We took this shot the same night as "Forbidding Beauty". While we were working on the photo I wanted just for the heck of it I asked Jenn to snarl for a couple shots. I had some spare time after so I added some fangs. Then I made her a little pasty because that is what the undead are, right?
So I used which lens? The 50mm, you're so right! 1/125th sec at f5. You notice the higher shutter speed? That was to make sure the background was darkened.
