In photography, stopping down refers to increasing the numerical f-stop number (for example, going from f / 2 to f / 4), which decreases the size (diameter) of the aperture of a lens, resulting in reducing the amount of light entering the iris of a lens. [1] [2]: 112 Reducing the aperture size increases the depth of field of the image.
In photography, stops are also a unit used to quantify ratios of light or exposure, with each added stop meaning a factor of two, and each subtracted stop meaning a factor of one-half. The one-stop unit is also known as the EV (exposure value) unit. On a camera, the aperture setting is traditionally adjusted in discrete steps, known as f-stops.
Diagram of decreasing apertures with conversely increasing f-numbers, in one-stop increments; each aperture has half the light-gathering area of the previous one. It is akin, says the photographer Douglas Peebles , in its simplicity and obviousness to the advice "if you want to be famous for photographing famous people, begin by photographing ...
One technique to make this easier to control is called back button focus: separating focus from the shutter control button by reassigning the AF-on function to a button on the back of the camera body. [8] Some models of a camera may have a dedicated AF-ON button, and menu options to disable the focus via shutter button half-press.

This camera has a fixed shutter speed, so the "EXP VALUE" ring simply sets the aperture. On most cameras, there is no direct way to transfer an EV to camera settings; however, a few cameras, such as some Voigtländer and Braun models or the Kodak Pony II shown in the photo, allowed direct setting of exposure value.
