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

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
