File format l.jpg
File Format

  • Refers to the way the computer stores the data

  • More common formats include:

    • JPEG

    • EXIF

    • TIFF

    • RAW


Slide27 l.jpg
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


Slide28 l.jpg
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


Slide29 l.jpg
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


Slide30 l.jpg
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 l.jpg

Rechargeable Batteries

Must Know Info


Why batteries l.jpg
Why Batteries?

Batteries are the soul of photographic equipment


Battery types l.jpg
Battery Types

Rechargeable

  • Nickel-Cadmium (NiCd)

  • Nickel-Metal Hydride (NiMH)

  • LithiumIon (Li-ion)


Nicd batteries l.jpg
NiCd Batteries

  • Memory effect


Nimh batteries l.jpg
NiMH Batteries

  • More widespread


Li ion batteries l.jpg
Li-ion Batteries

  • Proprietary for specific cameras


Milliampere hours mah l.jpg
Milliampere hours (mAh)

  • Refers to how long the battery will last

Why does speed matter l.jpg
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 l.jpg
Zoom Lens

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


Shutter speed l.jpg
Shutter Speed

Slowest shutter speed without a tripod is 1/focal length of lens

(Based on 35mm equivalent)


To avoid the shakes l.jpg
To Avoid The Shakes

Image stabilization:

Using gyro-sensors to detect shakes and compensate

Allows image to be shot at slower shutter speed
