Photography

  The rule of thirds is a compositional guideline that breaks an image down into thirds (both horizontally and vertically) so you have nine pieces and four gridlines. According to the rule, by positioning key elements along the gridlines, you’ll end up with better compositions.

composition is how the elements of a photo are arranged. A composition can me made up of many different elements, or only a few. It's how the artist puts those things within a frame that help a photograph become more or less interesting to the viewer. A good photograph will take many different parts and combine them into an aesthetically pleasing whole. Composition is how an artist tells a story within the confines of a single frame.  

  Shutter speed is the  length of time  the camera shutter is open, exposing light onto the camera sensor. Essentially, it’s how long your camera spends taking a photo. This has a few important effects on how your images will appear. When you use a long shutter speed (also known as a “slow” shutter speed), you end up exposing your sensor for a significant period of time. The first big effect of it is  motion blur . If your shutter speed is long, moving subjects in your photo will appear blurred along the direction of motion. This effect is used quite often in advertisements of cars and motorbikes, where a sense of speed and motion is communicated to the viewer by intentionally blurring the moving wheels.

  Aperture is the opening in the camera lens. A larger hole allows more light to hit the sensor, lightening your photos. A smaller hole allows less light to hit the sensor, darkening your photos. And by adjusting the aperture setting on your camera, you can adjust the size of the aperture (and, in turn, affect a photo’s brightness).

  Exposure is one of the most fundamental photography terms . 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 the amount of light that reaches your camera’s sensor, creating visual data over a period of time. That time period could be fractions of a second or entire hours.
