Exercise2.2 Are you sure it’s real?
You know about color and now you know how you can tell a real, three dimensional (3D) object like an actor, from a flat picture (2D).
What if we combine an actor on a stage (3D, reality) and movie playing behind them (2D image of reality)? You’re fooled into seeing a real person in an unreal scene. Such visual effects (VFX) happen in Zoom and more often than you realize in movies. You may have heard it called “green screen” (aka, chromakey), a common example of combining 3D and 2D images to create “realistic” VFX, which you watch ultimately as a 2D screen image in a movie or video.
Describe chromakey. I already know what Wikipedia says. What do you say? Show me.
Describe rotoscoping relative to chromakey as a VFX, in terms of positive and negative space.
What part does the point of view (PoV) of the camera shooting the actor on the chromakey stage have relative to the PoV in the scene that’s playing in the chromkey area (the insert footage)?
What happens if the actor is supposed to walk around the corner of a building in the insert footage, which was shot from a single PoV (locked down)? Is there a way the actor can walk away toward the green screen? What relation does action in 3D space play in the successful illusion of chromakey VFX?
What relation does lighting and shadows in both areas (stage and insert footage) play in the successful illusion of chromakey VFX?
Again, use text with helpful use of typography and simple diagrams to explain each prompt.
