file format
File Format
  • Refers to the way the computer stores the data
  • More common formats include:
    • JPEG
    • EXIF
    • TIFF
    • RAW
slide27
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
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
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
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

why batteries
Why Batteries?

Batteries are the soul of photographic equipment

battery types
Battery Types

Rechargeable

  • Nickel-Cadmium (NiCd)
  • Nickel-Metal Hydride (NiMH)
  • LithiumIon (Li-ion)
nicd batteries
NiCd Batteries
  • Memory effect
nimh batteries
NiMH Batteries
  • More widespread
li ion batteries
Li-ion Batteries
  • Proprietary for specific cameras
milliampere hours mah
Milliampere hours (mAh)
  • Refers to how long the battery will last

why does speed matter
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
Zoom Lens

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

shutter speed
Shutter Speed

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

(Based on 35mm equivalent)

to avoid the shakes
To Avoid The Shakes

Image stabilization:

Using gyro-sensors to detect shakes and compensate

Allows image to be shot at slower shutter speed
