+  """Class for reading images from a gPhoto2-compatible camera.
 
-  The CameraGphoto2 block is meant for reading images from a
-  Gphoto2 Camera. It uses the :mod:`gphoto2` library for capturing images,
-  and :mod:`PIL` for converting BGR images to black and white.
+  Such cameras include for example most of the Nikon and Canon models. This
+  class is designed for low-frequency acquisition of high-resolution images.
 
-  Read images from the all the gphoto2 compatible cameras  indifferently.
-
-  2 modes are currently implemented :
-      'continuous' : take picture as fast as possible
-      'hardware_trigger' : take picture when button is clicked
+  The class is based on the :mod:`gphoto2` Python module, that is necessary for
+  using it. It can acquire images continuously, or following external triggers.
 
   Warning:
-    Not tested in Windows, but there is no use of Linux API,
-     only python libraries.
-  .. versionadded:: ?
+    This class was only tested on Linux, it is not certain that it works on
+    Windows or macOS.

+  .. versionadded:: 2.0.6
