Relationship Between Aperture and Shutter Speed

 
Now it's time in waiting to see, that is to understand the relationship between aperture and shutter speed in acquiring the best light control. If in the examples above, we only use either aperture or shutter-speed only, this time we will try also setting 'manual' by controlling their values ​​simultaneously. This is because we can obtain a better light control and manipulate both correctly.

Aperture settings are called f-stops and indicate the size of the aperture opening. Each f-stop lets in half as much light as the next larger opening and twice as much light as the next smaller opening. From the largest possible opening to increasingly smaller ones, the f-stops have traditionally been those shown to the left. No lens has the full range of settings; for example, the standard lens on a digital camera will range from about f/2 to about f/16. Notice that as the f stop number gets larger (f/8 to f/11, for example), the aperture size gets smaller. This may be easier to remember if you think of the f-number as a fraction: 1/11 is less than 1/8, just as the size of the f/11 lens opening is smaller that the size of the f/8 opening. Many high-end digital cameras have added one or two stops between each of the traditional ones. In the table to the left one-third and one-half stops are shown in red and blue respectively.
How wide you can open the aperture depends on the lens maximum aperture— its widest opening. The term "fast lens" usually applies to lenses that can be opened to a wide maximum aperture for the focal length. For example, a lens with a maximum aperture of f/1.8 opens wider, and is faster, than a lens with a maximum aperture of f/2.6. Faster lenses are better when photographing in dim light or photographing fast moving subjects. With most, but not all, zoom lenses the maximum aperture changes as you zoom the lens. It will be larger when zoomed out to a wide angle, and smaller when zoomed in to enlarge a subject.
