In real life a 24″ x 36″ blow up of an 8″ x 12″. Best would be if a professional shot a very high definition picture. The problem with taking a picture of the poster is the picture pixellates – the black is actually a metal frame. Worse, the glass reflects. That white rectangle is actually a reflection of a door. Indoors the glass reflects any light and there are complicates if the camera adds a flash.
