A tilt-shift lens is essential to getting lines and perspectives straight in architectural photography. Its main feature is the ability to shift up or down without changing the plane of the camera to the subject. If a photographer tilts their camera back to include more of the sky or building the image will end up with converging verticals, sometimes referred to as keystoning.
Here are some images that demonstrate the lens' capabilities for shifting up or down. Additionally, since this lens is a TS-E II, the lens can be rotated in the mount to allow for left/right shift without rotating the entire camera body. In most of these, the subject is much higher or lower than my camera and a normal lens would not be able to produce this type of shot.
©2013 Lisa Bond Photography, this particular image is a great example of what this lens can do. The only way to get this shot of the lock would be to dangle off the bridge with some kind of rappelling equipment or super trusty rope and assistant. Fortunately I was able to get it with the TS lens and my feet planted firmly on the ground.
Some photographers resort to using perspective correction software with a regular lens which is an option and I have used it in the past. However, it is always advantageous to get the image correctly in the field whenever possible to minimize post production work and any unforeseen issues that may arise after you've left the location.
I am using a Canon 24mm TS-E II. Thanks for stopping by and I hope you are enjoying the warmth of summer!
