Some time ago I was involved in a little discussion on G+ about advantages of using the wide angle lens. I promised the guys to share some of my experiences with using it. So here we go.
My motivation for wide-angle lens
I started using the wide angle lens for shooting landscapes, after studying some stunning photos on the Net and asking myself how people made them. And after buying my lens (Tokina 11-16/2.8 DX) I wasn't disappointed:
In parallel I also started to analyse what makes the wide-angle lens so special. Because it is not only the fact that this kind of lens enables to capture a broader area. Another important aspect are the noticeable distortions being an integral part of the wide-angle lens. Sometimes it adds something to the picture, sometimes the opposite. In the picture above the distortion is good visible in the upper part of the image and on the right side of it. Because there are the clouds and they are supposed "to flow" on the sky, the distortion emphasizes the effect, working well.
But be aware that it can work also against you:
This photo shows the so called 'ball apartments' in 's Hertogenbosch, The Netherlands. They are all, well, ball shaped. On the picture only those in the middle have the proper shape. The balls on the edges of the picture are distorted by the lens. I experienced that it is not always easy to deal with it in post processing. So be aware.
Playing with perspective
Wide angle lens has another interesting feature: it introduces a 'perspective distortion', so the objects closer to the lens appear bigger than the objects being more distant from the lens. The relative difference in size between close and distant objects is bigger than in case of regular lens (again, due to the distortions). This trick is used quite often in architecture photography. I have also tried it:
In both examples above the physical distances between foreground and background objects were not as big as it appears in the photos. And the first plane is made more dominant by an illusion of making it bigger. Again, sometimes it works, sometimes not.
Coming closer to the subject
Because of wide-angle one has possibility to get closer to the subject and still have it fully in the frame. This is sometimes advantageous; take a look at the following picture:
When taking this picture I could come so close to the cathedral that there was nobody walking in front of me.
But you see that this technique comes with the price: the perspective distortion are much more visible with the wide angle lens than with the other ones. Even a small tilt of the camera causes the vertical lines to incline dramatically. In the picture above it works because of the character of the building, but in the picture below perspective distortions make the picture actually unacceptably malformed:
But being able to get closer can make your picture:
Just to give an impression: here the lens was placed about 0,75 m in front of the wheels (which are about 2.5 meters high). Try to do it with a regular lens.
