As we build our Pinhole Camera we are comparing the parts and functions of the parts to a Real film Camera, and also to our eyes...

The aperture is the opening in the Lens. The lens will have a mechanism that opens up and closes down the opening. The sizes of those openings are called f-stops. Look below for a comparison of f-stop sizes. The mechanism on this lens is a series of blades that are controlled by the aperture ring. When you turn the outer aperture ring on the lens, the blades close and open. You will feel a click or a place that the ring stops at, the ring is made that way so you can adjust to a size easily. That is why they call the sizes "stops". The "f" stands for focal ratio.
We drew and labeled an aperture in class. We discussed the interesting fact that the f-numbers are really fractions, so the largest number here, f-16 , is the smallest opening. And the smallest number here, f-1.4, is the largest opening!
