LIGHTING: Indirect Lighting with HDRI


LEARNING TARGETS:
»   I  can light a subject with a simple 3-point lighting  configuration.
»   I can implement 3D text in Maya

EXPECTATIONS:
»  » 

I am looking for an image of: (with all the same camera and position)
  • 1-Point Lighting
  • 2-Point Lighting
  • 3-Point Lighting
Watch video on 3-point lighting.  http://www.youtube.com/watch?v=AcMX1RcNRYA 
  
 

Overall Goal, post 4 renders to your blog: 1-point Lighting, 2-point Lighting,  3-point Lighting, & Final Render

General Steps for Key Light:

Talk about indirect lighting. NOTES!
In our case, the main light source is in the ceiling. Look at the top your hand, why is the bottom of your hand not completely in the shadows?

Reflecting Light is a transverse, electromagnetic wave that can be seen by humans.
 
The photon the basic "unit" of light

Any light that you see is made up of a collection of one or more photons propagating through space as electromagnetic waves. In total darkness, our eyes are actually able to sense single photons, but generally what we see in our daily lives comes to us in the form of zillions of photons produced by light sources and reflected off objects. If you look around you right now, there is probably a light source in the room producing photons, and objects in the room that reflect those photons. Your eyes absorb some of the photons flowing through the room, and that is how you see.

For instance, a photon in the visible spectrum would contain an energy of approximately 4 X (10 to the power of -19) joules Thus, a perfectly efficient 100-watt light bulb would emit approximately 2.5 X (10 to the power of 20) photons per second.

If I put a chrome ball in a black room, what would it look like? Reflective material is directly dependent on the environment.
