Perspective correction comparison

Here are two versions of the same image, for comparison, both processed in PhotoLab. The first image has no perspective corrections. The second version includes horizontal and vertical perspective corrections using DXO's Viewpoint tool. I'm presenting this comparison for those who are either not familiar with perspective corrections, who own software that does not have that capability, or who think that perspective corrections are only intended for things like correcting converging verticals in architectural images. A number of other software packages have similar functionality including Lightroom, PhotoShop and ON1, among others. At first some of the corrections may not seem obvious, but after comparing various objects in both versions the differences become much clearer.

First rule of real estate photography - Verticals must be vertical

Not sure how your software works, but with mine I would be able to lean the top in to correct the verticle, which could mean not losing the side-table leg as yours has done.

How about showing us? Do you already know that as a fact?

mws, thanks for posting. This used to be quite difficult in the darkroom but LR makes it a snap and is very reliable. I usually apply it whenever appropriate and the viewer will never know. We all look like architectural photographers with tilts and swings now.

Even before applying the perspective tool is leveling. I have seen many good photos with tilted trees when a simple straightening tool does the job. Both are issues correctable with simple to use universal tools that too many photographers ignore.
It is well worthwhile to present examples like this post.

If they desire, everyone can learn to be more observant of their compositions. I still miss plenty in my own, though, so this topic is an excellent before/after how-to show n tell.Thanks again Mark!

Perhaps my vision is failing me but I do not see a big difference between those two images. I would be perfectly happy with the uncorrected version.
If the OP would be so kind I would certainly appreciate a brief explanation of what was corrected. Use a personal message if you will.
Addendum: I can see some correction on the lines of the ceiling. I was expecting something like barrel or pincushion correction.

I see a huge difference and how much better is the second one. And it doesn't appear that you lost very much real estate in the correction. I find in LR that I lose a lot of image when correcting, particularly when both vertical and horizontal corrections are necessary. Well done

This takes the "level horizon" concept a step further and considers the verticals as well as the horizontals in the overall image. I use this technique sparingly, but when I do, I find it is subtle but can be very impactful. Thanks for posting such a graphic example of this technique!
