Think of the aperture number as a fraction.
eg: 1/1.4, 1/2, 1/3.5, 1/4, 1/5.6, 1/8, 1/11, 1/22.
1/2 is larger than 1/4 which is larger than 1/5.6 etc.
1/2 a pie is a larger slice than 1/4 of a pie.
Instead of the size of a slice of pie, the aperture, that is the hole through which light may enter your camera through the lens, is made small ( 1/22 ° ) or larger
( 1/4 O ).
In photography the "f" is put in front of the fractions to confuse us. eg: f1/4, f5.6 etc.
So think of "f" as the number "1" in the fraction. Thus f5.6 = 1/5.6, f8 = 1/8, f22 = 1/22.
So 1/8 of your pie ( aperture = hole ) is bigger than 1/22 of your pie (aperture = hole ).
I had better stop before I confuse myself.
