Speed shutter and Aperture creates exposer

This blog will explain how your F no. and shutter speed effects your exposure if you don't understand these. I will try to explain

This picture shows the F no.  and shutter speed. This shows the effect of the exposer I 'm going to try to explain this though all right. If your F no. is high like F/16 then your shutter speed will have to be near 1/8 sec for shutter speed if you change the F no. and shutter speed to something like F/2 and 1/500 sec this would have the exact same expose as the first but if you have these numbers at completely different sides like F/2  

and 1/8 sec or even F/16 and 1/500 sec. These are examples but your pictures would be over exposed or underexposed.

 But I'm going to show some photos i have taken today
