  1. EXPOSURE

  2. EXPOSURE - Process by which light is gathered by the camera lens to record a latent image onto the film DEVC 151: EXPOSURE

  3. Considerations: 1) Lighting condition a) Bright Sun (BS) – subject casts distinct shadow DEVC 151: EXPOSURE

  4. Considerations: 1) Lighting condition b) Hazy Sun (HS) – subject casts soft shadow DEVC 151: EXPOSURE

  5. Considerations: 1) Lighting condition c) Cloudy Bright (CB) – subject has/ lesser shadow DEVC 151: EXPOSURE

  6. Considerations: 1) Lighting condition d) Heavy Overcast (HO) – has no shadow, about to rain (or raining) DEVC 151: EXPOSURE

  7. Considerations: 1) Lighting condition e) Open Shade (OS) – subject under any lighting condition but under a shade DEVC 151: EXPOSURE

  8. Considerations: 2) Shutter Speed and Aperture Combination Bracketing – shooting same subjects with different f-stops and shutter speeds DEVC 151: EXPOSURE

  9. Considerations: 3) Focus DEVC 151: EXPOSURE

  10. Considerations: 4) Type of Film Film – a roll or sheet of thin, flexible, transparent material cover on one side with light –sensitive silver salts. DEVC 151: EXPOSURE

  11. Considerations: 4) Type of Film TYPES OF FILM: 1) Based on Film Speed – degree of light sensitivity of the film - ranges from 25 – 3200 ASA DEVC 151: EXPOSURE

  12. Considerations: 4) Type of Film TYPES OF FILM: - Higher ASA, the amount of light needed to produce a normal image decreases - The higher the film speed, the more sensitive the film to light DEVC 151: EXPOSURE

  13. Considerations: 4) Type of Film TYPES OF FILM: 1) ASA – N. America, Australia, Asia 2) DeutcheIndustrieNorme (DIN) – Continental Europe 3) International Standards Organization (ISO) – two film speed figures (ASA/DIN) 4) GOST - Russia DEVC 151: EXPOSURE

  14. Considerations: 4) Type of Film TYPES OF FILM: a) Slow-speed film (ASA 25-ASA 50) – excellent for brightly-lighted scenes - Has a rich gradation of tones and virtually no grain DEVC 151: EXPOSURE

  15. Considerations: 4) Type of Film TYPES OF FILM: b) Medium-speed film (ASA 100 – ASA 200) – general-purpose film suitable to most subjects and lighting conditions - Versatile DEVC 151: EXPOSURE

  16. Considerations: 4) Type of Film TYPES OF FILM: c) Fast Film (ASA 400 – ASA 500) – best for taking pictures in low light situations like campfire settings or candlelit scenes or when fast action demands high shutter speeds DEVC 151: EXPOSURE

  17. Considerations: 4) Type of Film TYPES OF FILM: d) Super Fast Film (ASA 1000 – ASA 3000) – can be used to take pictures in extremely dim light – as little as that given by a single candle DEVC 151: EXPOSURE

  18. Considerations: 4) Type of Film TYPES OF FILM: DEVC 151: EXPOSURE

  19. KINDS of EXPOSURE • Underexposed – low light Dark (photo) Brighter (negative) • Underexposed – low light Brighter (photo) Dark (negative) DEVC 151: EXPOSURE

  20. KINDS of EXPOSURE DEVC 151: EXPOSURE

  21. Determining Proper Exposure Using the Daylight Exposure Guide - A manual exposure guide for outdoor picture taking for particular film and its film speed as provided by its manufacturer DEVC 151: EXPOSURE

  22. Determining Proper Exposure Using the Daylight Exposure Guide DEVC 151: EXPOSURE

  23. Determining Proper Exposure Using the Daylight Exposure Guide The Principle is: • Bigger aperture, faster shutter speed • Smaller aperture, slower shutter speed DEVC 151: EXPOSURE

  24. Determining Proper Exposure Using the Daylight Exposure Guide * As the light gets DIMMER, the aperture should be BIGGER to admit MORE light. DEVC 151: EXPOSURE
