LENSES
Since optical designs of photographic lenses (wide angle to telephoto) differ so radically we will not go into detail about optics. This lesson will cover a basic discussion of lenses and some good tips on lens use and care.
Lenses are designed to refract (bend) light rays. Here is a basic convex lens (crude [...]
HOW WE SEE:
The human eye looks basically like the crude drawing to the right. The lens at the left side of the eye focuses light rays onto the retina
at the right. The retina converts light rays into “electrical impulses” that are sent to the brain and our brain tells us we are seeing [...]
LESSON 1
Light is he primary working tool of the photographer. Light is the visible portion of the electro-magnetic spectrum. The spectrum (see colored bar above) starts from violet (left), the weakest of rays, all
the way to red which is the strongest of rays. (Which is why it is easy to get those

READ THIS PLEASE: Most adjustable cameras are quite similar. The camera in these pictures, a Nikon FE, is fairly typical. You should be able to use these pictures to find the controls on your camera however…
… we will also use a typical “Point and Shoot” camera in a few [...]
