26 File Format Refers to the way the computer stores the data More common formats include:  JPEG  EXIF  TIFF  RAW

27 JPEG Stands for Joint Photography Experts Group Most widely used format Biggest advantage - can compress image data Do not edit JPEG images in photo-editing programs to minimize data loss

28 EXIF Stands for Exchange Image File Format Used by many digicams Is a variation of the JPEG format Stores extra data as metadata with the image file Metadata stores shutter speed, aperture, and other capture settings

29 TIFF Stands for Tagged Image File Format Is the choice for bringing images into publishing programs Does not compress as much as JPEG Choose when picture quality is more important than file size

30 RAW Simply means raw Used by high-resolution digicams Does not include any in-camera processing features Provides a truer version of the scene in front of the camera Large file size Back

31 Rechargeable Batteries Must Know Info

32 Why Batteries? Batteries are the soul of photographic equipment

33 Battery Types Rechargeable  Nickel-Cadmium (NiCd)  Nickel-Metal Hydride (NiMH)  Lithium Ion (Li-ion)

34 NiCd Batteries  Memory effect

35 NiMH Batteries  More widespread

36 Li-ion Batteries  Proprietary for specific cameras

37 Milliampere hours (mAh)  Refers to how long the battery will last Back

38 Its About The Speed Lenses

39 Why does speed matter? The more light a lens gathers, the less time it needs to hold the shutter open for proper exposure

40 Zoom Lens Maximum zoom is hard to hold camera steady for a sharp picture

41 Shutter Speed Slowest shutter speed without a tripod is 1/focal length of lens (Based on 35mm equivalent)

42 To Avoid The Shakes Image stabilization: Using gyro-sensors to detect shakes and compensate Allows image to be shot at slower shutter speed
