Rendering 101 pt. 3: Theory- Camera Models & Film Response Curves (Patreon)

When taking pictures, we're usually using some sort of camera, no matter if it's in your cell phone, if it's a nice DSLR or that old school Polaroid camera you hipsters keep showing off with.

When we're creating computer generated images, we need a camera too. And usually the cameras we encounter in our 3D tools are based on what we use(d) in the real world.

Which means that most camera models we encounter in CG are based on old school analog film cameras. This Video will give you a theoretical overview of the camera models most frequetly used in CG.

EDIT: Uploaded the example file used to illustrate the camera models.
