         | direction only, arrives at the sensor. Some also ensure only
         | light oscillating in a specific way goes through
         | (polarization), or of a specific frequency (with color
         | filters).

         | This filtering is necessary for us to produce useful data from
         | the total chaos that is the actual light field - aka all the
         | light bouncing and going in all directions at once - where 'us'
         | are our normal human brains.
         | 
         | Other ways of handling it though if you can use different types
         | of information processing.

       | Why use one word when you can use 3 with less precision?
