This document provides an overview of digital photography, including its history, camera engineering principles, and basic composition techniques. It discusses how photography evolved from silver nitrate to digital sensors, and the key components of modern digital cameras like charged-coupled devices, megapixels, and camera lenses. The document also introduces the rule of thirds composition technique for strategically placing subjects in a photo at the intersections of an imaginary three-by-three grid overlaid on the frame.

3. History
How it started?
Silver Nitrate (AgNO3)
Chemical react “light”, turns dark.
“Negative” to “Positive”

4. Camera Engineering
Milestone of Photography
Pinhole Camera
SLR Camera
Compact Camera
DSLR Camera
Traditional Film to Digital Photographs

5. Camera Engineering
Charged-Coupled Device (CCD)
Light hitting the CCD will be converted to
electrical charge in the sensor
The main components of a photo is made
up of 2 factors:
Luminance (Light)
Chrominance (Colour)

9. Basic Composition
Composition is a “creative” process.
It is drawing your photograph.

13. Rules of Third
The 4 intersections
are positions to place
your subject.
Placing them in these
4 areas generates
special meaning to
your picture.
