The lighting is one of many ways to tell a story through photography. By combining a low f-stop, a moderate ISO (800), and a short shutter speed, an image would appear dark and moody with a dramatic subject. If you took the same picture but added more depth of field and more exposure by adjusting the previous settings, the viewer would be met with a bright and information filled photo. When lighting is combined with strong composition and emotion, a photo is most effective.

The final exposure setting on a camera is the shutter speed. The shutter is a metal curtain that lays in front of the sensor. A shutter the fraction of a second that the shutter is open. The longer the shutter remains open, the longer the camera lets in light. A longer speed also allows of the camera to pick up motion. This means that a subject can appear to be moving. Movement in a photo can tell stories. For example, a car that remains in focus but its background is in motion tells the viewer that the car was moving quickly.

Having discussed aperture, I will move on to ISO. The ISO of a camera implies its sensitivity to light. The higher the ISO number is the more sensitive the camera will be to light. This typically means that a bright day will require a low ISO and a low light setting would require a higher setting. A higher ISO will mute colors and add noise in an image.

Today, I will discuss aperture more in depth (pun intended). When a photo has a background that is out of focus with a subject that is sharp, the camera is set to a low f-stop. The blurry background means that the photo has little to no depth of field. The lower a camera’s aperture, the exposure increases and the depth of field decrease. A larger number will achieve the opposite. Most portrait shots will use a low f-stop to ensure that the model is the focus of the picture. Landscape photos use a higher f-stop so that the entire picture is sharp.

An effective photograph is not taken by simply pointing and shooting a camera. Something I had to learn when I first picked up a camera was that the photographer must tell a story. Lighting is a key component in setting the mood of a picture. Lighting can be manually adjusted to do this. The photographer can change the aperture, ISO, and shutter speed. Aperture, also known as the f-stop, controls exposure and depth of field. ISO, the camera’s sensitivity to light, also controls exposure. Shutter speed allows creative control over motion and exposure.
