To achieve a custom pinhole camera effect with a custom bokeh in Arnold Raytracer, you can follow these steps:

1. Set the render camera with a focal length around 50 (or as needed)
2. Set the F-Stop to a high value (e.g., 22).
3. Set the focus distance as you require
4. Turn on DOF
5. Place a plane a few cm in front of the camera.
6. Texture the plane with a transparent shape at the center of it. (Transmission with no specular roughness)

The light field consists of the total of all light rays in 3D space, flowing through every point and in every direction.

How to Record a Light Field

• a single, robotically controlled camera
• a rotating arc of cameras
• an array of cameras or camera modules
• a single camera or camera lens fitted with a microlens array
