2. Manual mode
 What is Manual Mode on a DLSR camera?
 Manual mode is an exposure mode similar to Aperture Priority and Shutter Priority, but unlike those semi-automatic options, you have to
set both the aperture and the shutter speed by hand.
 What is the manual setting on a camera?
 The camera does this for you in the automatic and semi-automatic exposure modes, tweaking the aperture, shutter speed or both in order
to maintain a consistent exposure. However, the fact that the aperture and shutter speed settings stay locked in with Manual mode is its
chief advantage.
 Characteristics of Manual Mode
 Full control over camera such: shutter speed, Aperture, ISO, white balance and compensation
 Gives you flexibility to set your shots the way you want them to be
 Can result to creative and non-traditional exposures

3. Shutter Speed
 Shutter speed is 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 other two elements of the exposure Training(Aperture and ISO)
 Long shutter causes blue and fast shutter freezes motion

4. Aperture
 About Aperture?
 In optics, an aperture is a hole or an opening through
which light travels. More specifically, the aperture and
focal length of an optical system determine the cone
angle of a bundle of rays that come to a focus in the
image plane.
 The aperture is the opening at the rear of the lens that
determines how much light travels through the lens and
falls on the image sensor.
 The aperture controls the amount of light that reaches a
digital camera sensor. An aperture acts much like the pupil
of an eye. It opens wider as light decreases to let in more
available light. It gets smaller when light increases to
reduce the amount of light entering the eye.
This is an example of Aperture this shows the
sizes of the holes opening though the
amount of light that travels through it.

5. ISO
 In very basic terms, ISO is the level of sensitivity of your
camera to available light. The lower the ISO number, the less
sensitive it is to the light, while a higher ISO number
increases the sensitivity of your camera.
 ISO speed affects the shutter speed / aperture combinations
you can use to obtain correct exposure.
 When you boost the sensitivity of your image sensor by
selecting a higher ISO, the image sensor is now able to
record a fainter light signal. However, it is also true now that
it will record fainter noise, where noise is any signal that is
not attributed to the light from your subject.

6. Automatic Mode
 What is automatic Mode on a DLSR
camera?
 Auto mode tells your camera to use it’s
best judgement to select shutter speed,
aperture, ISO, white balance, focus and
flash to take the best shot that it can
 This mode will give you nice results in
many shooting conditions, however you
need to keep in mind that you’re not
telling your camera any extra information
about the type of shot you’re taking so it
will be ‘guessing’ as to what you want.

7. Automatic Mode settings
•Action or sports modes increase ISO and uses a faster shutter speed to capture action.
•Landscape modes use a small aperture to gain depth of field. Flash may be deactivated.
•Text mode increases in-camera sharpening to allow to photograph texts.
•Portrait mode widens the aperture to throw the background out of focus. The camera may
recognize and focus on a human face.
•Water modes, depending on what the mode is designed to do, will either widen the aperture
and increase the shutter speed for an action shot or shrink the aperture and slow down the
shutter speed to show the motion of the water.
•Snow modes compensate for the misinformation the white snow gives the light meter and
increases exposure in order to properly photograph subjects.
•Natural light or night snapshot modes attempt to raise the ISO and use a very wide aperture
in order to take a photograph using the limited natural light, rather than a flash. In Fujifilm
cameras, a variation of this mode takes two pictures: one with flash and other without it.
•High sensivity modes use the highest ISO available, albeit at lower resolutions in order to
cope with noise.
•Macro or close-up modes tend to direct the camera's focus to be nearer the camera. It may
shrink the aperture and restrict the camera to wide-angle in
These are a few of different types of automatic modes
you will find on a camera.
