What types of cameras are there?

2 Types• Film/Analog• Digital

0Film and digital cameras have similarities and differences.

0The main differences between the two are in the technical aspect of creating the photo.

Types of Cameras

0Film uses a chemical reaction to create the image on the film, whereas a digital camera uses a series of mirrors to reflect the image on a digital storage chip.

Film

0 A film camera is made of three basic elements:1. Optical (the lens)2. Chemical (the film)3. Mechanical (the camera body

The 3 elements combine to make a printable image

Two Types: Point and Shoot & Single Lens Reflex

0 Point and Shoot (P&S)0 The viewfinder provides a rough idea of what is in view, but not the real

image.

0This occurs because you are not looking through the lens

ACTIVITY: Have students make a viewfinder with their fingers. Have them simulate a camera by closing one eye and holding their simulated viewfinder over their open eye. This is what taking a P&S photo is like.

Single Lens Reflex ( SLR)

0You see the actual image that will be exposed onto the film.

0Great for capturing images with real impact.0Provides more control and better images than P&S.

Advantages of an SLR Camera

0Precise framing-what you see in the viewfinder is what is recorded on the film.

0The range of lenses make the SLR very versatile. 0Precise exposure measurement because the light-

sensitive cells measure only the light coming into the lens

Disadvantages of an SLR Camera

0Noisier than a compact because of the mirror in front of the shutter moving.

0Mechanical complexity makes them more prone to failure.

0Heavier and more awkward. 0More expensive

Digital0 Digital

0 A digital camera records images electronically using a built-in processor.

0 Has a lens like an analog camera0 BUT, the lens refracts light onto computer chips rather than film.0 Types of Digital Cameras

0 Similar features to film counterparts0 Rely on electronic processing and storage0 Point and Shoot (P&S)0 Most feature LCD screens and advanced zoom lenses0 SLR0 Can Switch out lenses

Parts of FILM Camera

Parts of Camera Vocab

0 Lens: Collects light reflected from the subject and focuses it at the exact point occupied by the film.

0 Aperture: an adjustable opening in a disc inside the lens.  The size of the aperture determines the amount, or brightness, of light that reaches the film, and hence affects film exposure

0 Shutter: a physical barrier in front of the film that opens for a timed period. The shutter thus determines the amount of time that light passing through the aperture is allowed to act on the film.

0 Viewfinder: allows the camera to be accurately pointed at the chosen subject
