hello, so i am designing the light for our production of 12 angry men, and i need to have a light come through a window (with the shades down). at the beginning of the play its morning and at the end its dust. i was thinking of using an ellipsoidal and just dimming it as the play goes on. but also was thinking about using a fresnel. i was wondering which would be best. oh and all our fixtures are colortran.
