"""Radiance to achieve saturation.
Calls the :func:`~emva1288.camera.routines.get_radiance` function

Parameters
----------
mean : float, optional
The saturation value of the camera. If None, this value
is set to the :attr:`img_max` attribute.
exposure : float, optional
The camera's exposure time at which the radiance
for saturation value will be computed. If None, the
exposure time taken will be the camera's actual exposure
time.
Returns
-------
float :
The radiance at which, for the given saturation value and
the given exposure time, the camera saturates.
