ACDSee Photo Studio Ultimate is a Windows photo application from ACD Systems that combines a photo library manager, a non-destructive RAW editor and a layer-based image editor. It is meant for photographers who want to sort, tag, find and edit large collections in one program. It is paid software, sold as a one-time perpetual license or through the ACDSee 365 subscription, with a free trial.
Work is split into modes: Manage for browsing and organizing, Media for the catalog database, View for single files, Develop for non-destructive adjustments, Edit for pixels and layers, and People for named faces.
Browsing folders and building a catalog
ACDSee Photo Studio works on the folders already on the drive. Photos stay where they are. The program records their metadata in an ACDSee database as users browse and catalog folders.
Folders open as tabs, and image baskets gather files from anywhere on the drive. Users can browse Dropbox and OneDrive folders too. Media mode shows only cataloged folders. Users can sort, group and filter files by ACDSee, EXIF and IPTC metadata.
Tagging photos and finding them again
Photos can carry ratings, tags, hierarchical categories, color labels, keywords and map locations. ACDSee keywords and categories sync with IPTC fields. Users can embed them in the files so other programs can read them. Quick Search returns results right away, while Advanced Search combines AND/OR conditions across metadata fields.
AI keywords and visual similarity
AI Keywords scans images and assigns keywords for what they contain, so a search for “beach” can find photos never tagged by hand. AI Image Similarity indexes photos by appearance. Selecting a photo finds related shots. Users can group look-alike images across folders or search results.
Faces and People mode
Face detection finds faces, and the user names them. Once users confirm some names, ACDSee Photo Studio suggests matches for other faces. Users can accept or reject these in batches.
Culling and stacking shoots
Auto-Stack groups photos by GPS location, capture time, visual similarity or a mix of these. Stacking only changes the display; nothing is deleted or merged. The Reject tag marks blinks and blurred frames so users can clear them all in one pass. A duplicate finder compares files across folders.
Batch tools rename files with templates, resize, crop and add watermarks. Panorama stitching, HDR merging and focus stacking are also available.
Develop mode for RAW files
Develop mode stores adjustments as instructions instead of changing pixels. Users can change or remove any setting later, and the original stays untouched. ACDSee Photo Studio Ultimate reads RAW files from more than 750 camera models.
Global controls include exposure, white balance, curves, color wheels, clarity, dehaze, noise reduction and lens correction. Light EQ brightens areas that are too dark and darkens areas that are too bright without shifting the rest of the image.
Users can paint local changes with a brush or apply them through linear and radial gradients. AI Subject, Sky, Background and Object tools build masks from a rough outline. AI Develop Presets analyze each photo in a batch and set adjustments per image rather than copying identical values.
Layered editing in Edit mode
Edit mode supports layer masks, adjustment layers, blend modes, layer effects such as shadow, glow and bevel, and auto-align and auto-blend for burst sequences. Frequency separation splits texture from tone for retouching.
Pixel tools include heal, clone and Smart Erase, which fills removed areas from surrounding content. Users can record edits as actions and replay them on batches. For portraits, AI Face Edit uses sliders to adjust facial features, while AI Hair selects hair for masking.
Generative AI and local AI tools
Four generative tools run in the cloud inside the layer workflow. AI Image Generation creates an image from a text prompt, a preset effect or reference images. Generative Fill adds missing detail to a selected area. Generative Edit changes a photo from a plain-language instruction. AI Remove erases unwanted objects.
These four tools use AI credits and show an estimated cost before running. The perpetual license includes a starting credit allowance, and the 365 plan refills credits monthly. Users can buy more credits. Other AI features, including denoise, super-resolution, keywords, face recognition, similarity search, sky replacement and AI selections, run on the computer without credits.
Perpetual license or ACDSee 365
The perpetual license of ACDSee Photo Studio Ultimate covers one device. The ACDSee 365 subscription includes the same photo management and editing, plus installation on up to five devices. It also includes upgrades to new releases, cloud storage, monthly AI credits and video editing software. ACD Systems also sells Photo Studio Home and Professional as separate Windows editions, and Photo Studio for Mac as a separate product.
Getting photos in and out
ACDSee Mobile Sync sends photos and videos wirelessly from an iPhone or Android device after scanning a QR code on the monitor. Users moving from Photoshop or Lightroom can point the program at their existing folders without a separate import step.
