Understanding aperture is a fundamental step to mastering control of your camera, and that’s where our Aperture Simulator comes in. This simple, hands-on tool lets you explore how different f-stop values affect depth of field and exposure without touching your camera. Whether you’re just starting out or need a refresher, this simulator helps you see how changing your aperture changes your image.

You’ll get a clear visual of how blurry or sharp the background becomes and how light or dark your photo gets, plus see what the aperture is doing inside the camera.
