If you want to create renders from your simulation directly within RealFlow using → Maxwell Render then you can use the physical camera model. Here are the parameters:
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. Smaller values create brighter images and longer motion blur streaks. By default, is value is taken from the → camera's own “Shutter” parameter, but it can be overwritten here. The unit is, as in real world photography, 1 / shutter value seconds.
...
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.
Focal length
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.
