![]() Diffraction is an optical effect that causes sharpness to decrease, no matter how good your camera is. If we use a narrow aperture, it will cause lens diffraction. Since the landscape is a wide-open area, it has a foreground, mid-ground, and background by the nature of the frame. So let us take some photos first! ShootingĬhoose the frame you want to shoot, let it be a landscape for instance. The 1st one is shooting, and the 2nd is editing focus stacking images. Stacking means combining received images in post-processing in order to extract different focal points into one image. The basic concept of the method is focusing on different areas with your camera and shooting multiple photographs like that. Let us break down how to do focus stacking. That is why the focus stacking technique becomes a good solution to avoid that issue. We want everything to be in focus, but we also want an optimal image quality. So, even at f/22, everything is in focus but because the sharpness is reduced the quality is affected. ![]() This dependency is shown in the scheme below, how the sharpness corresponds to the aperture. And losing sharpness means fewer details in your shot and poor quality as a result. Thus, having a lower aperture increases the depth of field and makes all objects in the frame stay in focus.ĭoes It look like adjusting the aperture will solve all the issues with focus? Unfortunately, every lens has its sweet spot where narrowing aperture to a certain degree will make your frame lose sharpness gradually. Aperture setting helps with that, we can set it to F / 16 or even F / 20 to make our frame able to focus on all objects. The closer to the edge, the blurry it is. Let us say we have a lot of objects in our frame, but the focus appears in the center of the frame or its set focal point. The problem is that camera focus depends on other settings, such as aperture size and depth of field. Focus as a setting is required to let your camera know what you are focusing on in your frame to get a clear image. No matter of photography skills, probably every person that held a camera once in his life is familiar with such a term as focus.
