How to separate subject from surroundings in portraiture?
For classic portraiture we separate our subject from the surroundings by using "selective focus." Choosing a large aperture (lower f/stop, like f2.8) creates very shallow depth of field with only the subject, or just a portion of the subject, in focus. This helps direct the viewer's attention to the subject.
What is the effect of aperture on a photograph?
The other critical effect of aperture is depth of field. Depth of field is the amount of your photograph that appears sharp from front to back. Some images have a “thin” or “shallow” depth of field, where the background is completely out of focus.
What is the role of aperture in flash photography?
While shutter speed’s role becomes controlling ambient light, aperture’s function in flash photography is to purely regulate the amount of light the camera can record from a flash burst. This is a complex topic and we will write a separate article explaining this. We wanted to include it in this section, since flash is tightly correlated to lens aperture.
Why is the maximum aperture important?
For almost everyone, the maximum aperture will be more important, because it tells you how much light the lens can gather at its maximum (basically, how dark of an environment you can take photos).
What is the difference between a small aperture and a large aperture?
A small aperture makes your photos darker, increases depth of field, increases diffraction, decreases most lens aberrations, and increases the intensity of starbursts. A large aperture does the opposite.
What happens when the aperture closes?
As your aperture closes, more and more light from the sides of your lens will be blocked, never making it to your camera sensor. Only the light from the center area will pass through and form your photo! As the diagram above shows, this central area is far easier for camera manufacturers to design.
How does aperture affect exposure?
One of the most important is the brightness, or exposure, of your images. As aperture changes in size, it alters the overall amount of light that reaches your camera sensor – and therefore the brightness of your image.

Aperture is like the “pupil” for your camera system, which can open and close to change the amount of light that passes through. Note the nine blades in this lens, which form a diaphragm to block any light that tries to pass, except through the center.

In reflecting telescope, the aperture is equal to ...

Why use a larger aperture?
Using a larger aperture (f/1.8) allows you to direct the viewer’s eye to the sharp (in focus) elements of a photo, and away from the blurry (out of focus) elements. Leaving the out of focus elements in the image can help ‘tell the story’, without being the main focal point of the image.
What is the maximum aperture of a zoom lens?
The maximum aperture is usually written on the lens as 1:XX (where XX is the widest ‘opening’ or aperture the lens can produce.) It’s a bit of a broad generalization, but the cheaper the zoom lens, the smaller its maximum aperture. Cheap zoom lens = not much cool blurry stuff in your photo!

What does smaller aperture mean?
The smaller the aperture, which would be a larger f/number, also means that less light is entering through the opening of your lens. Conversely, the larger the aperture, which is a smaller f/number, means that more light is able to enter through the lens.
What happens to the aperture when the f/number increases?
As the f/number increases the physical size of the aperture decreases. As the f/number decreases the area in focus also decreases. As the f/number increases the area of focus also increases. As the f/number increases less light is allowed to come through the lens. As the f/number decreases more light is allowed to come through the lens.
Does aperture control depth of focus?
That is not to say that aperture doesn’t play an essential role in controlling depth of focus. Luckily, this concept is quite easy to understand. The smaller f/number that is used, the more shallow the depth of focus becomes. The larger the f/number used, the deeper the depth of focus.
