Shutter Speed

The time which the shutter opens to enablelight to strike recording sensor.

Measure in seconds or fractions of a second,

eg 1 sec, 1/500 of a second, etc

Tripod required for shutter speed >1/60 sec

1/2000 sec1/15 secTo control shutter speed, use TV or M mode.



Fast Shutter Speed

Characteristics of fast shutter speed shooting:

-Objects frozen in movement

-Often used in sports photography

Slow Shutter Speed

Some characteristics of slow shutter

speed shooting (at night):

-silk-like water texture

-light trails for moving subjects

-Clouds at night can be seen in shots

Aperture

•Size of the lens hole to allow light to enter thecamera. Indicated by f numbers, eg f/16, f/11, f/18

•The Bigger the Number, the Smaller the Aperture

•Determines the Depth of field

The Aperture stated on the lens also

determines how fast the lens can

focus; the smaller the number, thefaster it is.

Hence the term “Fast Lens”



Depth of Field

- Depth of Field = Degree of Background blur - Determined by Aperture value.

- Bigger aperture = stronger background blur.

- At f/16, almost everything from Front to Back will be infocus

f/2 f/16

To control shutter speed, use AV or M mode.



Different Aperture Settings

f 2.0 f 2.8 f 4.0 f 5.6

f 8f 11 f 16 f 22



How to achieve background blur?

Depth of field is influenced

mainly by

Aperture size used Distance from the subject Magnification of the image

Depth of Field and Proximity

The nearer you are to the subject the lesser the depth of field.




Depth of field with Telephoto lensHigh magnification (telephoto) reduces depth of field.




ISO directly affects the range of Shutter speedand Aperture value available for a proper exposure, hence it is also widely known as“speed” ( especially during film days)

It can extend shutter speed and aperture range or

limits the range depending the situation you arefacing.

At low ISO you may need a tripod to take pictures when there is insufficient light.

High ISO contributes to noise on the image, however you may not need a tripod depending on light level.

ISO Range

100 200 400 800 1600 (3200**)

Exposure Control – ISO (ASA)

** EOS 20D or better models activated thru custom functions



High ISO shooting

Higher ISO can reduce image blur with the increased in

sensitivity thus allowing faster shutter to be used.

Can be used in low-light areas where flash is prohibitedFor eliminating “black background effect” from Direct Flash.

ISO 100 (manual setting)

AUTO (Flash OFF)

ISO 800 (manual Setting)



Shooting at different ISO

Disadvantage of

high ISO

shooting:

More noise



Exposure

- Determine the “brightness” of a photo:

-Too Bright: Over-exposed

-Too Dark: Under-exposed

- Elements that determines Exposure:

-Shutter Speed

-Aperture

-ISO

- Changing any of these settings will affect

your overall exposure.

Understanding “Stops”. What is a Stop?

f1.0 f1.4 f2.0 f2.8 f4 f5.6 f8 f11 f16 f22 f32 f45

In Aperture, value measured in f-number

30” 15” 8” 4” 2” 1” 1/2 1/4 1/8

1/15 1/30 1/60 1/125 1/250 1/500 1/1000 1/2000 1/4000 1/8000

In Shutter Speed, value measured in seconds

A stop is actually an Exposure Value (EV)

100 200 400 800 1600 3200

In ISO value

Each time when you increase the EV, you will be doubling the amount of light. Wheneveryou decrease or stop-down, you will be halving the amount of light.



In summary, for exposure:

Let the correct exposure value be x:

Aperture (a) + Shutter (s) + ISO (i) = X

If you increase the aperture by 1 stop, you

have to adjust the shutter or ISO value by1stop to maintain the correct exposure.

Metering System



Understanding meteringWhen your subject is occupied bypredominantly “white” or “dark” background,you need to compensate.

Evaluative metering No compensation,

resulting in Under exposure

Evaluative metering Compensated with +1 stop,

resulting in Correct exposure



Understanding meteringWhen your subject is occupied bypredominantly “white” or “dark” background,you need to compensate.

Evaluative metering No compensation,

resulting in Over exposure

Evaluative metering Compensated with -1

stop, resulting in Correct exposure



Understanding metering

For now, just use evaluative metering for your shots.

Use Partial/Spot metering

when shooting high

contrast environment.

First, Lights! - Photography is all about ‘painting’ with Quality Lightings!

Since we cannot make anypicture in the absence of light,therefore lighting is the mostimportant factor in all types of

photography.

All your technical decision onISO, Shutter Speed and Aperturedepends on the quality andquantity of light.

So before you begin exposingany shots, you must be aware of

the lightings conditions.Picture source: www.jinolee.com.sg

Use AE lock to helpmaintain correctexposure when re-compositing your shot.

Getting Composed – Rule of Thirds

Photo: unknown

By placing your main subjects/objects at the intersection of thirds,the results will be aesthetically stronger. This applies to horizon aswell. Placing the horizon line at the intersection of thirds will adddynamic to your final image.



Getting Composed – Big & Bold

Big and Bold also known as Fill the Frame




Getting Composed – Using Colours




Keep the Horizon Straight

When shooting Landscape and Architecture, make sure youkeep the horizon straight.

Slanting horizon is a big NO-NO! (unless you’re going for acertain effect)

Position the Horizon at the intersection of thirds

Foreground Interest

Use foreground subject to add scale to your pictures and also to enhance your composition,

making it more interesting.

Getting Composed – Background

Example of “destructive background”



Lead-in Lines(AKA Guiding the eyes)

Lead-in lines will help leadviewers to your point of focus or

subject instead of leaving theviewers to wander around thepicture.

Lead-in lines will also make anordinary composition lookinteresting.


Getting Composed – Leading Lines



Use an element such as arch,leaves, mirror & etc to frame around

your main subject. Your ‘frame’

must NOT compete for attention

with your subject but to complacent

the subject.


Framing



more practical tips

Point of Focus (focus of attention)

In every picture you must have a Point of Focus

aka Focus of Attention.

All other composition elements will be buildaround this very important Point of Focus.

Without, you will find that your eyes will bewandering restlessly within the frame andsomehow find the image not interesting.

Taking Charge

Take control of your picture-taking and watch your picturesdramatically improve.

Direct your shots, not just a passive picture-taker.

A good photographer directs and takes charge of the shot. Pickthe location and make necessary changes to you subject to make

them look better.

Theme

What is Theme? A theme is where

your viewers will be able to

immediately identify and understand

what your picture is all about.




more practical tips

Making Use of Reflections

Reflections will definitely open up anew perspective and add dimensionsto your pictures.

Shoot reflections not only from water but any reflective surface such asglass, plastic and etc.




more practical tips

Shoot Silhouettes

Silhouettes, if carefully taken, are a powerful element to

further enhanced your picture when you are faced with no other choice but to shoot into the light.

Note: Do not stare directly into the sun when shooting silhouette.




more practical tips

Less is More

Try not to include too many things inside a single frame as it willonly cluttered and confused your viewers.
