Exposure triangle

The exposure triangle controls the quality of your pictures. To operate your Canon DSLR camera, it is necessary to get the three basic elements that make up the exposure triangle which are Aperture, ISO, and Shutter Speed. Understanding how these three elements work will turn you into a pro.


Aperture is an opening in a camera lens where light passes through. Aperture is a very prominent feature among the three exposure triangle elements because it influences many variables of an image. Learning how to control the aperture is key to taking good quality pictures.

Aperture is measured in ‘f-stops,’ which extend the size of the lens as the f-numbers decrease. For example, an aperture f/4.0 is admitted a larger or wider aperture lens, which happens in a shallower depth of field. Aperture f/4.0 lets in twice the amount of light as an aperture of f/8.0, which is a smaller lens size that lets in less light, resulting in a deeper depth of field.

ISO measures your camera sensor's sensitivity to light. Forever try to shoot your pictures on a low ISO for giving you better quality images. If you are shooting in a dark situation, then you require to adjust the ISO to a high setting. If on the other hand, you are working in a very bright environment, then you need to use low ISO settings.

Shutter Speed

A camera shutter is a curtain in front of your camera sensor. When you fire your camera, the shutter opens and reveals the sensor to the light that passes through the lens. It is responsible for blurring or freezing images also.

Long shutter speeds expose the camera sensor to a bunch of light giving you a sharp image whereas a fast shutter speed will expose your image to very little light resulting in a dark photo. Consequently, long shutter speeds are excellent for night photography or low light photography.

Exposure Compensation

Usually found on a small +/- button near the shutter, this is one of the most valuable functions to learn how to use.  It permits you to either increase or decreases the camera's default meter reading to account for the actual brightness of a scene.

White Balance

White balance helps existing colors truthfully on your video camera by managing the temperature of your white light. Light temperatures can vary between natural sources and bulbs, creating unwanted or unnatural color tones in your photographs.


Ok, so now you know a little bit about ISO, shutter speed, aperture, and some other functions. Now it is time to practice. Practice makes everyone perfect. Go through and change the setting of your Canon DSLR camera and do it by yourself to become a pro in the camera world.
