Black and white negatives scanned in grayscale are not immediately editable in Capture One. Is it possible to change that?
1. Before importing images in Capture One, make sure that those are of the supported file format.
2. Note that TIF/JPG/PSD/PNG files that are not in RGB color space cannot be adjusted in Capture One and will be read-only.
3. Make sure that the color profile is assigned to an image before importing it into Capture One. On Mac, open an image in the default application Preview and select Tools -> Assign Profile from the main menu and make sure that RGB is selected.
