For 80% of photographers (enthusiasts, real estate, events), this is all the RAW editing you need.
Windows 7 (SP1), Windows 8, Windows 8.1, and Windows 10 (64-bit editions).
While competitors like Lightroom force a catalog-based workflow that hides the user's files behind a database abstraction layer, ACDSee v20 embraces the Windows Explorer structure while adding a layer of intelligence (AI Face Detection) and professional editing tools (Channel Filtering/LUTs).
At the time of its release, ACDSee Photo Studio 20 v20.2 build 593 was often compared directly to Adobe Lightroom Classic. While Lightroom Classic had its own powerful AI tools for masking and selection, ACDSee Photo Studio 20 was noted to have an edge in the sheer number of editing options.
The 2020 version introduced several major technological shifts for the ACDSee ecosystem: ACD Systems ACDSee Photo Studio 20 v20.2 build 593
