what is aperture?

Aperture is the adjustable lens opening that controls the amount of light allowed into the camera. Learning to properly adjust these three settings based on your location and subject is essential for capturing good exposures.

large aperture= shallow depth of field

small aperture= great depth of field

In this photoshoot I experimented with aperture, with some images resulting in being darker then others. In some of these images I used coloured gel sheets to create a colour filter over the images, holding the sheets over the lights.

what is depth of field?

As a result, depth of field (DoF) is the distance between the nearest and furthest elements in a scene that appear to be “acceptably sharp” in an image. The distance between the camera and the first element that is considered to be acceptably sharp is called DoF near limit.

In the image, if a lot of the image is being focused on, this is called large depth of field. In the image, if a small amount of the image is being focused on, this is called narrow depth of field.
