Transcript of Photography Camera Functions
adjusts focal length
smaller focal length the wider the field of view
the higher the focal length the narrower the view.
The delay between you pressing the shutter
release and the shutter activating.
Result of the various calculations the
camera has to make, including focus,
shutter speed, aperture and choosing the
Compact cameras have a longer lag while
SLR cameras have almost no lag.
In Landscape mode, your camera will select the
smallest aperture to maximize depth of field in
the image. Your image will be as sharp as
possible under the conditions in both the
foreground and background. Some cameras also
will apply enhanced color saturation to the
Speed is the name of the game in Sports mode.
Your camera will automatically choose the fastest
shutter speed possible, and also will enable
continuous high-speed shooting if available.
CLOSE-UP (MACRO) MODE
Macro shots can be an
interesting window into a
smaller world that we
don’t usually notice.
Macro mode allows you to focus on objects
extremely close up, though your zoom range may
Successful night photography requires a slow shutter
speed for a long exposure without flash. The exposure
may last several seconds, so use a tripod when
shooting in this mode or place your camera on a solid
Also, be aware that most digital sensors
generate image noise during exposures of more than a
NIGHT PORTRAIT MODE
For flattering portraits in dark conditions, you
want a combination of flash with a long
exposure to pick up ambient background lights.
In this mode, the flash fires to freeze the action
of your subject amid the lengthened exposure.
Beach and snow Mode
Flash Off Mode

Functions of the Camera
JPEG (.JPG) is the most common. Makes the
smallest file size. Uses compression and creates a lossy image. Lowest quality.
Tiff is available on some cameras no compression like jpeg.
Raw for the most serious photo editor but makes the largest files.
This mode emphasizes the subject by deemphasizing
the background. The camera selects
the widest possible aperture setting to minimize
depth of field for a softened background. The
flash usually will switch to its red-eye reduction
setting when shooting in this mode. Remember to
focus on your subject’s eyes.
(Hold the button halfway before the shot)
Photography is the "capturing of light"
Light enters the lens, and strikes the sensor.
The sensor is then EXPOSED to light!
But, how much light has to hit the sensor to make a good image?
...and how can I control it?
This is where the three brothers come in...
Sets the camera's sensitivity to light
Higher numbers increase the sensitivity to light
More noise at higher numbers
Use the lowest number possible that will give the best exposure.
ISO 100 or 200 for sunlight
ISO 400 or 800 for low light conditions
ISO 1600+ will shoot just about anywhere but more noise possible.
Lower ISO (200)
Higher ISO (1600)
The shutter is how fast the shutter curtain opens to EXPOSE the sensor to light.
The higher the fraction, the faster the shutter.
1/1000 (very fast)
The aperture relates to the opening in the lens.
Also called the iris
IMPORTANT: Change opening using F-Stop settings.
Lower numbers=large opening
More open, more that sensor is EXPOSED to light
Higher numbers=smaller opening
Less open, less that sensor is EXPOSED to light
All three are different ways to EXPOSE the sensor to more or less light.
Each one has its strengths and weaknesses.
*Good for action and movement*
Good for blurring out backgrounds.
You heard it.
Now repeat it.
