DxO PhotoLab (was DxO Optics Pro) provides a complete set of smart assisted corrections that you can manually fine-tune at any time. Take control on every aspect of your photos: effectively remove noise, get rid of light constraints, recover color details, apply sophisticated optical corrections, and enhance details.
Integrity Pro builds on Integrity Plus. It has the new v8 crawling engine, it checks links and generates a sitemap with all the searching, filtering and exporting functionality of the Plus version. It adds SEO details and a sitewide spellcheck. It isn't intended to replace Scrutiny, but to be pitched between Integrity Plus and Scrutiny, a more affordable step for Integrity Plus users. There will, of course, be an upgrade from Integrity Plus, but this early public beta is simply free until the stable version is released.
