University of St Thomas student, the "Roamin' Roman", who blogged stateside under the nom de plume "Veritatis Splendor" has been studying in Rome the last nine months. Actually, I don't think she has had the time to study much because she has taken about 7 jillion photographs and has blogged them with such wonderful descriptions that she just might save you the cost of a trip to Rome. And I don't think the St Thomas Rome branch offers courses in photography.
Take a look and make sure you've blocked out plenty of time. You won't believe what a wonderful experience it will be! Start at the beginning and move forward so then her commentary will make more sense.
