The Exposure Triangle comprises aperture, shutter speed, and ISO.
Shutter Speed
Shutter speed refers to the amount of time the camera's shutter is open
to let light onto the camera sensor.
The faster the shutter speed, the faster the shutter opens and closes. The
faster the shutter speed, the less light that is allowed through the sensor.
The longer the shutter speed, the more light is allowed through.
Photography
Shutter Speed
Use Case
Effect
Fast (1/1000, 1/500,
1/250)
Bright conditions, action
shots (sports, wildlife)
Freezes motion, less light
enters the camera
1
Shutter Speed
Use Case
Effect
Medium (1/125,
1/60, 1/30)
General photography,
moderate movement
Balances light and motion,
suitable for everyday
photography
Slow (1/15, 1/8, 1
second)
Low light conditions,
creative effects
Captures motion blur, more
light enters the camera
Very Slow (more
than 1 second)
Night photography, light
trails, astrophotography
Significant motion blur,
requires a tripod to avoid
camera shake
Faster shutter speed = freezes the light to create still crisp still images.
For example: 1/250, 1/400, 1/800, and so on.

Photography
Usage
Effect
Motion Blur
To capture the movement of
subjects, such as flowing
water, moving clouds, or
bustling crowds
Creates a sense of motion and
dynamic energy in the photo.
For example, water in a waterfall
or river can appear smooth and
silky, and traffic lights can
create streaks of light.
Light Trails
To capture the trails of
moving light sources, such
as car headlights, fireworks,
or stars.
Produces dramatic light trails
and patterns, ideal for night time
photography and long exposure
shots.
Night
Photography
To capture scenes with low
light, such as cityscapes,
starry skies, or illuminated
buildings.
Allows more light to reach the
sensor, resulting in wellexposed images even in dark
conditions.
Panning
To capture a moving subject
while keeping it sharp and
blurring the background.
Conveys the speed and motion
of the subject, commonly used
in sports and wildlife
photography.
2
Aperture
Aperture refers to the size of the opening of the lens. The larger the
opening, the more light that comes through and vice versa.
F-stops, also known as f-numbers, are the measurements used to
describe the size of the aperture opening in a camera lens. They control
the amount of light that passes through the lens and hits the camera
sensor. F-stops are expressed as fractions, such as f/2.8, f/4, f/5.6, etc
The closer to zero the f-stop number is, the larger the aperture. The
larger the f-stop value, the smaller the aperture.
F-Stop Range
Use Case
Effect
f/1.4 – f/2.8
Portraits, Low Light
Shallow depth of field, blurred
background, more light
f/4 – f/8
General
Photography
Balanced depth of field and light,
versatile for various scenes
f/11 – f/22
Landscapes, Bright
Light
Large depth of field, more of the scene
in focus, less light
ISO
ISO is a measure of a camera sensor's sensitivity to light. ISO stands for
International Organization for Standardization.
A general rule of thumb is to use the lowest ISO setting possible for the
lighting conditions to minimize noise. A higher ISO will allow for more
light but will increase the noise or graininess of the image.
Photography
ISO Range
Use Case
Effect
Low (100, 200)
Bright, well-lit environments
Less noise, higher image
quality
3
ISO Range
Use Case
Effect
Medium (400,
800)
Moderate lighting conditions,
indoors, cloudy days
Slight increase in noise,
moderate sensitivity to
light
High (1600,
3200, 6400+)
Low-light conditions, night
photography, fast-moving
subjects in dim light
More noise, higher
sensitivity to light
Focal Length
The focal length is the distance between the lens and the image sensor when
the subject is in focus, usually measured in millimeters (mm). It determines the
field of view and the level of magnification of the image.
Photography
4
Larger Focal Length (Higher Number): The view becomes narrower. This is
characteristic of telephoto lenses, which magnify distant subjects and have a
narrow field of view. These lenses are great for focusing on specific, distant
subjects such as in sports or wildlife photography.
Smaller Focal Length (Lower Number): The view becomes wider. This is
characteristic of wide-angle lenses, which capture a broad view of the scene.
These lenses are useful for landscapes, architecture, and situations where you
want to include a lot of the scene in the frame.

For night photography - Try the following:
Low ISO → less noise
Fast Shutter → crisp images
Low F-stop → more light
Colour Settings
Vibrance:
Selectively boosts the intensity of less saturated colours while protecting skin
tones, making the image look more natural.
Saturation:
Increases the intensity of all colours equally, which can lead to an
oversaturated or unnatural look.
