Flexibly Use the Aperture to Make Your Photos More Beautiful

Generally speaking, the subjects of foreground and background in scenery photos should both be taken clearly. Compared with telephoto lens, wide-angle lens can make bigger depth of focus; compared with big aperture, small aperture can bigger depth of focus. And correctly focusing is very important. We all know that the smaller the aperture is, the bigger the depth of focus is, and the clearer the photos are. So, people often use small aperture, like f/16 and f/22. However, if the aperture is too much small, it will damage the definition of photos because of a light reaction named diffraction.

Diffraction defines easily that when the lights come across the lens aperture, the lens edge will disperse the lights. The smaller the aperture is, the bigger the proportion of diffraction recorded in the lights is, and the more indistinct the photo is so that the less the details show in the photo.

In the following situation, you can see the diffraction. The aperture of ASP-C sensor camera changes to f/11 or the aperture of all photo sensor changes to f/16.

To express the diffractions in different apertures, we will show series of photos in f/8, f/11, f/16, f/22. Focusing and whole exposure are changeless, and just the size of aperture are changeable. The after processing of all photos is used the same software and install.

                                   

When the aperture is f/8, all sceneries in the photo are clear and the trees in the background is also good; when the aperture is f/11, the sceneries are good, but as the aperture changes smaller and the depth of focus changes bigger, the sceneries become more indistinct and the details are less bright. This is a big issue in scenery photos, especially in big size photos. The misty plant is just the reason why the scenery photo is unsuccessful.
