When we say that the photograph pixels measure radiance here, does that mean they're able to measure both the amount of light and the direction of the light that's hitting the pixel, since radiance is along a ray?
Or similarly, would a pixel be able to distinguish between two rays that arrive at the same pixel, but have different directions (assuming that both rays are somehow able to pass through the pinhole, like if we enlarged the pinhole a bit)?
