THE VESTIBULAR SYSTEM The eyes are not alone in giving sensory information to the brain for movement assessment. The vestibular system, including components of the inner ear, is also involved. In the inner ear are semicircular bone canals. Within these canals are membranous ducts with protruding pouches. These bony canals are filled with fluid in some places, and the membranes are directly attached to the bony structures in other areas. The membranes have hair cells that project from them. Moving the head changes the orientation of membranes but leaves the fluids to orient as they were before.

To understand photography, we must first grasp the concepts behind film. As discussed in Chapter 1, light is an electromagnetic vibration of which we see only a narrow portion, called the visible spectrum. Even though today we use film, which is really a piece of cellulose acetate (plastic) coated with silver halides (mainly silver bromide, silver chloride, and silver iodide), the picture-taking principle has remained unchanged from the day, circa 1800, when a young English chemist named Thomas Wedgwood exposed his first paper emulsions.
