Aperture-priority mode allows you
to prioritise the aperture settings,
leaving the camera to automatically
adjust exposure and ISO. Wider
apertures (lower f-numbers)
provide you with a shallow depth-
of-field, meaning you can focus
on just one aspect of your frame.
These settings are generally used

for portrait or wildlife photography

as it is easier to isolate your main

focal point from the background.

A narrow aperture (high f-number)

means a larger portion of your

image will be in focus – great for

landscapes. Aperture-priority

mode is abbreviated as Av on the

Canon dial and A on Nikon.
