• Introduction

Basic DigitalPhotographyWorkshop Introduction
Photography" is derived from the Greek
words photos ("light") and graphein ("to
draw") The word was first used by the
scientist Sir John F.W. Herschel in 1839. It is a
method of recording images by the action of
light, or related radiation, on a sensitive
material.
Simply, photography literally means drawing
with light.

• Types of Cameras

Basic DigitalPhotographyWorkshop Types of Cameras
1. Point-and-shoot
2. Mirrorless
3. Single-lens reflex
4. Medium format
5. Large Format
6. Camera Phones

Enter: The Smartphone

The principles of operation is basically the
same. The most important thing that
distinguish one camera from another is the
sensor size

Pros & Cons

Basic DigitalPhotographyWorkshop Basics of Photography
Basically, the pictures you take is
about light

Three basic things are needed to
understand photography. These are
the factors that determine the
correct exposure of your pictures.
 Aperture
 Shutter Speed
 ISO / Film Speed

Once you understand how these things
affect your images and how they relate to
each other, everything else just falls into
place.
Each of these three elements affects your
image in two ways: one is physical, and one
is creative.

First we take a look at the camera
Second we look at how all these
elements work together to produce
images.

Aperture
SOURCE: http://www.gpsphotography.com/wp-content/uploads/2012/10/aperture-range-lenses.jpg

 Aperture
1. The aperture controls the volume of light
that enters the camera by adjusting the
size of a hole in the camera’s lens
2. A large hole lets in lots of light and is
defined by a small number (ex: ƒ/4)
3. A small hole lets in a small amount of
light and is defined by a large number
(ex: ƒ/16)

 Aperture
4. The smaller the aperture’s hole, the
more things are in focus near-to-far in
a scene; when the aperture hole is
large, fewer things are in focus near-
to-far.
5. The aperture value is either set by the
camera in one of the automatic
shooting modes, or set by the
photographer in manual mode

Aperture (F): 16

Aperture (F): 2.8

 Shutter Speed
1. The shutter controls the length of time that
light has to enter the camera.
2. Shutter speeds are expressed in fractions of
seconds (ex: 1/250 of a second, usually just
1/250 or even just “250”).
3. A long shutter speed lets in lots of light and is
defined by a large number (ex: 1/2 or 1/8).

 Shutter Speed
4. A short shutter speed lets in a small amount
of light and is defined by a small number
(ex: 1/500 or 1/1000).
5. The shorter the shutter speed, the more the
camera can stop motion in the frame; the
longer the shutter speed, the more motion
in the frame will be blurred.
6. The shutter speed is either set by the
camera in one of the automatic shooting
modes, or set by the photographer in
manual mode

Shutter Speed: 25s

Shutter Speed: 1/30s

1. Film cameras can only change ISO
values by changing the film in the
camera; digital cameras can change the
ISO at any time with a camera setting.
2. A digital camera’s ISO changes via
electronics; an amplifier turns up the
“volume” of light sensitivity for high ISO
and turns it down for low ISO.

3. The higher the ISO number, the more
sensitive to light the camera will be; the
lower the ISO number, the lower the camera’s
light sensitivity will be.
4. Lower ISO numbers generally will result in
sharper, better-quality photographs; higher
ISO numbers generally result in photographs
that have increased grain or noise
5. As ISO values change, they change by whole
or third “stops”

The Combination of the three aforementioned elements
form the basis of all photography.
1. Exposure is controlled by Aperture, Shutter Speed and
ISO setting
2. Each exposure control has a relationship of 1:2 or one
“stop” of difference
3. An in-camera light meter reads light in scene and helps
set the aperture, shutterspeed and (sometimes) the ISO
4. The meter bases its exposure suggestions on an
“average” amount of light reflecting from objects in the
scene
5. This “average” light is based on a middle gray reflectance
6. There is a “correct” exposure (total amount of light) for
every scene, but the combination of aperture, shutter and
ISO can be different
