This document provides an introduction to digital photography, including an overview of digital cameras and their advantages over film cameras. It discusses basic camera components like sensors and storage as well as different types of digital cameras. It also covers lenses, megapixels, image stabilization, and basic camera controls like aperture, shutter speed, and ISO. The goal is to educate newcomers to digital photography about selecting and using a digital camera.

3. Digital Photography
•is a form of photography that uses digital
technology to make images of subjects.
•digital photographs can be
displayed, printed, stored, manipulated, t
ransmitted, and archived using digital
and computer techniques,

5. Advantages of Consumer
Digital Cameras over
Film
•Instant review of pictures
• Minimal ongoing costs
• Photos may be copied from one digital
medium to another without
any degradation
• Pictures do not need to be scanned before
viewing them on a
computer
• Ability to print photos using a computer and

6. Advantages of Consumer
Digital Cameras over Film
•Ability to capture and store hundreds of
photographs on the same media device
• Many digital cameras now include an AV-
out connector (and cable) to allow the
reviewing of photographs to an audience
using a television
• Anti-shake functionality (increasingly
common in inexpensive cameras) allow
taking sharper hand-held pictures where
previously a tripod was required
• Ability to change ISO speed settings more

7. Advantages of Consumer
Digital Cameras over Film
•Ability to use the same device to
capture video as well as still images.
•Ability to convert the same photo from
color to sepia to black & white

11. Types of Digital Cameras

12. Types of Digital Cameras
Point and Shoot
usually have fewer controls than other
digital cameras but many are also
small, bordering on tiny. With a camera
that fits into your pocket, you're more
likely to have it when you need it.

13. Types of Digital Cameras
Camera Phones
The fastest selling point and shoot digital
cameras are those built into camera phones.
Camera phone quality is improving rapidly
with 8 Megapixel models already available in
some parts of the world. In time these
cameras may present real competition to point
and shoot cameras.

15. Types of Digital Cameras
Prosumer/ Bridge Camera
High-end fixed lens cameras usually have a
zoom lens and many of the exposure and
focus controls found on SLR cameras. Fixed
lens cameras often have great zoom lenses
and capture large images.

16. Types of Digital Cameras
DSLR- (digital single-lens reflex), these cameras
are expensive but have certain advantages over
other camera types:
• You can change lenses.
• You see the scene through the lens so what you
see is what you get.
• You can select from a large variety of
accessories, including powerful flash units.

17. Non-DSLR vs DSLR
1. Price: 5,000-20,000 30,000-150,000
2. SIZE and WEIGHT:
3. Zoom Digital zoom Mechanical Zoom
4. Sensor 6.1mm x 4.6mm 23.6mmx15.8mm

19. Non-DSLR vs DSLR
Non-DSLR cameras DSLR cameras allow the
differ in that they use a photographer to see the
viewfinder or display subject or scene through the
screen to help the optical lens. What you see is
photographer frame the basically what you get in the
subject that is being photo.

22. Understanding the Pixel
Pixel, or pel , (picture element) is a
single point (dot) in a graphic image.
The number of pixels n for a given
maximum resolution
(w horizontal pixels by h vertical pixels)
is the product n = w × h.

23. PIXEL

24. Understanding the Pixel
Megapixel:
Mega=million
Pixel=dot
e.g.
Nikon D60 = 10megapixel
3,648 x 2,736 = 9,980,928
w x h = n

27. Buying Digital Camera
Lens is an optical
device with perfect or
approximate axial
symmetry which
transmits and
refracts
light, converging or
diverging the light.

28. LENS

29. Buying Digital Camera
Kinds of Lenses
1. Kit Lens 18-55mm
2. Prime lens 35mm
3. Zoom lens 55mm-200mm

30. Buying a Digital Camera
Image Stabilization
is a family of techniques used to
increase the stability of an image.
Nikon (Vibration Reduction/VR)
Canon (Image Stabilization/IS)
Panasonic/Leica (MegaOIS)
Sony (Super Steady Shot)
Sigma (Optical Stabilization)
Pentax (Shake Reduction)

the left shows the
path the light
travels from the
object to the
sensor.

35. APERTURE
The aperture sits inside the lens and controls how much
light passes through the lens and onto the sensor.
Knowing how the aperture affects the photograph is one
of the most important parts of photography — it affects
the amount of light, depth of field, lens speed, sharpness
and vignetting among other things.

36. APPERTURE

37. SHUTTER
The shutter is what controls how long the sensor is exposed
to the light. The longer the shutter is open the more light can
be captured by the sensor. A fast shutter speed will result in
“freezing” a moving object and a slow shutter speed will let
you capture the motion of a moving object.

38. SHUTTER
SLOW SHUTTER SPEED FAST SHUTTER SPEED

39. ISO
 The ISO speed (the name comes from the
International Organization for Standardization) is a
measure of the film speed, or its sensitivity to light.
 A low ISO speed requires a longer exposure and is
referred to as slow, a high ISO speed requires less time
to give the same exposure and is therefore referred to
as fast.
 ISO measures the sensitivity of the image
sensor

40. ISO
Auto ISO
Fortunately most of the time you don’t need
to worry about selecting the correct ISO. Most
cameras have an “Auto ISO” setting. With
Auto ISO, the camera will look at the amount
of light in the scene and change the ISO
appropriately so that the shutter speed
doesn’t get too slow.

41. ISO Value
If you choose to use a manual ISO, what values should you
use?
ISO 50-100. Suitable for bright light (like outdoors on a
sunny day).
ISO 200. Great for overcast or cloudy days.
ISO 400 and 800. Use these values when the light is
getting dim but it is not yet night.
ISO 1600 and above. Use for indoor or night shots. Also
useful to freeze the action in sports shots. These values
will produce the most noise.

42. ISO 100

43. ISO 800

44. Basic Camera Controls
Most shutter buttons have
two stages.
1. When you press it halfway
down, the camera sets focus
and exposure.
2. When you press it all the
way down, you take the
picture.
