Every time DxO comes out with a new version of DxO Optics Pro I spend some time with the trial version to see how the new version works. In the past I've never purchased it because it felt like it has a lot overlap with Lightroom and its user interface never felt right to me. This recent 6.5 version looks particularly interesting because of a couple of new features it has:
I've always thought that Optics Pro was trying to compete with directly with Lightroom. I'm glad to see that they've decided to focus on their strengths instead of a head to head competition with Lightroom.
I know many real estate photographers swear by DxO Optics Pro because of its automated processing capabilities and it's quality distortion correction. Automated post-processing can save you a bunch of time if you can integrate it into your workflow.
The feature that caught my eye in this version was the ability to do pseudo-HDR by making use of the fact that most RAW files contain several stops above and below the 0 EV value of the file. This is a technique that is handy to get better sky exposure for exterior shots and get a better window exposure when the view really matters.
Optics Pro is 30% off ($199 for the Elite version, which you need for most DSLRs) between now and Dec 25 so if you've considered DxO Optics Pro as a post-processing tool this is a good time to evaluate it and see if it's right for you.
