2. EXPOSURE FACTORS: -intensity of the light in the environment -aperture (see Chapter 4) -shutter speed (see Chapter 5) -film speed (ISO) (see Chapter 1) In other words they can BALANCE each other STOP for STOP. See page 71 in your text book for a list of “full” f-stops and shutter speeds. Think of the “correct” exposure as adding and subtracting light using changes to shutter speeds and f-stops to keep the amount of light reaching the film appropriate to give the negative a workable density RESOURCES: David Likes Video Presentation. F-stops Shutter speeds GOOD NEWS!!! Shutter speeds & f/stops have a RECIPROCAL RELATIONSHIP

4. Resources for understanding exposure: Exposure Triangle

6. Slideshare presentation Sessions College Exposure Wheel Chapter 6: Film Exposure Exposure factors: -subject lighting -lens aperture -shutter speed -film speed -reciprocal relationship -light meter (TTL) vs. Handheld -DX Code -middle gray (18% gray card) -metering patterns (center weighted, multi segment, spot.

7. Exposure Modes: -Manual (M) -Program autoexposure (P) -Aperture-priority autoexposure (A or Av) -Shutter-priority autoexposure (S or Tv) -Subject-program autoexposure portrait, landscapes, close-up, sports P – Program Auto A (Av) – Aperture Priority S (Tv) – Shutter Priority M – Manual (Av, Tv) for Canon

8. “SUNNY 16” Rule Use above chart to determine APERTURE. Use ISO in fractional form to set SHUTTER SPEED. Note: Since it is generally better to overexpose B&W film, use 1/250 second with ISO 400 film.
