Global Application Preferences

Preferences / Customization

Capture One Preferences enables customization of the application to help aid workflow.

Go to Capture One > Preferences [Mac] or Edit > Preferences [PC] to edit and personalize Capture One’s global applications preferences.

Adjust function of mouse scroll wheel. Other options include whether or not to open a new Session in a new window.

The background pattern and the color of the viewer can be adjusted to different shades of gray, white and black. The Capture One default is a dark neutral background.

The size of margins and the Local Adjustment Mask Color can also be adjusted here.

Go to Image Preferences to adjust the functionality or handling of different types of files.

The Cache slider can be adjusted to set the size of the proxy file. The higher the Preview Image Size, the higher quality of the Quickproof output recipe and preview image that Capture One generates. A large cache setting will, however, increase the amount of time it takes to load previews and thumbnails in the application.

Check mark one of the EIP Packing options if an .EIP workflow is preferred. EIP packing can be made automatically on import or capture (Phase One digital backs only).

Many users shoot both RAW and JPEG simultaneously. To avoid working on JPEGs and TIFFs remove the Editing option to ensure these files are viewable but not editable.

Metadata: When working in different applications, metadata will be stored in different ways. Choose your favored option. If no choice is made, the metadata entered in Capture One will be preferred to third party metadata. 

Choose a standard extension from Phase One digital back: IIQ or a Raw TIF files. The TIF extension is default as it is compatible with older applications. It is important to emphasize that the TIF extension is a RAW file not the TIF format known from e.g. Photoshop®.

Shutter Latency controls the timing between back and camera. Power Mode and Safe Mirror Up are both related to older Phase One backs.

The two remaining drop down menus in this section enables users to select a camera model when using a Leaf digital back and adjust the pause settings for Live Preview from 30 seconds to 20 minutes.

Remove the check marks from the Providers section to stop the automatic start of Capture One when the individual camera brands are connected to a computer.

Select an option from the Rendering Intent drop down menu. (Rendering Intent refers to the conversion of one color to another).

Perceptual (default)
Compresses the total gamut from one device’s color space into the gamut of another device’s color space when one or more colors in the original image is out of the range of the destination color space. This preserves the visual relationship between colors by shrinking the entire color space and shifting all colors – including those that were in gamut.

Reproduces the original image color saturation (vividness) when converting into the target device’s color space. In this approach, the relative saturation of colors is maintained from gamut to gamut. This render intent is primarily designed for business graphics, where the exact relationship between colors (such as in a photographic image) is not as important as are bright saturated colors.

Relative Colorimetric
When a color in the current color space is out of gamut in the target color space, it is mapped to the closest possible color within the gamut of the target color space, while colors that are in gamut are not affected. Only the colors that fall outside of the destination gamut are changed. This Render Intent can cause two colors, which appear different in the source color space, to be the same in the target color space. This is called “clipping.” Relative colorimetric is the default method of color conversion built into Photoshop 4.0 and earlier.

Absolute Colorimetric
Colors match exactly with no adjustment made for white point or black point that would alter the image’s brightness. Absolute Colorimetric is valuable for rendering “signature colors”, those colors that are highly identified with a commercial product such as the yellow used by the Eastman Kodak Company™, or the red used by the Coca-Cola Company™.

Set the values of exposure warning by adjusting the shadow and highlight sliders. When enabled in Capture One, areas that fall outside the set values will be shown by a color overlay.

By default the highlight warning value is 250 and the shadow warning is not enabled.
Double click on the highlight and shadow color area to change the overlay color. The default highlight color is red and the shadow is blue.

Adjusts the Crop tool preferences. Choose when to Show Mask, and adjust the Opacity and Brightness levels of the area outside the crop. There are also a range of selectable Frame, Labels and Grids options. It is also possible to change the color of a crop mask and guide line. 

The Focus Mask can be adjusted to increase and decrease the threshold setting for the preferred sharpness. The color (default is a lime green) and the opacity of the mask are also adjustable.

This tab will show the registered and unregistered Capture One applications. The frequency of how often Capture One should be checked for updates is also selectable here.

Capture One can register all Phase One products automatically or by prompt. Registering products will help support the development of future products and software features.

When an update is available it should be downloaded and installed on-top of the current installed application.


Choose if and when you want to be notified and when certain actions happen. Checkmark the boxes in the Files and Folders, Adjustments, Favorites, Options and Media Pro sections section to warn when, for example, you are about to permanently delete images.
