Session Users Glossary


An album allows the user arbitrarily create collections of images. Drag and drop images into an album from the Browser. Albums are virtual, meaning they only contain references back to the file. Therefore the same image can exist in many albums. 

Albums are typically used to create collections of favorite images, cull from larger groups or create subsets for further filtering. Any edits applied to an image in one album will be reflected in all other albums that contain the same image.


An album contains a fixed number of images. Drag and drop images into an album from the browser


Export converts the variant to a final file (e.g. Tiff or Jpeg). It has, ultimately, the same function as "Processing". For Express users, Export is the only option to convert to final file. Pro users can use either method.


A Favorite is a marker for a folder in a Session workflow. It enables quick and easy access to that folder via the Favorites area of the Library and tells Capture One to include the contents of that folder when searching.

Unlike a Catalog, a Session needs to know which folders to search when using Smart Albums. By marking a folder favorite you also make the contents available to the Smart albums (and only these folders).

A Favorite Folder enables quick and easy access to a folder in a session

Hot folder

If Capture One does not provide tethered support for a camera, it is possible to shoot tethered using a camera's proprietary software and a Hot Folder. A Hot Folder, in essence, will make Capture One auto select the newest images added to a (capture) folder.


The term Processing is inherited from the days of exposing photographic paper and chemically processing the image in a darkroom. It is used in this context to describe the conversion process from the "negative" (RAW) to a "print"  (e.g a Tiff or Jpeg). For the purposes of comparison it is the equivalent to Export. Processing, however, is more powerful than Export, and with a number of unique features.


The Selects Folder (previously known as the Move-To folder) is automatically created when a new session is started. It is designed to enable users to quickly and easily move image files when culling a shoot. Once an image is selected, users simply need to press the 'move to selects' button on the toolbar (or use the shortcut) and the location of the file will change to this assigned folder.

Sessions are designed to handle single project and are favored for tethered workflow. A Session in its basic form is a template of folders nested in a top folder. Interface into the session is based around a simple file browser concept. The folders in the session are assigned actions by default, for example the Capture folder is assigned to the folder named "Capture", so plugging in a camera and shooting will automatically write images to this folder. 

Settings and previews for files in the session folders are stored locally to the folder of RAWs in a sub folder called "CaptureOne". A Session can easily be moved to another computer or another physical disc drive. As all necessary files are saved inside the Session folder by default, you can work on the entire Session from any computer.

Sessions enables you to store all files as a complete project that includes RAW files, setting files, library files, output files and paths to drives used in a project

Smart album

A Smart Album is populated with images based on set search criteria. It is a virtual album, meaning it is only referencing images from other collections that meet that criteria. A Smart Album can (for example), search for all 5 star images in the catalog or session. Its contents will change if you add or remove 5 star images from images in the search. In a Session, all folders that are favorites will be searched by Smart Albums. When in a Catalog, Smart Albums will search the entire catalog, unless nested in a Project.

A Smart Album only contains the references and adjustments that will be applied to all views of the image

Session folders

Sessions Folders form part of any created Session. They are shortcuts to the current active Capture (small camera icon), Output (cog icon), Selects (small looping arrow icon) and Trash (trash can icon) folders for the Session. To see the current active folders, right click on a session folder and then select "show in system folders"

By right clicking on another folder in the library and choosing "set as", these functions can be moved. The Session folders will then represent a shortcut to the folder chosen by the user.


Sessions Folders are created as part of Session. They include the Selects, Ouput, Trash and Capture Folder


Attaching a camera to the computer via a cable and shooting images directly to the hard drive instead of memory card. Images are shown on screen as soon as they are on the hard drive.


Tokens (also refereed to as Dynamic locations when used with import and output) are variables which extract some metadata from the file and use it to make up the naming structures of elements in the workflow. Depending on the tool used Tokens can be used to automate folder structures or name images.


A variant is used to describe an image in the browser that is somewhere between the RAW file and the final processed file. As Capture One is a non-destructive editor what is shown on screen is effectively a preview/render of the RAW plus adjustments before conversion to the final file.
