Exposure is the key for a perfect Photograph
Knowing how to use your Equipment is essential to be able to quickly change the settings as the light changes all the time.
Exposure in photography refers to the amount of light that reaches the camera sensor or film. It is one of the most important aspects of photography as it directly affects the brightness or darkness of an image.
There are three key elements that determine the exposure in photography: aperture, shutter speed, and ISO (sensitivity).
1. Aperture
Aperture in photography is basically defined by how much depth of field it will be in your image ( or in a simple way, how much of your background will be in focus or not) and it defines how open or close your sensor will be and it works like this: Smaller the number more open your sensor will be and more light will come in, but the subject will be focused and the background will be blurry and that is recommended mostly for portraits or situations where you don´t necessarily want the background to be sharp. Bigger the number less light will come in but you will have everything focused.
Here is an example of how the aperture works:

2. Shutter Speed
The shutter speed is the setting that defines for how long your shutter will be open or basically how much light and movement you want to capture on your photo.
And it goes from small numbers when there is not much light available or for when you want to create a moving effect. If you have a high shutter speed it means your shutter will open and close very fast freezing the moment, and you can use both, high and slow shutter speed depending on the image that you want to create, or the light that you have available, usually if your hand holding the camera is better to keep the shutter speed above 1/60, that way you wont get blurry images.
3. ISO
Iso is basically how sensitive your sensor will be to the light, so how much light will be captured by your camera. When you have a lot of light available is always good to use smaller numbers for ISO from 100-400 that way you wont get grain on your photos. In the other hand when you don`t have enough light you will probably need to use higher numbers (above 400)
