Understanding The Exposure

Understanding The Exposure in Photography for Beginners

Obviously, we all want to take better photographs, but let’s face it that sometimes it is not that easy as “point and shoot”! Understanding the Exposure in photography helps you to capture the best possible image each and every time.

For understanding the exposure, first let’s find out what “Photography” is and then talk about “Exposure” and the importance of Exposure in Digital Photography.

Understanding The Exposure

Wikipedia explains Photography as:

“Photography is the art, science and practice of creating durable images by recording light or other electromagnetic radiation, either chemically by means of a light-sensitive material such as photographic film, or electronically by means of an image sensor.[1] Typically, a lens is used to focus the light reflected or emitted from objects into a real image on the light-sensitive surface inside a camera during a timed exposure. The result in an electronic image sensor is an electrical charge at each pixel, which is electronically processed and stored in a digital image file for subsequent display or processing.”

So photography is not just clicking the shutter and capturing the image. It has more technical aspects. One the most important techniques is Exposure. Let’s read what Wikipedia says about Exposure:

“Camera controls are interrelated. The total amount of light reaching the film plane (the ‘exposure’) changes with the duration of exposure, aperture of the lens, and on the effective focal length of the lens (which in variable focal length lenses, can force a change in aperture as the lens is zoomed). Changing any of these controls can alter the exposure. Many cameras may be set to adjust most or all of these controls automatically. This automatic functionality is useful for occasional photographers in many situations……..”

More Confused?

No kidding! These quotes from Wikipedia don’t help understanding the exposure any easier. As a matter of fact, as you keep reading you will find it more technical and difficult to understand. Don’t give up yet, stay with me and I will help you understanding the exposure completely.

What is a Correct Exposure?

Exposure is the most important part in Digital or film photography. Exposure can make a photo “Amazing” or “Junk”! A correctly exposed photo is a picture that shows the same brightness and contrast as human eyes can see in the scene. Here is a sample of correct exposed photo;

If exposure is too low, you’ll get an Under Exposed image:

Under Exposed

An underexposed photo is darker and does not have the same brightness and contrast as our eyes can see.

And if the exposure is too high, the result is an Over Exposed photo:

Over Exposed

Same scene, but overexposed image. Notice  the lack of contrast and colours.

Controlling the Exposure

The total amount of light that reaches the sensor makes the exposure. We can control the total amount of light by using the Time or Duration of light (Shutter Speed), Volume of Light (Aperture), and Sensitivity to Light (ISO).

In this new series of articles I am going to discuss all the controls and how to use them. Stay tuned for these articles and as always feel free to contact us if you have more questions. Follow us on Facebook, Instagram and Twitter for new tutorials and tips.
