Shutter speed is exactly what it sounds like: It's the speed at which the shutter of the camera closes. A fast shutter speed creates a shorter exposure — the amount of light the camera takes in — and a slow shutter speed gives the photographer a longer exposure.

What Is Bulb Mode on a Camera? Bulb mode simply allows the photographer to take a picture for as long as the shutter is depressed (that means pushed down, not sad…). You can use bulb mode by choosing manual mode or shutter priority, then start scrolling your selector wheel all the way to the end of the shutter speeds.

Motion blur can be one of the most important effects to add to games, especially racing games, because it increases realism and a sense of speed. Motion blur also helps smooth out a game's appearance, especially for games that render at 30 frames per second or less.

Long exposure photography is the name given to the technique in which the camera's shutter is left open during a somewhat lengthy period of time. The resulting image captures the trail of moving objects in front of the camera, while showing still elements razor sharp.

Light art or the art of light is generally referring to a visual art form in which (physical) light is the main, if not sole medium of creation. Uses of the term differ drastically in incongruence; definitions, if existing, vary in several aspects.

Burst photos are perfect because they allow you to capture multiple shots as your subject moves. Just keep your finger pressed down on the shutter button while the subject moves through the scene. Once you've taken a set of burst photos, you can then select the best shots from the action sequence.

Aperture refers to the opening of a lens's diaphragm through which light passes. It is calibrated in f/stops and is generally written as numbers such as 1.4, 2, 2.8, 4, 5.6, 8, 11 and 16.

The distance of the principal focus from the optical centre of a lens is called its focal length. The point on the principal axis, at which the rays parallel to the principal axis, after refraction from the lens, converge at or appear to diverge from is called the principal focus of the lens.

an exposure meter that measures light reflected from only a small area of a subject or scene.

To “crop” an image is to remove or adjust the outside edges of an image (typically a photo) to improve framing or composition, draw a viewer's eye to the subject, or change the size or aspect ratio. In other words, photo cropping is the act of improving an image by removing unnecessary parts.

An aspect ratio is a proportional relationship between an image's width and height. Essentially, it describes an image's shape. Aspect ratios are written as a formula of width to height, like this: 3:2. For example, a square image has an aspect ratio of 1:1, since the height and width are the same

The Lasso tool is helpful for drawing a free-form border around a selected object within an image. It allows you to soften the edges of your selection or add a feathering effect; it's also useful for anti-aliasing.

What does the Magic Wand tool do? The Magic Wand tool automatically selects an object or area of your image, using machine learning to discern what you might be trying to select. If you click on the sky, it selects the sky; click on a person's face, and you have the entire face selected in just seconds.
