I know there's a way to do that, but I don't know exactly how. Was never curious to find out.
When I want to take nice screens, i usually record a track of the action and take the screens when I replay the recorded track.
You have many options how to play the tracks. You can slow it down, change views, remove icons and you also have the option to play it without the text and stuf. Is quite easy that way and you can concentrate on the flying and fighting in the mission and concentrate on the screens when you take the screens.
Have fun.
