’s not something that reveals something about other things you’re looking at, but it becomes a revelation in itself.”
As an architectural designer, paying attention to light and what it can do inside a space is only part of the process of design. The fun part is what you can achieve with it as a design tool. It's one of the most flexible and underused tools in our toolbox. It is one of those things that, along with many other necessary ingredients, can create a moving, human experience which to me is what architecture is all about.
There are some great architects that use(d) light to their advantage - Louis Kahn, for instance, was a master whom I greatly admire.
If you decide to go, let me know. I'd like to go back and experience with you.
Here are some pictures I took on my last visit as the colors shifted and completely changed my perception of the sky behind.:
