The aperture setting is also known as light meter setting. It is the setting that controls the light which passes through camera iris. The one who can master using aperture settings can have creative control on the camera. Aperture is the tool that creates magic in photography. Aperture can help you in single as well as multi-dimensional shots. When you release the shutter button, a hole opens that catches a glimpse of the scene. The amount of light that gets in the camera lens depends on the size of the hole that opens.
Factors that can be controlled with aperture
- Depth of the field: Aperture settings helps to add depth to the scene. It is mostly used in photography where the focus remains on the subject. Many times the background and foreground get out of focus. Hence, the picture loses its depth.
- Movement through blur: Aperture setting plays an important role in capturing the movement of the subject. The camera can be set accordingly to capture the movement without any blurriness.
- Freezing the subject: When the photographer wishes to avoid blurriness a faster shutter speed should be used. The photographer needs more light when the shutter speed is higher.
Where to use different aperture settings?
- F/1.4 – F/2.8: This setting should be used when the photographer is taking pictures in low light areas.
- F/4: This is the minimum aperture setting for portrait photography. If the area gets any wider, the subject can get out of focus.
- F/5.6 – F/8: It is used when the photographer takes a picture of multiple people or a group photo. The higher the number of people in the frame the higher the f-number should be used.
- F/11: It is the best for product photography and where the lenses are sharp.
- F/16 – F/22: It is the best setting while taking pictures in bright sunlight or landscapes.
