File Format
Refers to the way the computer stores the data More common formats include: JPEG EXIF TIFF RAW
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
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
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
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
Rechargeable Batteries Must Know Info
Why Batteries? Batteries are the soul of photographic equipment
Battery Types Rechargeable Nickel-Cadmium (NiCd) Nickel-Metal Hydride (NiMH) Lithium Ion (Li-ion)
NiCd Batteries  Memory effect
NiMH Batteries  More widespread
Li-ion Batteries  Proprietary for specific cameras
Milliampere hours (mAh)  Refers to how long the battery will last

Its About The Speed
Lenses
Why does speed matter? The more light a lens gathers, the less time it needs to hold the shutter open for proper exposure
Zoom Lens Maximum zoom is hard to hold camera steady for a sharp picture
Shutter Speed Slowest shutter speed without a tripod is 1/focal length of lens (Based on 35mm equivalent)
To Avoid The Shakes Image stabilization: Using gyro-sensors to detect shakes and compensate Allows image to be shot at slower shutter speed
