### Transcript

• 1. Photography A small sip from a firehose!
• 2. Digital Single Lens Reflex Camera (DSLR Camera) Aperture Light Sensor Shutter Mirror
• 3. 3 Pillars to Proper Exposure 1. Shutter Speed 2. Aperture 3. ISO
• 4. ISO Aperture Shutter Speed Proper Exposure
• 5. Shutter Speed &#x2022; The amount of time the shutter (curtain) is open to allow light to expose the sensor (or film). &#x2013; Expressed in seconds or fractions or a second &#x2022; For example 1/400 sec. &#x2013; Doubling or halving = 1 full stop of light &#x2022; For example, 1/800 is 1 stop down from 1/400 &#x2022; The faster the shutter speed, the less light is allowed to hit the sensor.
• 6. Aperture &#x2022; The opening in the lens that controls the amount of light that enters the body of the camera. &#x2013; Expressed in f numbers &#x2022; For example f5.6 &#x2013; The larger the number, the smaller the opening &#x2022; F22 is a smaller hole than f5.6 &#x2022; Each &#x201C;stop&#x201D; is represents &#xBD; the light (or double) &#x2013; Full stops are: f 1.4, 2, 2.8, 4, 5.6, 8, 11, 16, 22, 32
• 7. ISO &#x2022; The expression of the sensor&#x2019;s (or film&#x2019;s) sensitivity to light. &#x2013; Expressed as ISO &#x2022; For example ISO 400 &#x2013; or 400 ISO. &#x2013; Doubling (or halving) equals 1 full stop of light &#x2022; For example ISO 200 is 1 stop down from ISO 400.
• 8. Baseline Exposure Sample We&#x2019;ll assume that this is the proper exposure for the following exercise. Shutter- 1/500 Aperture- f8 ISO400
• 9. Baseline Exposure Sample These settings will yield exactly the same exposure! Shutter- 1/500 Aperture- f8 ISO400 = Shutter- 1/1000 Aperture- f8 ISO800
• 10. Baseline Exposure Sample These settings will yield exactly the same exposure! Shutter- 1/500 Aperture- f8 ISO400 = Shutter- 1/1000 Aperture- f5.6 ISO400
• 11. Baseline Exposure Sample These settings will yield exactly the same exposure! Shutter- 1/500 Aperture- f8 ISO400 = Shutter- 1/2000 Aperture- f4 ISO400
• 12. Baseline Exposure Sample These settings will yield exactly the same exposure! Shutter- 1/500 Aperture- f8 ISO400 = Shutter- 1/500 Aperture- f5.6 ISO200
• 13. Baseline Exposure Sample These settings will yield exactly the same exposure! Shutter- 1/500 Aperture- f8 ISO400 = ShutterAperture- f11 ISO-
• 14. Baseline Exposure Sample These settings will yield exactly the same exposure! Shutter- 1/500 Aperture- f8 ISO400 = Shutter- 1/250 ApertureISO-
• 15. Baseline Exposure Sample These settings will yield exactly the same exposure! Shutter- 1/500 Aperture- f8 ISO400 = ShutterAperture- f11 ISO-
• 16. Baseline Exposure Sample These settings will yield exactly the same exposure! Shutter- 1/500 Aperture- f8 ISO400 = ShutterApertureISO1600
• 17. But why do I care?
• 18. Shutter Speed &#x2022; Slow shutter speeds cause blur! &#x2013; Hand-hold 1/focal length &#x2022; Some lenses may have Vibration Reduction (VR) for Nikon and Image Stabilization (IS) for Canon. This is a useful too, but I don&#x2019;t count on it!
• 19. 1/80 f4.5 ISO 400 Focal Length 135mm
• 20. Shutter Speed &#x2022; Slow shutters can be used for creativity as well. 5.8sec (tripod) f4.5 ISO 640 Focal Length 24mm
• 21. Shutter Speed &#x2022; Fast shutter speeds freeze action! &#x2013; Great for sports or creative shots &#x2022; Normally require a lot of light or&#x2026;.what? 1/2500 f5.6 ISO 800 Focal Length 280mm
• 22. Shutter Speed &#x2022; Fast shutter speeds freeze action! 1/4000 f8 ISO 800 Focal Length 210mm
• 23. Aperture (Depth of Field) &#x2022; Wide open apertures (large aperture, small fstop) &#x2013; Very shallow Depth of Field (DOF) &#x2022; Small area of the subject will be in focus and background/foreground will be blurred
• 24. 1/200 f3.5 ISO 4000 Focal Length 105mm (fixed macro)
• 25. Aperture (Depth of Field) &#x2022; Ultra Wide open apertures (large aperture, small fstop) &#x2013; Extremely shallow Depth of Field (DOF) &#x2013; Subject is a feature within the subject (single eye for example)
• 26. 1/6400 f1.4 ISO 400 Focal Length 105mm (fixed macro)
• 27. Aperture (Depth of Field) &#x2022; Stopped down apertures (small aperture, larger fstop) &#x2013; Wide Depth of Field (DOF) &#x2022; Larger area of the subject will be in focus as will increasing amount of background/foreground.
• 28. Aperture (creative use)
• 29. 1/3200 f14 ISO 4000 Focal Length 105mm (fixed macro)
• 30. Aperture &#x2022;Intentional use of DOF &#x2013; show/hide as you desire This table wasn&#x2019;t ready to be photographed *as seen in Ceremony Magazine 1/400 f5 ISO 800 Focal Length 200mm
• 31. Aperture Intentional use of DOF &#x2013; makes focusing easier 1/4000 f8 ISO 800 Focal Length 500mm (pacing)
• 32. ISO Lower ISO = Better quality, lower noise 1/2500 f2.8 ISO 800 Focal Length 200mm
• 33. ISO Higher ISO = Lower quality, Higher noise 1/50 f2.8 ISO 25,600 Focal Length 98mm
• 34. ISO Higher ISO - Sometimes you just HAVE to! 1/30 f2.8 ISO 25,600 Focal Length 86mm
• 35. Light &#x2022; Not all light is created equal &#x2013; Window light &#x2013; Direct sunlight &#x2013; Open Shade &#x2013; Flash (on-camera, off-camera, studio) &#x2013; Bulbs &#x2013; Reflected &#x2013; Diffused
• 36. Light &#x2022; The BIGGER the source, the better! &#x2013; The sun is not a big source. &#x2013; A large panel close to the subject is.
• 37. Diffused &#x2022; Beautiful light
• 38. Look at Eyes for Lighting
• 39. On Camera Flash generally not preferred &#x2022;Very small source &#x2013; small catch light &#x2022;Harsh shadows &#x2022;Good for snapshots at the beach or in direct sunlight situations. &#x2022;Force your camera flash on.
• 40. Bounced On Camera Flash &#x2026;better
• 41. Off Camera Flash
• 42. Off Camera Flash
• 43. Window Considered by many to be the best!
• 44. Studio (and paper)
• 45. Reflector One of my favorites for control
• 46. Composition &#x2022; We see life from somewhere around 5-6&#x2019;. &#x2013; Show the viewer something different than that. &#x2013; They won&#x2019;t know why the like it, they just will. &#x2013; Get down on the ground. &#x2013; Climb up in trees or on chairs. &#x2013; Put the subject down on the ground.
• 47. Rule of Thirds &#x2022; Says &#x201C;Don&#x2019;t center your subject.
• 48. Rule of Thirds in Practice
• 49. Dare to be different Take 1 normal &amp; 1 &#x201C;risky&#x201D;
• 50. Rules are Made to be Broken
• 51. Low Point of View
• 52. High Point of View
