Setting The Aperture Value Before Shooting (Aperture-Priority Ae) - Canon EOS 90D Advanced User's Manual

Setting the Aperture Value Before Shooting
( Aperture-Priority AE)
In this mode, you set the desired aperture and the camera sets the shutter
speed automatically to obtain the standard exposure matching the subject
brightness. A higher f/number (smaller aperture hole) will make more of the
foreground and background fall within acceptable focus. On the other hand,
a lower f/number (larger aperture hole) will make less of the foreground and
background fall within acceptable focus.
