Aperture Visualizer

Preview different apertures and f-stop numbers

It can take a while for the brain to adjust to higher f-stop numbers meaning a closed down aperture and vice versa. To better be able to assimilate that notion I've put together this tool to easily visualize different apertures with the corresponding f-stop number.

Just drag the slider below to open or close the aperture:

f/1.4
f/2
f/2.8
f/4
f/5.6
f/8
f/11
f/16
f/22
f/32

💡 Remember:

◉ The Aperture is the opening in the lens that let light in to expose the camera sensor.
◉ Wider apertures (smaller f-stop numbers) mean shallower depth of field. Less will be in focus. This can be used for creative effects.
◉ Apertures that are really closed-down (starting at around f/22 and up) can cause diffraction. This varies with each lens, but it's generally a good idea to avoid using very closed-down apertures for this reason.
◉ Along with shutter speed and ISO, aperture is the 3rd variable in the exposure triangle.
