What is "Apertures" In Photography

The size of the aperture 'round open window' is expressed with f / number. For example: f / 2.8, f / 4, f / 5.6, f / 8, f / 22 etc. In the selection of this number series, the size of the window will be doubled to the smallest number of steps in every step and if the larger the number is smaller, then by half the steps will be smaller . Specifically, shutter speed or 'window timeout' ½ s - ¼ s - 1/8 s - 1/15 s - 1/30 s - 1/60 s - 1/125 s - 1/250 s - 1/500 s decreases by half or decreases by half. So if the aperture value changes one step,

the size of the window is reduced to half and the value of the shutter speed is one step, and the window is doubled while keeping the window open, then the effect of the light in the minasase plus the lens will be the same as before. This is the mutual relationship of Aperture and Shutter Speed.

Another thing needs to be clarified before discussing their application - Depth of Field Daphtha of Field, in photography, determines the distance or the focus of the photo. Large depth of field means that everything near the subject of the subject and subject of the subject will be the focus. In order to increase the depth of the picture, the size of 'Aperture' should be reduced to the size of the 'open windows' ie f / number will be larger.
