parallax effect?

#1

when do you use the parallax effect?
I heard if you don’t have a 3D object to project the picture on you need to distort the picture to give that parallax effect. Anyone know exactly how that work?
You need that too if you project your image on 3D objects?

Parallax is a displacement or difference between objects and distance, so if you are working let’s say in this matte painting where you camera is doing tilt up or tilt down movement but it stays on its position, or if the camera orbits the view but again it stays in the same position ( Nodal camera ) , no matter if it is moving in 360 º there won’t be any parallax, but if you are moving your camera let’s say dolly in or out, traveling or fly through you will see a lot of parallax and movement related to where objects are positioned in distance one from the other, in matte painting when you have parallax you will need to project patches or new paintings to cover up that gap, depending on how your camera movement is , it might take several projections one over the other until all the parallax is covered with new image info behind every element . sometimes depending on the matte painting even if there’s a lot of parallax in the foreground you can make it with just a single projection for the whole background. check this image
