1.   Do not directly touch or handle lights that are in
     use or have just been used without protective
     clothing.

2.   Lights are extremely hot and consider that this
     heat is also capable of setting fire to objects or
     fabrics located near to a lighting source.

3.   Check electrical connection points and make sure
     that all cables are safe and secure.

4.   Check emergency exit areas are clear and
     accessible.

•    This assessment has been designed to improve lighting skills.
•    In pairs or as a group etc. study creative lighting techniques.
•    Light in 3 different locations using your own research and the lighting techniques
     discussed in the lecture.

•    Use a wide shot to show the lighting setup.
•    Then show how lighting techniques have improved your results.
•    For example a shot prior to lighting and then after the lighting setup.

•    Consider using the gels, reflectors, silks etc.

•    Practice lighting until you are satisfied with the quality of the results.
•    During the group peer assessment you will critique both the quality of lighting and
     shot composition.

•    Use this opportunity to develop ideas for the final lighting assignment.

Key Light
Main light.
Usually the strongest and most influential on the look of
the scene.
Placed to one side of the camera/subject so that this side is
well lit and the other side has some shadow.



Fill Light
Secondary light placed on the opposite side of the key
light.
Used to fill shadows created by key.
Fill usually softer and less bright than key.
Can also use fill light as a flood instead of the key.


Back Light
Back light placed behind the subject and lights from rear.
Instead of direct lighting (like key and fill), it provides
definition and subtle highlights around the subject's
outlines.
This helps separate subject from background and a three-
dimensional look.
