As a photographer, you may encounter issues occasionally when navigating Kelvin. In this article, we will outline the most frequently encountered issues and how to resolve them. If this article does not cover the issue you're encountering, please reach out to our support team for further assistance.
Stale Thumbnail
From time to time you may notice that despite exporting a new file from Capture One, the thumbnail in Kelvin does not update to reflect the change. The following article will cover how to ensure thumbnails are updating as expected.
The thumbnails are rendered based on the filename. When a file is originally sent to the Kelvin Watch folder, Creative Force will cache the data that we see in Kelvin from what we can see on the file in the folder.
If a new version is sent to the folder with the same filename, the changes will not be reflected on the thumbnail in Kelvin as the system will still be reading what was on the older version of the file that we originally cached. To fix, you can update the thumbnails by exporting the image(s) with a new filename.
Deleting Kelvin Working Folder
Sometimes, you might run into a scenario where Kelvin appears blank and there are no actions available. The issue typically takes place because part of the Kelvin ‘working’ folder has been tampered with, or corrupted. Kelvin uses a dedicated Working Folder as a "home base" for storing temporary files and configurations.
To work correctly, the Working Folder must have full write access and avoid using cloud or network storage. The ‘Working’ folder is where Kelvin stores some data and images after they have been transferred to Gamma (Our Web App).
When you first install Kelvin you define where the working folder will be:
But the fix is relatively easy. You will need to find the Kelvin Working Folder, delete it, and then restart the computer. Then when you open Kelvin again, it will rebuild the working folder.
Setting Up a New Working Folder
Follow these steps to set up a dedicated Working Folder:
Create an Empty Folder: Ensure the folder:
Is empty.
Is located on your local hard drive (not on cloud or network storage).
Is in a location where you have full write access (e.g., Desktop or Documents).
Configure Kelvin:
Close Kelvin.
Open the application settings when you restart it.
Click the folder icon next to "Working Folder" and select the new, empty folder.
Save your changes and restart Kelvin. This prevents conflicts caused by using a project folder as the Working Folder and ensures Kelvin has a stable environment for operation.
Additionally, verify that your security software is not blocking Kelvin from writing to this folder and ensure you have appropriate permissions (antivirus or firewall settings, for example).
On Mac OS
You can search on Finder for "Kelvin", then delete that entire folder. Alternatively, you may have defined it as something slightly different in your Workspace setting (See above).
Within the folder it should look a little like the below:
Alternatively, you can search in finder for ".studio" and work back from there to delete the main Kelvin folder:
Once you have located the correct folder, you will want to delete that entire folder, then restart your computer, and open Kelvin. Kelvin will then rebuild the working folder and it will no longer be corrupted.
On Windows
On Windows, the workspace is automatically defined and named Kelvin Workspace. You can create the folder path differently than what is shown below.
To find the folder, you can search for ‘Kelvin Workspace’ either in the search box in your taskbar or in file explorer.
Notes:
Always use a dedicated folder for Kelvin's Working Folder rather than a project folder.
Avoid storing the Working Folder on external drives, network storage, or cloud-synced locations.
Periodically check the folder for any accidental additions that might interfere with its functionality.
