I highly recommend Lightroom for anyone serious about photography.  There are no copies currently in the campus bookstore but you can get from Adobe directly or other academic software outlets. Lowest price I’ve seen is ~$52 (academic) from Amazon.

Read carefully the limits — you have to have an appropriate academic ID to activate it, regardless of where you buy it.

Make sure you get Lightroom 4.

PS: Nevada Weir on the LR site is my friend and mentor — she introduced me to LR and uses it for her own images.
