I have a very interesting upcoming mapping project but there are some serious technical downsides on it. The mapping is supposed to take place on a castle which is on a hill. There is no clean view of the castle or anywhere i could place the projectors close to it. So the only solution is to go far away. But seriously far. The only spot i can put the projectors are at the rooftop of a hotel which is 530 far. The barco calculator gives me a lens (xld 5.5-8.5) which is supposed to be ok with this distance. The projectors i want to use is a double stack of BARCO HDQ 4K35. Has anyone tried this distance before? Is seems a bit scary...
I am attaching the view to the castle from the rooftop i believe is ideal for the mapping which is 530m away.
Thanks in advance,
