A Step Between Auto & Manual

As we discussed in an earlier presentation, Manual Mode

allows you to control all of your camera’s settings –

Aperture, Shutter Speed and ISO.

But you don’t always have to go that far. Thanks to your

camera’s Aperture Priority and Shutter Priority modes,

you can step between Auto and Manual modes,

controlling only two parts of the exposure trifecta.

Understanding Exposure

A perfectly exposed image is ideally lit. An underexposed

image is too dark, while an overexposed image is too

light and can appear washed-out.

You can control exposure by controlling:

ISO – Your camera sensor’s sensitivity to light.

Aperture – The size of the shutter’s opening (f-number).

Shutter Speed – The time your shutter is open and able

to collect information about the scene.

Aperture Priority

Aperture Priority enables you to manually adjust your

camera’s Aperture (or f-number) and ISO. Based on

this, and the available light, your camera makes the

best guess on how to control shutter speed in order to

capture a properly-exposed image.

Using Aperture Priority

You might use Aperture Priority for:

Controlling depth of field.

Shooting in low light conditions.

Shutter Priority

Shutter Priority enables you to set your camera’s shutter speed. This

governs the time your camera has to gather information about the

scene. Shutter Priority is helpful when it comes to both freezing

action, and capturing blurred motion.

Using Shutter Priority

Use Shutter Priority to:

Freeze motion by using a fast shutter speed.

Blur motion, by using a slow shutter speed.

Note: When using slower shutter speeds, it’s imperative to use a tripod.

It’s almost impossible to keep your hands as steady as necessary

for the longer shutter speed times.

This is also true when making use of Aperture Priority to shoot in low light,

because your camera will manually adjust the shutter speed to make up for the

lack of light.

Setting ISO

In both Aperture Priority and Shutter Priority modes, you will set your

camera’s ISO, the number that controls it’s light sensitivity.

The higher the ISO, the higher the light sensitivity.

The lower the ISO, the lower the light sensitivity.

Note: ISO is extremely tricky. Increase it too much and your image can

be “noisy” or grainy. Set it too low and you increase the likelihood that it

will be underexposed.

Most newer DSLRs have guides to help you decide how to set the ISO.

A light meter is also a great tool for determining what ISO to use.

Light meters can also help you determine what shutter speed and aperture

to use.

Getting Started

You can switch your camera to Aperture Priority or Shutter Priority, by turning the dial on your camera to eitherS (for Shutter Priority) orA (for Aperture Priority).

As always, consult yourcamera’s manual formanufacturer-specificterminology and setting instructions.
