Correcting For Lens Distortion

Taken from yesterday’s walk through Toronto’s burgeoning south core, here’s a demonstration of Lightroom’s lens correction capabilities.


In many cases, a byproduct of lens correction is cropping. This is particularly common in architectural photography as buildings appear to ‘shrink’ into the sky from the perspective of street level. In the first example (above), note the lateral cropping. In the second example (below), note the crop along the bottom, along with absence of pixels in the upper right corner as a result of the crop.

Composing from farther back would mitigate the crop because there would be less lens distortion. The problem is, that may diminish the impact of the subjects. The ideal solution would be to use a tilt-shift lens.
