One photo in two versions. I processed these similarly with two different applications and am posting them to show the differences. The obvious difference is the way the applications correct the lens; DxO--probably predictably--makes a greater effort to flatten the photo, because DxO's mission seems to be removing lens distortions.
For the most part I agree with DxO about the distortions. But I'm not so sure about this specific photo.
The color profiles differ slightly, too. A slight part of that difference might be my processing; the tools I used to sharpen the focus are dissimilar.
