Focal length is the distance between the centre of the lens and the camera’s sensor.
A shallow depth of field means that objects become blurrier at closer distances. While not part of the exposure triangle, focal length and depth of field - the distance at which objects are still sharp and in focus in a picture - may affect how you adjust other settings. “Let’s say you have a small aperture, maybe like an f/16, but you’re still not getting enough light in your scene. “ISO comes into play when you want to capture action,” says photographer Heather Barnes.

Film still comes with your choice of ISO, but now ISO is associated more with adjustments you can make in digital cameras. Different films were more or less sensitive to light and ISO was a way to quantify that sensitivity. If ISO is too low, a photo will be underexposed. Higher ISO in relation to shutter speed or aperture can result in pictures filled with digital noise, which looks grainy. Low ISO means the camera’s sensor is less sensitive to light and high ISO more so. ISO represents the sensitivity of the light sensor within the camera. A greater depth of field would be used for something like landscape photography, where everything from nearby trees to distant mountains appear crisp, in focus and well defined. Imagine a piece of cake that looks crisp and clear, but the edge of the plate right behind it is blurred. An aperture of f/8 would indicate a smaller aperture, whereas one of f/2 would open much wider and let in more light.Ī food photographer might use a wide aperture to create a shallow depth of field where the subject is in focus but the background is blurred out. The lower the f number, the wider the aperture, and vice versa. Your aperture setting is measured in what’s known as an f number, also called an f-stop. It functions much like the pupil in a human eye, which dilates to let in light and narrows in bright settings. For instance, photographers who capture fleeting instances of athletes in motion might only have their cameras open for 1/1000 of a second to freeze the exact moment when a basketball player makes a slam dunk.Īperture is the adjustable lens opening that controls the amount of light allowed into the camera. If you’re photographing something even faster-paced, like sports, you’ll want to use a very fast shutter speed. If you’re photographing an event and want to get candid expressions of people talking, you’ll want a shutter speed of 1/400 or faster. Tripods are great tools to help motion blur.įaster shutter speeds are good to capture fast action. Keep in mind that the longer you leave a shutter open, the more motion blur you’re likely to have. In long exposure photography, the photographer can sometimes keep a shutter open for minutes or even hours. Some nighttime photographers leave their shutter open for seconds.
You can still get well-exposed and well-lit pictures in low-light conditions if you set up your camera just right. If there’s less light, you’ll likely want a slow shutter speed. Appropriate shutter speeds vary depending on lighting conditions. Common shutter speeds for daylight pictures range from 1/1000 to 1/200 of a second. Modern camera shutter speeds are measured in fractions of a second. Shutter speed is the amount of time that the camera’s shutter is open and measures the length of exposure. Those settings are shutter speed, aperture and ISO. Instead, exposure is made up of three different data settings known as the exposure triangle. There is no single camera setting for exposure.

Learn these basics to better understand camera exposure and discover how to get the right exposure for your work. Underexposed images are dark and hard to see. Overexposure leads to overexposed highlights and faded-looking images. That time period could be fractions of a second or entire hours. Exposure is the amount of light that reaches your camera’s sensor, creating visual data over a period of time.
When you take a picture, you press the shutter button to open a camera’s aperture and light streams in, triggering a response from a sensor. Exposure is one of the most fundamental photography terms.
