If you look closely at the camera lens, you will find round or ring-like metal blades.These blades open and close: it opens to widen the opening, and it closes if you want the opening to narrow down.ISO, Aperture and Shutter are known as the “exposure triangle”.

Let us look at each element closely and understand how they can help you achieve the right exposure.
The ISO refers to ratings that define the sensitivity level of your camera to light (a more technical exploration can be found here).
This is the shutter mechanism that determines the light reaches your sensor.
The shutter speed is measured in fractions of a second, e.g. So, if you use the example given, 1/100s, what this means is that your camera sensor is exposed to light for only one hundredth of a second.
For shallow depth of field photos, use a larger aperture size (i.e. So, if you need to remember one thing, it is this: when you adjust the aperture by just one stop, you either halve or double the amount of light that goes through your camera lens.
What is important, though, is that you keep practicing until you familiarize yourself with the different f-stop values, and until you produce the image/s you want.
If you increase the f-stop to decrease the amount of light getting to the sensor, you will also need to adjust the shutter speed and the ISO for an equivalent exposure; otherwise, your image might come out blurry or too bright; overexposed or underexposed.
This is just a simple introduction to the three elements that make up the exposure triangle.
If you need to remember one thing about shutter speed, it is that when the shutter speed number is a smaller fraction, the faster the shutter opens and closes.
If you want to control the shutter speed manually, go for Shutter Priority (S or Tv on your camera) or manual mode.
