  1. Basic Camera Functions Class 2 – DACC Basic Photography I Class

  2. Traditional Camera - Film Digital Camera – CCD and memory storage device Basic Camera Functions

  3. Advanced Modes • P – Program Mode • Tv – Shutter Speed Priority • Av – Aperture Priority • M – Both Shutter and Aperture set manually • A-DEP – An aperture priority where camera sets f-stop according to the subject

  4. Program Mode • Camera selects both the Shutter and Aperture for you • Will also let camera turn on the flash if it thinks it’s needed • User chooses the ISO

  5. Camera Controls – Shutter Speeds • In Shutter Speeds – Amount of time for the exposure. Usually in fractions of a second • Focal Plane Shutters has a “flash Sync” shutter speed

  6. Shutter Speeds • 1 sec. – ½ sec. – ¼ sec. – 1/8 sec. – 1/15 sec. – 1/30 sec. – 1/60 sec. – 1/125 sec. – 1/250 sec. – 1/500 sec. – 1/1000 sec. • Digital Cameras have intermediate shutter speeds • Ability to hand-hold a cameraLens mm = shutter speed

  7. Stopping action

  8. Let’s Look at Shutter Controls

  9. Focal Lengths 18mm 55mm 150mm 300mm

  10. Focal Length Changes Perspective 300mm 200mm 100mm 50mm 20mm 10mm

  11. Aperture controls Depth of Field • F- stops - f-2.8 – f-4.0 – f-5.6 – f-8.0 – f-11 – f-16f-22 – f-32 • The larger the number – the smaller the aperture • The smaller the aperture – the greater the depth of field • The smaller the aperture, more exposure time or higher ISO is needed

  12. Depth of Field Exp – 8 sec. – F32 – 100 ISO Exp – 1/6 sec. – F4.0 – 100 ISO

  13. Selective Focus

  14. Camera Control - Focus • Manual Focus • Selecting an Auto Focus Point • Focus Lock

  15. Let’s Look at f-stops, depth of field and focus control

  16. Film Speed • ASA – ISO • Lower speed needs more light – higher quality image • Higher speeds require less light – stops action – less image quality • Larger formats provides higher quality photos

  17. Grain / Noise • Higher speed /low light conditions = photos with electronic “Noise” • Changing the ISO of your camera • ISO 100 – ISO 3200+ • Sunny 16 Rule - Bright Sunlight ExposureAperture = f-16Shutter Speed = ISO of Film

  18. Metering your Image • Types of Light MetersIncidentReflective • What is the Meter Looking For • 18% Gray

  19. Exposure Compensation • Fooling Automation

  20. Situations that can fool your meter

  21. Let’s Look at ISO Speed Controls And Exposure Compensation

  22. Traditional Cameras use lower power batteries that sometimes last for 6 months to a year. Digital thrives on Batteries Previews Built in Flashes Auto focus Automatic shutdown 2 hour max for most cameras Batteries

  23. H-T-D-C-S • Tripods • Monopods • Tripod Brackets • Hand-holding tricks • Self timers and cable releases

  24. Exterior Camera Buttons and Menus
