Golden Guides

Posted: February 22, 2011 in hobi

Here are some tips to help you on your way to growing and developing your photography skills:

Always bring your camera
The number one reason why people miss good pictures is because they don’t have a camera.
Make it a habit to always carry a camera with you, because you never know what you could miss.

Shoot more
If you think you shoot enough – you don’t. Especially if you have a digital camera, because
there is no added cost to taking more photographs. Why take just one picture if you can take
several? Are you in a place you may never visit again? Take a picture, because even the most
boring day to day scenes can become historical in just a few years of time.

Trust your eye
Studying laws of composition is fine, but when it comes down to you must trust your eye.
When you frame the shot, move the camera and explore the scene. When you find an angle or
composition that FEELS good to you, take the picture immediately. You can (and should)
get several more shots.

Train your eye
Look at the pictures you have taken and critique your own work. Did the image turn out like
you planned? Do you like the composition? This self-review stage is essential for you to
improve your photographic “spider-sense”.

Know your camera
You don’t need to memorize every feature right away, but over time you should be comfortable
enough so that operating your camera becomes second nature. It’s like learning to shift gears
or ride a bicycle – only when the machine becomes transparent are you really driving.

Always work on a copy
This essential guide is new for the era of digital photography. Remember that until you make a
backup copy your digital photo is a one of a kind original. Make it a habit to make copies
immediately after loading them from your camera, even before looking at them! Back up your images
onto removable media as often as you can.

Shutter and Aperture

Controlling Exposure
In order for an image to be captured on film, it must be exposed to light.
The camera has two settings that control light, and they work very similar
to the human eye.

The Shutter:
The shutter blocks all light from exposing the film UNTIL you press the button.
Then it quickly opens and closes, giving the film a brief flash of light.

You can control the length of time the shutter remains open by setting the SHUTTER SPEED.

Longer shutter speeds = more light
shorter shutter speeds = less light

Shutter Speed:
Determines HOW LONG the shutter stays open.

The longer exposures ( like 1 second ) give much more light to the film than a 1/1000 of
a second exposure. So even though the number may look bigger, don’t be deceived!

A half second exposure is ONE STOP darker than a one second exposure.
A 1/125 exposure is TWO STOPS brighter than a 1/500 exposure.
A 1/1000 exposure is THREE STOPS darker than a 1/125 exposure.

The Aperture:
Before light reaches film, it must pass through an opening called an “Aperture”.
The aperture is like a pupil. You can control the aperture by setting the “Aperture Opening”,
also known as an F-Stop.

Smaller F-stops numbers = larger openings
larger openings = more light

Aperture Settings (F-Stops):
Like the pupil in a human eye, the aperture on a camera controls light.
It does so by closing up to restrict light, and opening up to let it through.

moving from f16 to f8 is:
TWO STOPS brighter.

moving from f5.6 to f8 is:
ONE STOP darker

moving from f4 to f2.8 is:
ONE STOP brighter

Balancing Shutter and Aperture:
Exposure is about different combinations of shutter and f-stop settings.
These combinations can drastically affect the finished picture. For example,
the following three pictures have been given an equal amount of light, but the f-stop
and shutter combinations make each one unique.

Why is the background all blurred in the right picture, and sharpest in the left ?
Because if the exposure is made with a wide aperture ( like f2.8 ), then objects
farther away from the subject are thrown farther out of focus. This effect is referred
to as “depth of field”

So.. if the aperture is small (like f22) then objects in the background (and foreground )
will appear sharper. However, since more light was required to make the exposure on the left
( 1/4 Second ) the subjects became blurred from MOTION. At 1/250th of a second, the shutter
is fast enough to freeze motion.

Take a stop, Give a stop..
Since f-stop and shutter are both measured in stops, keeping balance is easy. If you take
away 2 stops from the aperture, you can give 2 stops back with the shutter and end up with
the same exposure level.
