Slide 4

My personal experienceMy personal experience I learned traditional photography in

the 80’s As a hobby I found it expensive due to

cost of film and processing I picked up digital photography

around 1997 Using an Agfa e1280, later switched to

a Nikon Coolpix 950 Main application: photographs for

PhilMusic.com and web applications Result: Shooting much more,

enjoying photography more


Slide 5

What is digital photography?What is digital photography?

Traditional cameras capture images on FILM.

Digital cameras capture images on sensors called Charge-Coupled Devices (or CCDs)

The better the CCDs, the higher the image resolution (measured in megapixels)


Slide 6

Image StorageImage Storage The cameras process the CCD images

and write them as data on memory storage devices (usually flash memory cards)

Image can be previewed on LCD Image is transferred to a computer and

saved as an image file (JPG, TIF, or uncompressed RAW format) Computer obtains the image through a

card reader or a cable file transfer (Serial or USB)

File is edited or printed using software


Slide 7

AdvantagesAdvantages

Image can be previewed instantly… instant gratification.

You can delete on the spot Low cost of operation - no film to

buy or process, you only print what you like

Direct input to computers for editing and filing

Brief Demonstration…. Take a photo Transfer to computer View and Edit
