ACDSee, ACDSee Pro and ACDSee Free are image organizer, viewer, and RAW / image editor programs for Microsoft Windows and Mac OS X 10.6 and higher, developed by ACD Systems International Inc. ACDSee was originally distributed as a 16-bit application for Windows 3.0 and later supplanted by a 32-bit version for Windows 95. ACDSee Pro 6 adds native 64-bit support.
ACDSee's main features are speed, lossless RAW/image editing, image batch processing, metadata (Exif/IPTC), with support to edit/embed metadata in image files, rating, keywords, and categories, and geotagging/GPS support. Judging the image quality of a picture is fast due to next/previous image caching, fast image/RAW decoding and support for one-click toggling between 100% and fit screen zoom mode anywhere inside the image. For professional users most of ACDSee's features can be accessed via keyboard.
ACDSee displays a tree view of the file structure for navigation with thumbnail images of the selected folder, and a preview of a selected image. ACDSee started as an image organizer/viewer, but over time had image editing and RAW development (Pro version) capabilities added. The thumbnails generated by ACDSee are cached so that they do not need to be regenerated.
Unlike programs such as Adobe Lightroom, ACDSee only stores image metadata in its database. Lightroom stores the changes made to images in its database also, not affecting the files on disk. ACDSee's database can be backed up, and exported/imported as XML or binary.
The photo manager is available as a consumer version, and a pro version which provides additional features, and additional image editing capabilities. In 2012, ACDSee Free was released, without advanced features.
ACDSee Pro was released on 9 January 2006 to provide a software program for professional photographers. ACD Systems decided to separate its core release, ACDSee Photo Manager, into two separate products; ACDSee Photo Manager, aimed at amateur photography enthusiasts, and ACDSee Pro which would target Professionals by adding a new package of feature sets. ACDSee Pro’s development team is based out of Victoria, British Columbia and was originally led by Jon McEwan, and more recently by Nels Anvik, who oversaw ACDSee Pro 2.5 through to Pro 5. The original ACDSee software was created by David Hooper, who also added a number of features to ACDSee Pro, such as Lighting correction (formerly known as Shadows and Highlights) and Develop Mode (in version 2.0). ACDSee Pro is written in C++, with the interface built using MFC.
Version Pro 1.0
The first version was simply known as “ACDSee Pro”, without any version number. However, in the “About” box, it was identified as being “Version 8.0”, the same version number used in the ACDSee Photo Manager product released around the same time. Future versions of ACDSee Pro restarted the version numbers, beginning with 2.0. Its retail price was $139. The first version of ACDSee Pro included:
- Interactive and batch RAW processing (non-destructive RAW editing)
- Color management
- Patented Lighting and Contrast Enhancement (LCE) / single-exposure HDR (High Dynamic Range) technology, created by David Hooper (known as “Shadows and Highlights” in the product itself.)
- Image comparison tool for comparing multiple images, including their histograms and metadata.
Version Pro 2.0
ACDSee Pro 2 was released on 11 September 2007. It included a new demosaicing algorithm, which significantly improved the quality of RAW processing. Its new features included:

ACDSee Pro 2, 2.5, 3 and 4 all participated in a Beta program which incorporated feedback from users into the full releases.
In August 2012, ACD Systems released ACDSee Free, which retains all viewing features for the most common image formats (BMP, GIF, JPEG, PNG, TGA, TIFF, WBMP, PCX, PIC, WMF, EMF); it lacks a thumbnail browser, and support for RAW and ICO formats. A reviewer at BetaNews found it "fast, configurable and easy to use". The version runs on Windows XP or newer.
