Developing smartphones have changed many habits in our lives. For example, we now do most of our work through smartphones. We also photograph every moment we throw, and share some of them on social media platforms. Now we will talk about a common photo taking problem that is seen in almost all smartphones.
Those who take pictures with their smartphones know well; Sometimes objects or people at the edges of the image look different than they should. The image is tilted or elongated. This causes the captured photo not to look as it should. So what is the reason for this? Let’s take a closer look at this often annoying event.
What does a distorted photo look like?
In the photo above, you see one of the clearest examples of everything we have described so far. When you look at the left part of the photo, you can see the bent cabinet doors. On the right, the bezels appear in a way they shouldn’t. On the other hand; The skyscraper, which coincides with the middle part of the photo, looks flat. So why does all this arise? Is there any way to get rid of this problem?
You may encounter this issue if your phone’s camera is wide-angle or you are shooting with an ultra-wide-angle camera.
The cameras of the smartphones on the market are getting better every day. Now we have come to such a point that you can even use a smartphone to shoot a movie. The reason for the bending problem is precisely this developing technology. Our readers who follow the smartphone industry closely know; Even the main camera sensors used in new generation phones now offer wide angles. That’s what’s causing the distortion in the photos. Wide angle. You may also experience this problem if you are using your phone’s ultra-wide-angle secondary camera.
What we call fault is actually related to the structure of the lenses.
The reason for the curvature in the photos we take on smartphones is actually the general structure of the lenses used. So much so that these lenses are specially designed to fit more in a small space. This design also leads to distortion. This is because wide or ultra-wide angle lenses make an object less magnified the further away it is from the optical axis. This is as you can see in the photo above; As it moves away from the center, it causes bending.
Fisheye cameras take advantage of optical distortion
Optical distortion, seen as a problem for many of us, offers unique shots for some photographers. The best example of this is shooting with fisheye cameras. In the photo above, you see a shot taken with a fisheye camera. Fisheye lenses, which have a highly curved structure, maximize optical distortion.
What can be done against optical distortion?
If your smartphone is experiencing distortions while taking pictures, there are a few things you can do. The first would be to center an object you want to photograph. Because we just told you; The reason for this distortion is that objects are magnified less as they move away from the center. If you put the objects in the middle, you can easily get rid of the optical distortion.
One of the ways to avoid optical degradation is to use external applications. So much so that today there are countless photo editing apps designed for Android and iOS. These applications manage to minimize optical distortion. However, if you do not trust the applications on your smartphone, you can also take advantage of professional software such as Adobe Photoshop. Even if your phone can shoot RAW, you can get perfect images with the editing you will do after transferring the raw image to your computer.
