Why do you need aperture camera

Purchasing a quality camera, not worth to stay with the default settings. In this article we will explain what is required such a function as the diaphragm, and how to use it.

Physically, the aperture of the camera represents the petals of the lens and letting in so much light. The better the lens, the more petals it has, and the more beautiful the effect of the blur. Won't tell you in words what pictures you can get, and show everything clearly.

These pictures depict children, and at first glance the photo is almost the same. But the first image we can clearly see the boy in the background, and the second – background for girl all blurred. Note that this is not the maximum degree of blur, and manually (in photoshop) the same effect cannot be achieved.

Now explain how the aperture of the camera was set up in both cases. In the first photo, the aperture is closed, as a result, we see the whole picture clearly. In the second photo, the aperture is more open, causing the boy to be seen. We have reviewed and it is clear that at maximum aperture we get a blurred background, and when closed, the hole is clear.

In Almost all cases, the diaphragm of the camera is denoted as “f/” and a number that shows the degree of openness of the gap. First you will be difficult to remember all the values, so it is enough to know that the smaller the number, the more blurred the background, and the more-the better visible objects in the background. The following image displays default values that are present even in ordinary cameras. You can see how changing the aperture depending on performance.

Despite the fact that the function of aperture priority is on the compact cameras, to achieve the effect of blurred background are impossible. In order to understand the difference, it is enough to try out the camera SLR and professional. Believe me, the difference in quality will be noticeable to the naked eye. And the number of functions settings you will be pleasantly amazed. Do not rush to learn everything at once in the beginning and deal with each parameter separately and then choose manual mode and compose them.

The photo with the ladybug is clearly seen that the iris is open fully. This picture can be made with any professional equipment-regardless of brand-Nikon, Canon. Camera, most importantly, needs to be mirrored or professional.

In conclusion, it is worth saying that the aperture of the camera can focus on a specific object by selecting it and blurring out the background. In the photograph above with ladybug clearly shows this effect, because you only see the insect, and the rest – not so important. Closed aperture of the camera is needed when images of the streets, the landscapes, the crowds, where you want all the photo was in focus.

As you can see, it is not so difficult as it seemed at first, but before proceeding to further study of the art of photography, it is good practice at this stage.
