Trying to See the Light

At the last minute, my teaching assignments were altered due to changes in enrollment. I'm shifting gears and getting ready to teach Photoshop CS4 instead of teaching Photoshop Lightroom 2.2.

For the past few days, I've been trying to see the light relative to preparing for this assignment change. I think I am starting to see the light. The lights, above, are from a church in Paris.
