Advice for projection on building facade
Posted: Fri Jan 16, 2015 5:18 pm
Hi. I was hired to project on a building facade and also to produce some 2D content.
I'm quite new to this. The facade is not very complex, quite small and architectural elements are relatively flat but - for various reasons - the projector will be placed with the lens aligned to the top of the facade so I will need to use lens shift and - probably - slightly distort.
I need an advice on how to take a reference picture for content production to achieve the best result once in PB warper.
I should take the picture from the projector point of view (which will produce a quite distorted image since it's taken from top to bottom) and work on a distorted reference or - as I guess - it's better to take it from the viewer's point of view which is likely to produce a more flat image and then correct the distortion in PB warper?
