If you're like most photographers, you're probably curious about how aperture, shutter speed, and ISO affect your photos.

In this guide, we'll show you how each affects your photos, and provide a visual guide to help you take the right photos every time. Aperture is the size of the opening in your camera lens.

The smaller the number, the wider the aperture.

Aperture affects depth of field, which is the area in your photo that's in focus. Shutter speed is how long your camera shutter is open for. A fast shutter speed lets in a lot of light, which can make your photos look bright and overexposed.

A slow shutter speed lets in less light, which can make your photos look dark and blurry.

ISO is how sensitive your camera's sensor is to light. A high ISO number means your camera will let in more light, which can make your photos look grainy. A low ISO number means your camera will let in less light, which can make your photos look sharper.
