Why Go Digital?

• Once captured, digital photographs are already in
  a universal format that makes them incredibly
  easy to distribute, organize, store, and use.

5
Why Go Digital?

• You Can
• Insert digital photographs into word processing
  documents
• Send them by e-mail to friends
• Post them on a Web site where anyone in the world
  can see them.
• Print them on archival photographic paper.

6
Why Go Digital?

• Insert digital photographs into PowerPoint
  programs.

7
Why Go Digital?

• With many digital cameras you can immediately
  view your images on a small LCD screen on the
  back of the camera.

8
Why Go Digital?

• You know instantly how your pictures will look.
• You can view your images on a TV by connecting
  the digital camera to the TV.
• You can view your images before printing them.

9
Why Go Digital?

• You can use a photo-editing program such as
  Photoshop to improve or alter your images.
• For example
• You can crop them - remove red-eye
• change contrast
• add or delete elements
• If you dont like what you see - Edit!

10
Why Go Digital?

• With digital photography, you have the ability of
  instant image capture, and instant results.

11
Digital Cameras

• Digital Cameras do not use traditional film,
  instead they record the image on a solid-state
  electric light sensor we refer to as a CCD.
• (CCD Charged Coupled Device)

12
Digital Cameras

• The CCD is made up of millions of tiny points
  called Pixels.
• The CCD sees what a frame of film in a
  traditional camera would see through the lens,
  when the shutter is open.

13
Digital Cameras

• The light collected by the CCD is then converted
  into digital data.

14
Digital Cameras

• The digital image can be viewed on the cameras
  display screen (monitor), downloaded to a
  computer, edited, stored for archival purposes,
  and also printed in photographic quality.

15
Storage Media

• When you take photographs the image data can be
  stored in the cameras memory, or stored on flash
  memory cards.
• These storage media cards are what we refer to as
  digital film.

16
Digital Film (Storage Media)

• They are erasable and reusable
• They are removable, so you can remove one and
  plug in another.
• They can be removed from the camera and plugged
  into the computer to transfer the images.
• Can be plugged directly into some printers.

Describing Image Size

• The size of a digital photograph is specified in
  one of two ways
• by its dimensions in pixels 1600 X
  1200 pixels
• by the total number of pixels it
  contains 1.92 million pixels

19
Describing Image Size

• 1600 pixels

1200 pixels
1200 X 1600 1,920,000 (1.92 million pixels)
20
Describing Image Size

• The quality of a digital image, whether printed
  or displayed on a screen, depends in part on the
  number of pixels used to create the image
  (sometimes referred to as resolution.)

21
Describing Image Size

• More pixels add detail to an image, sharpen
  edges, and increase resolution.

2816 x 2112 Higher Resolution 6 MegaPixels
22
Simple Digital Guidelines

• The number of pixels in an image, determines its
  size and can have an affect on its resolution.

23
Describing Image Size

• If you enlarge any digital image enough (too
  much), the pixels will begin to show - an effect
  called pixelization.

24
Sensitivity

• The speed or sensitivity, of silver-based film
  is given as an ISO (International Organization
  for Standardization) number that appears on the
  film box.

25
Sensitivity

• The higher the number, the faster or more
  sensitive the film is to light.
• Example 100, 200, 400, 800, 1600, 3200
• Each doubling of the ISO number indicates a
  doubling in film speed.

26
Sensitivity

• Image sensors in digital cameras are also rated
  using equivalent ISO numbers.
• Lower ISO numbers need more light for a good
  exposure than one with a higher ISO

27
Sensitivity

• Higher ISOs enhance freezing or stopping
  motion, and shooting in low-light situations.

28
Simple Digital Guidelines

• A digital image viewed on a monitor screen may
  not have the same picture quality when its
  actually printed.
• Images displayed on the monitor are very
  low-resolution. (For comparison purposes,
  monitors use an average of 72 ppi.)

29
Simple Digital Guidelines

• Point and Shoot Digital Cameras having a file
  size up to 1 Mega Pixel, are great for
  Internet and e-mail type images.
• Not very good for producing photographic quality
  prints
• Price range - 49.00

30
Simple Digital Guidelines

• 6 Mega Pixel Point and Shoot Digital Cameras can
  produce quality images of 8 X 10 and great for
  larger images
• Price range - 149.00 to 399.00

31
Simple Digital Guidelines

• Digital Cameras have different image capture
  settings.
• The correct setting makes it easy to import into
  different applications at the correct size.
• Typically, 2 or 3 mega pixels work great with our
  PowerPoint presentations.
