Photography 101 Series| Part I: Understanding Exposure


Welcome to the first week of my new

Photography 101 Series: Mastering Your Camera Settings!

This is basic beginner photography knowledge and tips that can help you on your photography journey---whether you are a blogger, photographer or hobbyist.

This series will be broken down in  3 parts and the first post can be found here of the breakdown of each subject in the series.

So lets begin...

Part I: Understanding Exposure

  • ISO
  • Aperture
  • Shutter Speed

 The three elements (exposure triangle), ISO, Aperture and Shutter Speed help to make up the main components of exposure in your camera. Exposure meaning the amount of light measured in units that allows it to reach the electronic sensor in a digital camera.

What is ISO?

ISO measures how sensitive the camera is to light. In most cameras, ISO speeds are 100, 200, 400 and 800. These speeds can increase with the level of camera that you purchase (point and shoot vs dslr).

*Quick Tip- Lower ISO= Less Grain/Noise Higher ISO=More Grain/Noise

What is Aperture?

Aperture controls how much light enters the camera through the lens. Aperture allows you to be able to adjust the depth of field in a photo. Aperture is my favorite mode on my camera, because I love taking macro (up close) shots.  Depth of field determines how much of the subject is in focus and how much the background will be blurred.

*Quick Tip- Shallow Depth of Field= f1.4-f5.6 ( More Light+ Blurred Background) Deep Depth of Field=f8-32 ( Less Light+ Background in Focus)

What is Shutter Speed?

Shutter Speed (exposure time) is how long the light entering through the lens (aperture) exposes the sensor. The shutter speed is very important, especially when shooting moving subjects. The shutter speed completely determines the motion blur or sharpness of the subject in your picture. Shutter speeds range from 1/30-1/4000 fractures of a second.

*Quick Tip-Slower Shutter Speed=Slows Motion (1/30 or slower) Faster Shutter Speed=Freezes Action (1/250 or more)

So that was a quick review of understanding exposure. I hope this gives you a better understanding of learning to use the light to your advantage in photography.

I've also found a great infographic with all of the important information for understanding exposure.
