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
