I need to make venetian blinds change the view out of a window. So basically what I mean is, that we are looking out a window at a sunny view then turn the blinds to see a wintery view... so you actually don´t see the blinds only the views changing...
it needs to look totally "realistic" or real, so with shadows and all on the blinds
don´t know if it is best to film blinds and some how change them out for the view or if there is a way to make this effect real in after effects?
Dave's right, to get the HDRI reflections and raytracing of the blinds, you'll need 3dmax or Maya with with v-ray sun(which in my opinion is the closest thing you can get to photorealism).
AE can only fake reflections as being upside down, and certainly can't create 3-D landscape environments. It's only a compositing tool, after all. Now if you have both footages and are content to settle for un-photorealistic blinds, you can use AE.
I had another thought. You could shoot real blinds in front of a large greenscreen, then simply key some footage in with light wrap. Then use the blinds as a displacement map or shadow overlay for the actual footage.
Thanks for the response... I think I´ll try the green screen real blinds first, it was something along the lines I was thinking... the director on this project is mega analog, and doesn´t like using 3D, so I think I can convince him using this method..
