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
Portraits or still-life photos mostly acclaimed by people are the ones on 
which the background is out of focus so the subject looks pronounced. 
Depending on the focused areas, a photo can be blurred or sharpened. 
This is called ‘a low DOF’ or ‘a high DOF’.
The depth of field is the focused area around the subject. Therefore, a 
small DOF signifies that the focused area is narrow and a large DOF means 
the focused area is wide.
A photo with a small DOF, which...

DOF depends on focal length
The longer the focal length is, the lower the DOF gets. A telescope lens 
with a longer focal length than a telescope lens with a short focal length is 
better to capture a photo of a low DOF.

lens
DOF depends on the distance between the subject and the 
camera
The shorter the distance between the subject and the camera is, the lower 
the DOF gets. Therefore,...

Optical preview
You can press the Custom button to view the optical preview before 
capturing a photo. The camera adjusts the aperture to the predefined 
settings and shows the results on the screen. Set the Custom button to 
Optical preview. (p. 150)
Composition
It is fun to capture a photo of the beauty of world with a camera. No 
matter how the world is beautiful, however, a poor composition cannot 
capture the beauty of it.

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 guide number
The model number of a flash refers to the flash’s power, and the maximum 
amount of light created is represented by a value known as a “guide 
number.” The bigger the guide number, the more light is emitted from the 
flash. The guide number is achieved by multiplying the distance from the 
flash to the subject and the aperture value when the ISO sensitivity is set 
to 100.
Guide number = Flash to Subject Distance X Aperture value
Aperture value = Guide number...

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 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.
