You do not have to be an Adobe Photoshop guru in order to correct this. But just by clicking on the Auto button, the whole distortion is fixed. For example, in the above picture the pillars are looking circular because of distortion. In order to correct wide-angle photography related problems, you simply have to open your pictures in DxO ViewPoint and click on the Auto button next to a specific type of correction. For this, you have to use a software capable of correcting these distortions such as DxO ViewPoint which is able to automatically correct all of these usual distortions. Objects often appear elongated, curved or out of perspective. One of the problem with wide-angle photography is that it distorts the objects in order to fit them in the frame. There are lenses available with focal length of only 2mm but they can cover 170 degree of view. If you want to fit more in the same frame, then you have to use a wide-angle lens which means lens having focal length of less than 35mm. With such smaller view angle, they cannot cover most of the visible objects in front of them.

Regular lenses have a focal length of more than 35mm and their angle of view is usually smaller than 55 degrees. You have to use a wide angle lens to cover more of the view in the same picture. Wide-angle photography is done using a wide angle lens which is used usually with DSLR cameras such as Canon EOS 5DS.
