Camera- and Lens-controlled Image Characteristics

• Field of view (angle)
• Depth of field (distance)
• Motion blur threshold (relative speed)
• Cleanliness (signal-to-noise ratio)
• Detail (perceived spatial resolution)

Underlying physical properties of the image composition

• Subject distance
• Light intensity at lens (illuminance)

Underlying physical properties/settings of the camera system

• Lens focal length (distance)
• Lens entrance pupil diameter/size (distance/area)
• Shutter speed (time)
• Capture area ratio
• Sensor resolution
• Lens sharpness

Intermediate properties

• Lens captured light (luminous flux) ~ lens entrance area x light intensity [lumens]
• Sensor captured light (?) ~ lens captured light x capture area ratio area x shutter speed [lumen seconds]
• Sensor captured light intensity (luminous exposure) ~ sensor captured light / sensor size [lux seconds]
