Importance of Exposure in Digital Photography
First let’s find out what “Photography” is and then talk about “Exposure” and the importance of Exposure in Digital Photography.
Here is the description of Photography in Wikipedia:
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. 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……..
As you keep reading you will find it more technical and difficult to understand. But is Exposure that difficult to understand and apply? No not really. We developed a Digital Camera Bootcamp to make Exposure techniques easy to understand.
We have several different Digital photography classes but dedicated one of our workshops just to Exposure due to it’s importance in Digital Photography. In Digital Camera Bootcamp you learn the basics such as shutter speed, aperture, ISO, etc. and then we get to the Advanced techniques such as Metering System, White Balance, Histogram, etc.
