Defining our goals
Before we create any kind of lighting setup in the scene, we need to first of all create
our definition or vision regarding what we want to accomplish in our final render(s). At
the risk of starting to sound a little repetitive, it is important that we get this created so
that it can serve as the guide or blueprint that we use as we move through creating
this somewhat different lighting setup.
Observation is crucial
Now, while a definition created entirely from our own imagination can be used as a
blueprint for our scene, it isn't generally speaking the best way to go about creating a
document that, as we have noted a few times already, is fairly important with regards
to the success of the project.
Even if we are working at creating a completely fantastical lighting setup—something
that doesn't exist in the real world—we still need to create it based on the reality of
how light works. The behavior of light is something that those who view our images
will be incredibly familiar with; after all, they see and make use of it every day of their
lives, and even though they may not fully understand the physics of how it works, they
will instinctively spot mistakes in its behavior.
Once again then, before fixing on the definition that we will use to create the mood
or feel for a particular scene, going ahead and gathering reference notes and photo-
graphs should be considered an essential part of the process.
In regards to this particular scene, if you have a local gallery or exhibition space that
has nighttime sessions (ones that are open to the public, of course), be sure to go
along and take notes regarding important elements such as the style of the lighting
used and the mood it appears designed to create.
Make a note of the number of light fixtures in the space, the positioning, and even
their coloration. If you do find a very particular lighting effect that you realize would
look very nice in the render you are trying to create, be sure to document as much
about its setup and apparent creation as you possibly can.
If a field trip such as this is not an option, then we can make good use of image
searches on the internet, taking the time to compile a varied collection of images that
