ISO sensitivity
The exposure of an image is determined by the sensitivity of the camera. 
This sensitivity is based on international film standards, known as ISO 
standards. On digital cameras, this sensitivity rating is used to represent 
the sensitivity of the digital mechanism that captures the image.
ISO sensitivity doubles as the number doubles. For example, an  
ISO 200 setting is capable of capturing images at twice the speed of an 
ISO 100 setting. However, higher ISO...

How the aperture setting, shutter speed, 
and ISO sensitivity control exposure
The aperture setting, shutter speed, and ISO sensitivity are closely 
interconnected in photography. The aperture setting controls the opening 
that regulates the light that enters the camera, while the shutter speed 
determines the length of time that light is allowed to enter. ISO sensitivity 
determines the speed at which the film reacts to light. Together, these 
three aspects are described as...

Correlation between focal length, angle, 
and perspective
Focal length, which is measured in millimeters, is the distance between 
the middle of the lens to its focal point. It affects the angle and perspective 
of captured images. A short focal length translates into a wide angle, 
which allows you to capture a wide shot. A long focal length translates 
into a narrow angle, which allows you to capture telephoto shots.

Depth of field
The depth of field (DOF) is the focused area around the subject.
In general, the DOF can be shallow or deep. In photos with a shallow DOF, 
the subject is sharply focused, the background is blurred and the subject 
stands out. In contrast, photos with a deep DOF have all the elements of 
the photo in sharp focus.
You can create a photo with a shallow DOF by using a telescopic lens or by 
selecting a low aperture value. You can create a photo with a deep DOF by...

DOF depends on focal length
The longer the focal length, the shallower the DOF. A telescopic lens with 
a longer focal length will capture a photo with a shallow DOF better than a 
lens with a shorter focal length.
A photo captured with an 16 mm wide-angle lens
A photo captured with a 100 mm telescope lens
DOF depends on the distance between the subject and the 
camera
The shorter the distance between the subject and the camera, the 
shallower the DOF is. Therefore, taking a...

DOF preview
You can press the Preview button to get an idea of what your shot will look 
like before shooting. The camera adjusts the aperture to the predefined 
settings and shows the results on the screen. Set the function of the 
Preview button to Optical Preview. (p. 189)
Composition
The way that objects are arranged in a photo is referred to as its 
composition. A good composition emphasizes the photo’s subjects 
by drawing attention to them and by balancing them with the...

Using the rule of thirds will create photos with stable and compelling 
compositions. Below are a few examples.Photos with two subjects
If your subject is in one corner of the photo, it creates an unbalanced 
composition. You can stabilize the photo by capturing a second subject in 
the opposite corner to balance the weight of the photo.

Flash
Light is one of the most important components in photography. However, 
you will not always have enough of light in all situations. Making use of a 
flash allows you to compensate for the lack of light and create a variety of 
effects.
The flash, also known as a strobe or speed light, provides adequate 
exposure in low-light conditions. It is also useful in light-abundant 
situations. For example, you can use the flash to provide light when a 
subject is in shadow or use...

Bounce Photography
Bounce photography refers to the method of bouncing light off of the 
ceiling or walls so that the light spreads evenly over the subject. Normally, 
photos captured with the flash may appear unnatural and cast shadows. 
Subjects in photos captured with bounce photography cast no shadows 
and look smooth due to evenly spread light.
