Newbie here and just curious how many of you use a digital STILL camera to frame your shots--either for location planning or during production?

I Recently saw the making of Indiana Jones on DVD, and there was Spielberg using the viewfinder of a digital still camera (the LCD) to frame his shots. Seems so logical and has its advantages over the traditional director's eyepiece viewfinder seen worn around the director's neck for decades.

Anyone use one during production or pre-production.
