Once decided upon the concept there was one major problem that needed to be addressed. Although we had the specifics of the screen we had no physical measurements of the building or exact screen location, all of which are critical in order to make the perspective work. Attempts were made to discover these facts, but no research provided us with the detailed measurements we needed. So in order to gather such invaluable information we commissioned a photographer in NYC to take multiple shots from a multitude of positions. Once combined, we used clever mathematics to accurately plot the physical size and position of the screen on the building.
