The Exposure Triangle Explained Click And Learn Photography 3) shutter speed. shutter speed is the length of time light is allowed to hit the sensor. it is measured in seconds. shutter speed is probably the easiest of the exposure triangle sides to understand. to double the amount of light, we need to double the length of the exposure. for example, moving from a shutter speed of 1 ⁄ 60 s to 1 ⁄ 30 s. Aperture. the second piece of our exposure triangle puzzle is the aperture, and just like the shutter speed it can be used in a lot of creative ways once you know what you’re doing. the aperture refers to the mechanical component inside every camera lens, and on most it’s adjustable via the settings.
The Exposure Triangle Explained Click And Learn Photography The exposure triangle is an analogy to explain the main elements that affect the exposure in a photograph:aperture, shutter speed, and iso, and the way that these elements are related. according to the exposure triangle definition, all three elements must be in balance in order to get a perfectly exposed photo. Cheat sheet: understanding the exposure triangle in photography (image credit: future) so a shutter speed of 1 250sec can be doubled by one stop to 1 125 sec, or halved to 1 500sec. an aperture of f 5.6 lets in twice as much light as f 8, or half as much as f 4. and iso400 is twice as sensitive to light as iso200, and half as sensitive as. Luckily, understanding proper exposure is simple enough with the exposure triangle concept. if you’ve ever taken a photo and it’s come out too dark or blown out with a large amount of light, the issue is most likely an incorrect exposure. The exposure triangle is photography talk to describe how shutter speed, aperture and iso work together to expose an image correctly. shutter speed, iso and aperture don’t work independently of each other – you combine all three to get an image correctly exposed to the best amount of light. using the exposure triangle doesn’t come with a.
