After the frame appears, you can pause the game and adjust the camera. I'll echo what some have said by stating that zooming with the scroll wheel (the "z" key does this, too, if I'm not mistaken) and adjusting the pitch of the camera can help, too. And you can use the arrow keys or hold the right mouse key down to "walk" the camera closer to the subject, and in the process the camera will pass through any walls that might be in the way.
