Graphic reminders
All Nikon cameras show what aperture you’re using (f/11 in the example here). However, D3xxx and D5xxx-series Nikons can also give you a graphical depiction of the aperture on their information displays. If you’d like to see this, go to the Setup menu, select ‘Info display format’ and check Graphic. The diagram shows roughly how wide the aperture is set and is a reminder that bigger numbers relate to small apertures.
