Motorized Iris Diaphram Film Movie Prop / Rotary Actuator / Sci-Fi/ as Aliens
They just placed the camera at a distance to either use forced perspective or a set of scaled size to achieve the effect. NOTE: This unit is opened and closed with the use of a 26v electric motor / actuator.
Please have a experienced electrician hook this unit up to power / control box.. Otherwise you may burn or short the electronics out which may be costly and be an all round bummer.. I used a simple 24v dewalt battery to open and close it for the pictures. You will probably want to add an AC or DC power supply with a rheostat and a switch for forward and reverse motor control. The Iris opening is 7.
Add the movie prop bump and a few dollars more. I included the screen captures from Aliens as an example of the use fo this type of iris in Hollywood films.
