Photography 101 | Aperture
Aperture is often referred to as an F-stop and written as f2.8. The smaller the number the more light is being allowed onto you the sensor; the larger the number the less light enters. This also affects the depth of field in your images. Higher aperture numbers will have a greater depth of field and more of your subject will be in focus. Landscape Photographers will usually use a higher aperture because they want the flowers in the foreground and the mountains in the background in focus.
Notice how the image below has more in focus. The F-stop is higher so more of the image from foreground to background is in focus.
- lower number means more light
- higher number means less light
- lower number means narrow depth of field
- higher number means increased depth of field
