Aperture
can be defined as the opening in a lens through which light passes to enter the camera. It is expressed in f-numbers like f/1.4, f/2, f/2.8 and so on to express the size of the lens opening, which can be controlled through the lens or the camera.
Moving from one f-stop to the next doubles or halves the size of the amount of opening in your lens (and the amount of light getting through).
Keep in mind that a change in shutter speed from one stop to the next doubles or halves the amount of light that gets in also. This means if you increase one and decrease the other you let the same amount of light in.
One thing that causes a lot of new photographers confusion is that large apertures (where lots of light gets through) are given f/stop smaller numbers and smaller apertures (where less light gets through) have larger f-stop numbers.
So f/2.8 is in fact a much larger aperture than f/22. It seems the wrong way around when you first hear it but you’ll get the hang of it.

worst image
This is my worst pictures as I didn't really hold still and take time on it and it was quite rushed and blurry.
