To correctly set the diaphragm, you need to understand how it works. The diaphragm is a device in a camera, consisting of hemispheres, which regulates the flow of light to the matrix. Therefore, in order to correctly set the diaphragm, you need to understand how it works.
Instructions
Step 1
First, let's look at the numbers that indicate the size of the aperture and remember the main characteristic of the f-number: the lower the number, the larger the window on the device that transmits light to the matrix. The larger the number, the narrower the click. Therefore, first of all, we pay attention to the amount of light on the object of our attention.
Step 2
If we need to make a portrait or shoot objects in the foreground clearly, then choose a small f-number, open aperture. Usually these are indicators F1, 4, F2, 8. We mean that the background with such numbers can be indistinct, blurred.
Step 3
If we need to photograph a landscape or an architectural panorama, then we choose a small aperture value, or a small hole for light to pass through. In this case, all objects, not only in the foreground, but also in the background, will be in focus.
