ACDSee was originally distributed as a [16-bit application](/source/16-bit_application) for [Windows 3.0](/source/Windows_3.0) and later supplanted by a [32-bit version](/source/32-bit_application) for [Windows 95](/source/Windows_95).[2] ACDSee Pro 6 adds native [64-bit](/source/64-bit) support. The newest versions of ACDSee incorporate modern Digital Asset Management tools like Face Detection & Facial Recognition (Ultimate 2019). ACDSee's main features are speed, lossless [RAW](/source/Raw_image_format) image editing, image batch processing, editing [metadata](/source/Metadata) ([Exif](/source/Exif) and [IPTC](/source/IPTC_Information_Interchange_Model)), rating, keywords, and categories, and [geotagging](/source/Geotagging). The image quality can be assessed quickly due to next/previous image caching, rapid RAW image decoding, and support for one-click toggling between 100% and fit screen zoom mode at any point within the image. Most of ACDSee's features can be accessed via [keyboard](/source/Computer_keyboard). ACDSee displays a [tree view](/source/Tree_view) of the file structure for navigation with [thumbnail](/source/Thumbnail) images of the selected [folder](/source/Folder_(computing)), 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](/source/Cache_(computing)), so that they do not need to be regenerated, and stored on disk as a database.[3] ACDSee's database can be backed up, and exported/imported as [XML](/source/XML) or [binary](/source/Binary_file). Each database and its associated thumbnails can also be loaded and saved as separate entities. The photo manager is available as a consumer version, and a pro version which provides additional features,[4] and additional image editing capabilities.[5] In 2012, ACDSee Free was released, without advanced features.[6] ACDSee is pronounced the same as [AC/DC](https://en.wiktionary.org/wiki/AC/DC). ## History ACDSee was first released in 1994 as a 16-bit application for [Windows 3.1](/source/Windows_3.1). In 1997 32-bit ACDsee 95 was released for Windows 95. 1999 saw the release of ACDSee 3.0. Version 5.0 was released in 2002, and 7.0 in 2005.[7] Development of this line continues, with version 20.0 released in 2016. This early version of ACDSee is sometimes known as ACDSee Classic or ACDSee 32. ACDSee Pro was released on 9 January 2006 aimed at 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](/source/Victoria%2C_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++](/source/C%2B%2B), with the interface built using [MFC](/source/Microsoft_Foundation_Class_Library). ## Free version In August 2012, ACD Systems released ACDSee Free, which retains all viewing features for the most common image formats ([BMP](/source/BMP_file_format), [GIF](/source/GIF), [JPEG](/source/JPEG), [PNG](/source/PNG), [TGA](/source/Truevision_TGA), [TIFF](/source/TIFF), [WBMP](/source/Wireless_Application_Protocol_Bitmap_Format), [PCX](/source/PCX), [PIC](/source/PICtor_PIC_image_format), [WMF](/source/Windows_Metafile), [EMF](/source/Windows_Metafile#EMF)); it lacks a thumbnail browser, and support for RAW and [ICO](/source/ICO_(file_format)) formats.[6] A reviewer at BetaNews found it "fast, configurable and easy to use".[6] The version runs on [Windows XP](/source/Windows_XP) or newer.[8] The product was discontinued in August 2013.[*[citation needed](https://en.wikipedia.org/wiki/Wikipedia:Citation_needed)*] ## See also - [Comparison of image viewers](/source/Comparison_of_image_viewers) ## References 1. **[^](#cite_ref-1)** ["ACD Systems Ltd. - ACDSee16 - Changes"](https://web.archive.org/web/19980201151243/http://www.acdsee.com/acd/acdc16ch.html).
