In portrait mode, you camera will automatically use the smallest aperture possible.

a. true ***
b. false

correct.

To determine whether the given statement is true or false, we need to consider the characteristics of portrait mode in photography.

In portrait mode, the camera typically aims to create a shallow depth of field, where the subject is in focus while the background is blurred. This effect is achieved by using a wide aperture (small f-number). A wide aperture allows more light to enter the camera, which helps in creating a shallow depth of field.

However, the statement in question suggests that in portrait mode, the camera will automatically use the smallest aperture possible. This statement is false. In reality, portrait mode aims to use a wide aperture, not a small aperture.

By using a wide aperture, the camera can create a pleasing separation between the subject and the background, making the subject stand out more. This is a desired effect for portrait photography, as it helps to draw attention to the main subject.

So, the correct answer is b. false. In portrait mode, the camera will generally use a wide aperture, not the smallest aperture possible.
