Sensor and lens

Field of view – Horizontal perspective FOV in degrees.

Focal l. mm – The distance between the lens and the image sensor when the subject is in focus.

Film width mm. – Affects the amount of the depth of field effect. Increasing this value increases the depth of field effect size. This is useful for matching other parameters and output to various real-world cameras. Typical values are 36mm for a full-frame digital SLR and 25.1mm for an APS-C digital SLR.

Zoom factor – Zooms in the view without changing the Filed of View or Focal Length. Higher zoom values result in a stronger Depth of Field. This is useful when matching real-world camera footage.

ISO – Affects image exposure when photographic exposure is turned on. Increasing this value increases exposure and vice versa. Standard values used in photography are: 50, 100, 200, 400, 800, 1600, 3200.

F-stop – Affects the depth of field effect and image exposure (when using photographic exposure). Decreasing this value increases the exposure and the depth of field effect amount, and vice versa. Standard values used in photography are: 0.7, 1, 1.4, 2, 2.8, 4, 5.6, 8, 11, 16, 22, 32.

Shutter

Shutter speed – Affects the image exposure (when using photographic exposure) and length of the motion blur effect. The input value is reciprocal to the result, so to set the shutter speed to 1/125 s, input 125. Longer exposure times increase exposure and motion blur length, and vice versa. Standard values used in photography are: 1, 1/2, 1/8, 1/15, 1/25, 1/30, 1/50, 1/60, 1/125, 1/150, 1/250, 1/500, 1/1000.

Shutter angle – A different way to express the shutter speed, using the movie camera convention of rotary disc shutter angle. The value is an angle out of 360-degree range, for which the shutter stays open. This means that for example, a value of 180 degrees means the shutter is open for half a frame (which is 1/50 s for 25 fps).

Mblur duration – A different way to express the shutter speed, using multiples of the current frame rate (fps). For example, a value of 0.5 means the shutter is open for half a frame (which is 1/50 s for 25 fps).

Shutter offset – Offsets the time interval from which the motion blur effect is generated. The value is defined in frames, with 0 meaning that the center of the interval is exactly in the current frame, -1 meaning that the entire interval happens just before the current frame, and 1 meaning the entire interval happens just after the current frame.

Object visibility

Enable include/exclude list – If enabled, only nodes specified by include/exclude list are visible when rendering using the selected camera.
