CHARACTERISTICS OF PROGRAMMODE
●Aperture and shutter speed are set by the camera, but can be
shifted using the control dial, with the exposure staying the same
●Unlocks some other settings in your camera that gives you
more control over the final image : ISO setting, white balance,
exposure compensation
●Great for quickly getting a photograph without having to think
too hard about settings
CHARACTERISTICS OF TVMODE
● TV means time value
●Shutter priority: set the shutter speed and calculates the
matching aperture
●To photograph moving subjects (sporting action). A faster
shutter speed will freeze the motion
●To capture movement as a blur of a waterfall, choose a slower
shutter speed
CHARACTERISTICS OF AVMODE
●AV means aperture value
●Manually control the aperture while the camera sets the
matching shutter speed
●Particularly useful to control a stationary object where you
don’t need to control the shutter speed
●Choosing a larger aperture (f/stop) means the lens will get
smaller and it will let less light in so a larger depth of field
(more of the area in focus), but your camera will choose a
faster shutter speed and vice versa
CHARACTERISTICS OF MANUAL
MODE
●Fullcontrol over camera settings such: shutter speed, aperture,
ISO, white balance and exposure compensation
●Gives you the flexibility to set your shots the way you want them
to be
●Can result in creative and non-traditional exposures
CHARACTERISTICS OF PORTRAITMODE
●An automatic mode with emphasis on settings for a perfect
portrait shot.
●The ability of the camera to detect if there are faces in the
image and to ensure they are all in focus
●Sets a wide aperture of the lens so that the background behind
your subject is softly focused (shallow depth of field)
CHARACTERISTICS OF LANDSCAPE
MODE
●Narrowsthe aperture, so both the subject and background
stay sharp (deep depth of field)
●Foreground, middle ground, and background are all in focus
●Exposure compensation for entire frame
CHARACTERISTICS OF MACROMODE
●An automatic mode with emphasis on settings for close-up
photography
●Commonly used to photographing flowers, insects and other
small items
●Somecameras may be able to focus when the lens is less than
an inch away from the subject
●Creates a very shallow depth of field
CHARACTERISTICS OF ACTION/SPORTS
MODE
●Representedby an icon of a sprinter, this is perfect for taking
pictures of moving objects
●Also good for shooting children or pets in action
●Can give you higher shutter speeds to stop action, along with
a smaller aperture so that more of the action will be in focus
CHARACTERISTICS OF NIGHTPORTRAIT
MODE
●Usually symbolized by a figure against a dark sky with a star
●Fires the flash to illuminate a nearby subject and then holds the
shutter open long enough for the background to be exposed
UNDERSTANDING EXPOSURE
●THE WINDOWEXAMPLE
●Imagine your camera is like a window with shutters that open and close.
●Aperture is the size of the window. If it’s bigger more light gets through and the
room is brighter.
●Shutter Speed is the amount of time that the shutters of the window are open. The
longer you leave them open the more that comes in.
●Now imagine that you’re inside the room and are wearing sunglasses. Your eyes
become desensitized to the light that comes in (it’s like a low ISO)
●.There are a number of ways of increasing the amount of light in the room (You
could increase the time that the shutters are open (decrease shutter speed), you
could increase the size of the window (increase aperture) or you could take off your
sunglasses (make the ISO larger)
26.
APERTURE
●The aperture ofa lens is the diameter of the lens opening
●The larger the diameter of the aperture, the more light reaches
the film / image sensor
●Aperture is expressed as F-stop, e.g. F2.8 or f/2.8
●The smaller the F-stop number (or f/value), the larger the lens
opening (aperture) (inverse relationship)
●Controls depth of field
Depth of FieldEXERCISE
●Pick a partner
●Stand away from your partner
●Take a photograph of their face only with your lens unzoomed
● Zoom in and shoot but only fill the frame with their entire face
again
●See the difference in depth of field
SHUTTER SPEED
●Shutter speedis the amount of time that the shutter is open
●Shutter speed is measured in seconds – or in most cases
fractions of seconds
●It is not in isolation from the other two elements of the Exposure
Triangle (aperture and ISO)
●Long shutter causes blur and fast shutter freezes motion
