2 The Numbers  Lens Function  MM  F Stop  Camera Body Function  Shutter Speed  ISO Dan Garrett 11/2012

3 MM  MM is the unit of measure for a lens focal length. The distance from the lens focal point to the sensor. Dan Garrett 11/2012

4 F-Stop  How much light is allowed to contact the sensor.  Affects:  Exposure  Focus / Depth of Field Dan Garrett 11/2012

5 Shutter Speed  The length of time the light is allowed to contact the sensor.  Affects  Exposure  Motion Dan Garrett 11/2012

6 ISO  How sensitive the sensor is to light  Affects  Exposure  Image Quality / Noise 100, 200, 400, 800, 1600, 3200, 6400, 12800 Most Light Least Light Dan Garrett 11/2012

7 Final Picture ExposureMotionDepth of FieldNoiseSharpnessComposition ISO MM Shutter Speed f-stop Dan Garrett 11/2012

8 Focus  Manual  Automatic  Continuous Automatic  Image Stabilization  Lens  Camera  AF Mode Selector Single Point, Dynamic Area, or Auto Area Dan Garrett 11/2012

9 Lens Types  Prime  Zoom  Standard  Wide Angle  Telephoto  Macro  Tilt  Teleconverter Dan Garrett 11/2012

10 Common Filters  Neutral Density  Graduated Neutral Density  Circular Polarizer (DSLR)  UV, Clear, Skylight  Many More  Sized to match lens. Dan Garrett 11/2012

11 Changing Lens  Protect from contamination  Use lens caps  Camera pointed down  Align Marks Dan Garrett 11/2012

12 Lens Hood  Blocks side light, glare spots  Matched to lens  Physical protection Dan Garrett 11/2012

13 Lens Cleaning  Lens Pen  Cloth  Cleaner Solution  very sparingly  Apply to cloth, not lens  Blower  Never use compressed air  Hold so dust falls out Dan Garrett 11/2012
