Since most of us are shooting in real world situations and don’t have too much control over the environment, changing the lighting and exposure levels of the film can be really helpful tool. This is particularly true for those not using dSLR or other cameras that do not have exposure settings that help correct for the lighting situations of a particular shoot. It is important to note that this different from using the color correction workspace to change a films luminescence. While this can be used to correct certain problems like over-exposure, it is unable to change specific lighting elements within the shot.

Changing the lighting of a scene follows a fairly similar process as the color correcting techniques discussed in the CS4: GS 07. There are a lot of different options in changing the lighting and exposure levels of a piece of film, but for this post I will be focusing on the “spotlight” technique.
HOW TO USE SPOTLIGHT:
Implementing the beginning technique is exactly the same as any other effect. Find the video effects, then click the “adjust tab.” (This part can be seen at the 1:118 mark of GS07). In this tab will be the lighting effects. Pull the effect onto the clip you want to edit.
This screenshot, taken from the tutorial, shows what the scene looks like without any editing.
In the lighting effects tab, there are a few different options to work with, but for now just work with “light 1” by clicking the drop down tab next to it. In here you can select the kind of lighting effect you wish to use, like spotlight.
Once you select the spotlight effect there should be a large oval section of light that appears on the clip.
You can edit the direction, intensity and other factors of this effect easily. Right next to lighting effects there is a little box, by clicking on the box, you expose the parameters of the light on your shot.
With this box you can edit how wide, tall, or direction of the spotlight effect. You can also change most of these parameters in the effect box. Most of the changes you will need to make will be based on what your needs are for the particular shot, so playing around with these settings is really the best way to achieve the look you want.
