Rule of thirds
a composition guideline that divides an image into nine equal parts to create a grid. Helps create balanced and visually appealing photos.
level horizon
is crucial for a balanced and stable-looking image. Can be achieved with a camera's grid display, and post-processing software.
shutter speed
the length of time a camera's shutter stays open = how long the sensor is exposed to light when taking a picture; a fast shutter speed = shutter opens and closes quickly, capturing less light. Slow shutter speed= shutter to remain open longer, letting in more light and potentially blurring motion in a scene.
ISO
a camera setting that controls how sensitive the camera's sensor is to light. One of the 3 main elements of exposure, along with aperture and shutter speed.
F-Stop
a measurement of the size of a camera lens's opening, or aperture. It's written as "f" followed by a number, such as f/2.8 or f/8.
depth of field
the range of sharpness in a photograph, from the closest to the farthest objects.
resolution
the number of pixels in an image, determines the level of detail. A higher resolution= more pixels, which results in a sharper, clearer image.
compression
a process applied to a graphics file to minimize its size in bytes without degrading the image quality.
fill the frame
a technique that fills the frame with the subject, often eliminating the background
subject
the main focus of the image, and is the person, object, or animal that is depicted. The subject is what the image is about, and it helps determine the composition, mood, and message of the photograph
background
the part of a scene that's furthest from the viewer. It can also be the area behind the main subject.
foreground
the part of an image that's closest to the camera. It's the first part of a photo that a viewer sees, and it's often used to grab their attention.
