DESCRIPTION
In photography, the exposure settings of aperture, shutter speed and ISO speed are similar to the width, time and quantity discussed above. Furthermore, just as the rate of rainfall was beyond your control above, so too is natural light for a photographer.TRANSCRIPT

Understanding ExposureAchieving the correct exposure is a lot like collecting rain in a bucket. While the rate of rainfall is uncontrollable, three factors remain under your control: the bucket's width, the duration you leave it in the rain, and the quantity of rain you want to collect. You just need to ensure you don't collect too little ("underexposed"), but that you also don't collect too much ("overexposed"). The key is that there are many different combinations of width, time and quantity that will achieve this. For example, for the same quantity of water, you can get away with less time in the rain if you pick a bucket that's really wide. Alternatively, for the same duration left in the rain, a really narrow bucket can be used as long as you plan on getting by with less water.

Aperture
Aperture: Controls the area in which light can enter your camera and is measured by f-stops.

• The wider the aperture the more light the camera is able to collect. Aperture also impacts the depth of field. The larger the aperture the shallower the depth of field.

Shutter Speed
Shutter Speed controls the duration of the exposure. The longer you leave it open the longer the sensor is exposed to light.

Shutter speed can also be used creatively to add motion or freeze action.

ISO Speed
ISO controls the sensitivity of your camera’s sensor. The lower the iso number the less sensitive the sensor. Careful though, increasing your iso will also lead to an increase in noise.

Exposure Triangle
The key is to find the right balance of all three. If you let in too much light, your Photograph will be “overexposed”. If you do not let in enough light your Photograph will be “underexposed”.
