If you’re a beginner photographer, it can be helpful to have a simple guide that helps you understand the different settings that you can toggle on your digital camera.
The three settings in this chart are part of what photographers like to call the exposure triangle.
The aperture is a structure in your lens that works much like the iris in our eyes. It opens and close to let more or less light in, and also changes the depth of field, or how many different objects can remain in focus in the shot at the same time.
Second is the shutter speed, which controls how much time the camera’s shutter remains open when taking a photo. A longer shutter opening will let in more light but may also cause blurring if any motion occurs while the photo is being taken.
Last one is the ISO which is the digital camera sensor’s sensitivity to light.
