This is the abbreviation for “Field Of View” and describes the visible section of the scene in degrees. Larger values create a wider impression; small settings will narrow your view, giving more focus on a certain object. "FOV" is connected to "Focal length".
Shutter
This parameter determines for how long the camera's "sensor" will be exposed to light and it is also responsible for motion blur effects. The value is 1 / Shutter value. Higher values create darker images and shorter motion blur streaks.

stop
Controls the size of the aperture of the camera "lens". This parameter affects both exposure and depth of field. See → Camera page - F-stop section (Maxwell Render) for an indepth explanation.

Here you can adjust the the physical camera "lens's" field of view (FOV) and depth of field (DOF):. Both, "FOV" and "Focal length" are directly connected.
- A small focal length lens (15-24mm) is said to be a wide-angle lens; its DOF is wide too.
- A large focal length lens (80-200mm) is said to be a telephoto lens.
- Smaller settings can lead to distortions.
ISO
This is the camera's light sensitivity. The lower the ISO, the more light is required to get a well-lit image. In contrast to real films/sensors, RealFlow's ISO does not add noise to the image.
