A big nod and a hat-tip to RonC, a member of the Glamour1 photography forum, for providing a link to an excellent Canon EOS FAQ site.
The Canon EOS FAQ site is chock full of answers to, uhhh... a plethora of frequently asked questions. It's one of the best I've seen. Don't let the title fool you: While it says it's aimed at beginners, its lengthy list of FAQ-answers are a practical resource for many levels of Canon shooters and worth perusing, exploring, and bookmarking. The site also includes links to other resources, like PhotoNotes.org: A Dictionary of Film and Digital Photography. Although the term, pretty girl shooter, is not listed amongst its many definitions, PhotoNotes.org is another excellent resource for all levels of shooters.
As long as I'm providing links today, the Strobist also deserves a hat-tip for posting a pretty girl shooting-worthy link to a detailed explanation of the history and artistic use of Chiaroscuro.
The pretty girl with the big headlights accompanying this is Jada. I shot this in my studio about 6 months ago. As you can see, I kept the mainlight centered and up high and drove the exposure on her face. In post, I decided to play around with a somewhat different approach -- at least for me -- to processing the image: I converted to B&W using the Channel Mixer. After that, I used the Photo Filter tool to add and blend both sepia and yellow tinting. Not sure if I'm sold on doing this and I'm far from perfecting it but thought I'd throw it up here anyway.
