Changing the Camera Position

To set the lights as well as to find a proper camera position for the picture, an efficient handling of the camera is needed.
The camera's position can be changed by clicking with a mouse button into the 3D graphics view and dragging the mouse: Try to zoom very close to the peptide, then very far away, and compare the brightness of the scene of both camera positions.

A roughly sensible camera position can be found by centering the camera on the entire peptide:
Find the widget with the name Structures and highlight the System by clicking on its name ("ARND").
Then, press the right mouse button to open a context menu and press on the Focus entry.

Press Next to continue.
