Choosing the Best Camera
  • Not a once in a lifetime purchase anymore.
  • Select one which can do the job you want
  • Today and as per your future requirement
  • Some kinds of cameras do.
  • some kinds of things better or more easily
  • e.g., Sports photography vs. Close-up portraits.
  • Price isnt the best indicator.

MEGAPIXEL MYTH
  • How much do you need?
  • Often, cameras are categorized by the no. of
  • Megapixels they can capture .
  • As if that resolution figure is the only measure
  • of the cameras value.
  • This value can be quite misleading.

10
ZOOM OPTICAL AND DIGITAL
  • Optical vs. Digital Zoom
  • An optical zoom uses the optics (lens) of the
    digital
  • camera to move you closer to your subject.
  • A digital zoom simply enlarges the existing
    image
  • digitally. It is not really zoom, in the
    strictest definition
  • of the term.
  • Enlarging the image digitally reduces picture
    quality,
  • and should therefore usually be avoided
  • .
  • Some manufacturers label their lenses with the
    "total
  • zoom" by multiplying the optical with the
    digital.
  • Ignore It.
  • When comparing digital cameras
  • Go for higher optical zoom. Digital zoom can
    always be
  • achieved later in an image editing software.

    Reduction
  • A technology that stabilizes the lens to
  • effectively reduce blur due to camera shake

13
HISTOGRAM
14
METERING
  • How the camera measures the amount of light
  • available to expose a picture
  • Centre-Weighted Readings are taken at
  • various part of the picture, with a special
  • emphasis for the centre.
  • Spot Readings are taken at a specific point.
  • Each camera manufacturer has its own
  • variations (Evaluative Metering)

15
WHITE BALANCE
  • The ability to adjust colours based on white as
  • a reference colour to give as true a white as
  • possible
  • All other colours are corrected accordingly
  • Auto WB (AWB) the camera determines and
  • selects the correct colour temperature for
  • white.

16
WHITE BALANCE
  • Some preset white balance settings are
  • daylight, cloudy, tungsten, or fluorescent.

17
Aperture, Depth of Field, Shutter Speed, ISO,
Noise
  • APERTURE
  • a hole or an opening
  • through which
  • light travels
  • It causes variations in
  • the Depth of Field
  • within the image

  • Shutter Speed
  • Amount of time the
  • picture is exposed
  • Short/Fast shutter speed
  • Long/Slow shutter speed

22
RESULTS OF VARYING SHUTTER SPEED
23
ISO
  • the measure of a digital camera sensors
  • sensitivity to light
  • a higher number indicates higher sensitivity
  • This is usually expressed as a range,
  • e.g. ISO 100 - 1600.
  • A higher sensitivity allows us to take pictures
  • in low light without using flash
  • Higher ISO causes more "noise" than lower
  • ISO

24
Shutter Priority
  • Allows you to decide the shutter speed (e.g.
    fast at 1/500 sec. for stop action photography,
    or slow at 2 sec. for night photography), and the
    camera decides the best aperture.

25
Aperture Priority
  • Allows you to choose the aperture (e.g. large
    at F1.8 for portrait, of small at F16 for
    landscapes).

26
Manual
  • You have complete creative control in
    selecting both the shutter and aperture.

27
Auto
  • All digital cameras usually have an Auto
    mode the camera decides for you the best shutter
    speed/aperture settings.

AUTO
28
Landscape photography
  • Primary function is to allow a large depth of
    field.
  • Landscape mode tells the camera to default to a
  • large Depth of Field (Small Aperture)f16.

29
Portrait Photography
  • This mode is not well suited for full-length
  • portraits or groups of people
  • Portrait mode tells the camera to default to a
  • Small Depth of Field (Large Aperture) f1.8

30
Sports/Action Photography
  • tells the camera to default its settings toward
  • capturing images faster
  • This is done by
  • Increasing Shutter Speed
  • Increasing ISO

31
Night Photography
This preset slows down the shutter speed to
allow a lot of light into the camera. Both
the foreground and background of the image are
properly exposed. very useful in taking
low-light images where you do not want the
background to be black
32
Macro Photography
This setting works with your camera lens to allow
it to focus from a very short distance. Depth
of Field becomes very Small (Large Aperture)
f1.8 Does not have a lot of alternative uses.
33
Why compose your images?
  • Create the picture.
  • Decide what is in and what is left out.
  • Convince the eye to glance at it moment
    longer.
  • Composition" means "Putting Together"

34
  • Rule
  • Of
  • Thirds

35
Rule of thirds
  • The theory is that your photo becomes more
  • balanced and will enable a viewer of the
  • image to interact with it more naturally.
  • Peoples eyes usually go to one of the
  • intersection points most naturally rather than
  • the centre of the shot.
  • It works with this natural way of viewing an
  • image rather than working against it

36
Important to experiment to overcome the natural
tendency to centre everything.
  • But, sometimes you may find situations where
    it's
  • difficult to follow the rule of thirds.
  • If you know why you're doing it -feel free!
  • But when you're first starting out it's a good
    idea
  • to try to follow it whenever you can.

37
Converging composition
  • leads the viewers eye into the depth of the
  • Photo.
  • Usually, centre it and create a symmetrical
  • composition leading to the centre.

38
  • Camera lens filters still have many uses in
    digital photography, and should be an important
    part of any photographer's camera bag....Here
    is the major filters and their function...
  • 1 - Protective Filters
  • UV Filters - Absorbs ultraviolet rays. Gives
    cleaner, sharper pictures with less haze. Also
    serves as a permanent lens protector. Personally,
    i have a UV filter on every lens )

39
EXIF (exchangeable image file)
  • EXIF (exchangeable image file) data is a record
    of what camera settings were used to take a
    photograph.EXIF data stores information like
    camera model, exposure, aperture, ISO, what
    camera mode was used .....To interpret this
    EXIF data, you will need an EXIF viewer. There
    are many ways to go about this. Your image
    processing program should provide that
    functionality within the program.For beginners,
    reading an images EXIF data can be a very useful
    learning tool....

40
Night photography
  • Take a number of shots at different shutter
    speed/aperture combinations.Ensure your LCD
    brightness is set to Normal, not Bright, for a
    truer representation of your recorded image. A
    good aperture to start with is F4.0 or F5.6 (for
    greatest depth of field), and adjust shutter
    speed up or down until you're satisfied with the
    shot.
  • Always bring and use a tripod. It's quite common
    to have exposures of an entire second or more
    during night-time photography.
  • Bring along a flashlight. A pocket
    flashlight is essential when you're doing
    photography at night.

41
Minimalistic photography
  • Minimalistic photos is creating empty spaces in
    the photograph....The eye of the person looking
    at the image cant help but be drawn to the
    element of the image youve taken.... the
    subject!
  • make your subject the strongest point of your
    photo even though it might take up only a small
    part of the overall image....When Im
    attempting to take a show with a minimalist feel
    to it I keep those words in mind.pick subjects
    wisely experiment with color use depth of
    fieldcrop out distractionsZoom In or out...
