- Cameras with NO apparent focus control utilize the “Pinhole Principle” to obtain a focused image.

Pinhole PrinciplePinhole Principle

- We see reflected light in all directions- A single ray of light can not be out of focus- We can eliminate all but a single ray of light with an opening that is extremely small (a pinhole) resulting in a focused image HOME

Viewing SystemViewing System- Method photographer uses to see approximate scene which will be captured on film

- May consist of one or more lenses

- Criteria under which all cameras are classified
