Exploring Lightroom 5's Perspective Correction

An interesting picture of one of Jakarta's main streets - Jl. Jend. Sudirman at right at peak hour. So I used a 10 stop Neutral Density filter, so the busy cars zipped by (slowly), leaving only bare trace of light trails.

And as I used a 16mm lens, you'll see the lens distortion - buildings aren't upright. And you'll need photoshop to correct it.

However, since the release of Lightroom 5, a new feature is the perspective correction - which I tried. So the "Auto" turns out like this:

Not too bad - the buildings are more or less upright, but maybe a little to much as the top looks bigger than the bottom.

There is a "Full" perspective correction, which makes the picture like this:

So.... not always turns out well.

Summary: It's a useful little feature, which is a one click adjustment. Works out some of the time - whether "Full" or "Auto", try and experiment to see which turns out better, or which you like better.
Is it worth an upgrade to LR5, if you have say LR 4? Prob not. But if you have it, use it.

Keep Shooting!
