Basics of Photography: 3 Components of Exposure

If you want to take great pictures with your DSLR, you need to understand three basic things that make up the exposure of photography: shutter speed, aperture, and ISO. Let’s know more about each of the components so you can understand them better.

Exposure

Shutter speed

Adjusting the shutter speed will help your camera know how long it should keep the shutter open. With a long shutter speed, more light will reach the camera, thus allowing you to take better photos even in low light. However, a longer shutter speed may not be good if you want to take the photos of objects that are moving fast.

Aperture

Aperture controls how much light should get to the sensor. If you want to allow a lot of light to reach the sensor, you should use a lower F number like F3.5. on the other hand, a higher F number like f22 won’t allow as much light to get in. it’s important to keep in mind that the Depth of Field also depends upon the aperture of your camera.

ISO

With ISO settings, you can set the sensitivity of the sensor of your camera. Actually, this will make the sensor more or less sensitive to the light. The ISO setting can be between 100 and 6400. If you want to take good photos even in low light, we suggest that you use a higher ISO setting. However, keep in mind that the higher the ISO number, the noisier the image will be.

Lastly, you should keep in mind that all of these components should be adjusted to take good photos. all of three are important for proper exposure. There is an inverse relationship between aperture and speed.

So, this was a basic introduction to the use of three main functions of any DSLR camera. Hope this helps.
