A!!!!!
Look close at that URL. Here, I'll bold it.
dfpphotography.com/wp-login.php?redirect_to=http%3A%2F%2Fdfpphotography.com%2Fdfpphoto%2Fwp-admin%2F&reauth=1
Home and Site URL need to both be changed to http://dfpphotography.com/
I bet her site WAS installed in http://dfpphotography.com/dfpphoto before
