File Formats
 What  are formats? (native vs standard)
 Controls the file type and the size of the
 All cameras save in JPEG
 Some also save in TIFF and RAW
 Choose   the resolution within the file
  formats available on your camera
 Know your pictures destination: WEB or
  print / Snapshot or 8x10
 Resolution determines the image size
  and the amount of picture information
 Why not take all your images at the
 highest resolution?
   The higher the res the larger the file size
   and the fewer images you can fit on a card
   The higher the res the longer it takes to
   record the image on the card
   Law of diminishing returns: if you are
   sending these via email to be seen on the
   monitor you will be throwing pixels away
 Two   methods for changing settings
   Most commonly used features are usually
   buttons on the camera
   Most settings are accessed using a menu
   Some cameras allow you to save settings
   Manual describes the options
 Autofocus  works in most situations
 Set the focus by moving the camera
  and reframe to shoot your picture
 Manual focus
    Measure the distance
    Viewfinder not always reliable
 Normal  settings allow you to get about
  10-12 inches from the subject
 Use Macro focus to get closer (you will
  need to set this)
 “Letting in Light”
 Shutter priority: Set the speed and let
  the camera auto expose
 Aperture Priority: set f-stop and let the
  camera choose the shutter speed
 Manual Exposure: setting both the
  shutter speed and the f-stop
 For some control use Exposure
 Slightly lighter ore darker to tone down
  glare or enhance highlights
 Expressed in positive and negative
    Positive: brighter
    Negative: darker
White Balance
 Artificial   light (indoors)
     You can compensate in Photoshop
     Or you can keep it from causing a problem
 Set   for:
     Cloudy outdoors
     Bright outdoors
White Balance
 Most cameras have an auto setting that
  determine the best setting
 No set rules: so experiment
 Optical  vs Digital
 Optical zoom uses the lens
 Digital zoom uses the “computer” in the
  camera the same as image editing
 Most  cameras automatically detect
  when the flash is necessary
 Solid light indicates the flash is ready
 After the shot there is a delay while the
  flash powers up again
 Most flash light is limited to 10-15 feet
 Reducing   Red Eye
   Human eye’s iris reflects the flash as a
   bright red
   Most cameras offer a red-eye reduction
   Flash will fire twice to close the iris
   Image editing software can reduce this
 Fillflash will bring out the darker areas
  of an image
 When set to fill flash the camera will
  reduce the amount of flash
 Some   situations may contain reduced
  light but a flash may be inappropriate
 Most digital cameras allow you to
  suppress the flash
 Without the flash the shutter speed may
  be so slow that the image is blurred
 Use a tripod
Shooting at Night
 At night the flash will illuminate the
  subject, but the shutter speed may be
  too fast to capture outside the flash
 Some cameras offer a night flash or
  slow shutter setting
 Shutter stays open and captures the
  area around the flash
Flash Correction
 Sometimes    the flash is too light or dark
  or too glaring
 Some cameras offer a flash correction
 Set the flash to be brighter or darker
Self-Timer / Remote Control
 Some    cameras offer a remote control
  option which allows you to press a
  button and waits 10-20 second for you
  to get in the shot
 This can also be useful if you are taking
  a tripod shot and you don’t want to
  shake the camera
