Photography: It’s all about Light

When thinking about photography, it all really comes down to light. That’s what goes onto the cameras sensor, and that is what makes an image. Exposing the perfect picture comes down to your ability to control the light that comes into the camera. There are three settings on your camera that really control the light coming in.

  1. 1. Aperture: The size of the “hole” light comes through to your sensor
  2. 2. Shutter Speed: The amount of time light is being captured by the sensor
  3. 3. ISO: The sensitivity of your sensor.

I’ll cover each of these in separate blog posts. But being able to control these three settings are what will enable you to capture that perfect shot. These all three come together to become the “exposure” of the picture. You’ve probably heard the term “overexposed” or “underexposed” before. By changing aperture, shutter speed, and ISO, you can control the amount of light in the picture and get the perfect exposure.

Below are three examples of exposure:

As a photographer, i can say that the difference between good and great photographic images is all about the light.
How you use, control and shape light makes a big difference in the quality of your image. This information will be very useful to professional photographer. Thank you!
