Photography is a passion, art & creativity that define you just a single click, but to become a best photographer, you must know the basic terms & statistics.

INTRODUCTION TO
PHOTOGRAPHY

3. DEFINITION
3
Process of recording pictures by means of
capturing light on a light-sensitive medium, such
as a film or electronic sensor during a timed
exposure. The process is done through
mechanical, chemical or digital devices known
as cameras. The product of photography has
been called a photograph, commonly shortened
to photo.

4. IMPORTANCE OF LIGHT
• The word "photography" comes from French word
photographie which is based on the Greek φώς
(phos) "light" + γραφή (graphê) "stylus", "paintbrush"
or "representation by means of lines" or "drawing",
together meaning "Drawing With Light.“
• LIGHT – Raw Material of SIGHT

5. HOW IS PHOTO / LIGHT CAPTURED
ON CAMERA?

Both have:
•Lens
•Iris
•Recording Medium
Working Of Camera ≈ Human Vision Concept

6. FOCUS
6
Just like a camera, our eyes also need
to focus. Ever tried this exercise?
inside our eyes This process is
performed by the lens tissues.
In cameras this is done by Optical
Lenses.

7. TIME OF EXPOSURE
7
Most of us have this belief that our
eyes see continuous motion. NO! This is
Untrue. Eyes capture only a frame at a
time just like a photograph. But when we
see successive frames, we perceive
motion.
Cameras capture light by fast action of
opening and closing of a shutter.

8. PHOTOGRAPHIC PROCESS
• Film Photographic Process can be broadly divided
into 3 major steps:
• Ray optics and How light forms images
• Film Processing
• Print Processing

11. DIGITAL CAMERAS
• The digital camera perhaps the
most remarkable instances of
shift from Analog to Digital era.
Conventional cameras
depended entirely on chemical
& mechanical processes. On
other hand, digital cameras
work on the mechanism of
recording images
electronically.

12. DIGITAL CAMERAS
• In Digital photography, lens flashes the image on a sensor
instead of a Film. This sensor (CCD) which is made of semi-
conductor material captures image as a long string of 1s & 0s
that represent all tiny colored dots / pixels.
• We’ll be discussing this in detail in forthcoming sessions
