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
