Global Application Preferences

Preferencias / Personalización

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

Verifying and modifying the preferences

Capture One has a range of preferences that allow you to alter how a particular feature responds. In some cases, certain features can only be accessed from the preferences window, so it makes sense to spend some time becoming familiar with each tabbed page and specifying the preferences to suit your particular workflow. The settings affect all Catalogs and Sessions within Capture One.

  1. Go to Capture One > Preferences (Mac) or Edit > Preferences (Windows). The global Preferences window opens. 
  2. The settings are arranged by page using labeled tabs. Click on a tab to view and specify the settings to suit your particular need.
  3. To enable the new settings, quit Capture One and restart. Restarting is not necessary when adopting certain features, such as Calibrating an Eizo Monitor, or changing the Color Wheels Layout.
  4. Each page can be returned to their default settings independently of the others. Click on the Defaults button on the relevant page, then quit Capture One and restart.


Select General settings relating to the Viewer, Catalog and Session, Recent Captures Collection, Importing, Hardware Acceleration (Use OpenCL), Activities, Favorites, Catalog Backup, Media Pro, and Tangent Integration.


Enable or disable the mouse scroll wheel to zoom into images displayed in the Viewer.

Catalog and Session

Open a new Catalog or Session in a new window in addition to the current open window. Deselect this check box to replace the current window with the new Catalog or Session.

Recent Captures Collection

Choose the duration after when a Recent Catpures folder will be created in the Library. This is useful to isolate groups of images when shooting tethered throughout the day. Select the duration from the fly-out menu.


When detecting a memory card in a card reader, choose between whether the importer dialog opens automatically, or ignores it.

Hardware Acceleration (Use OpenCL for)

Choose Auto from both the Display and Processing drop down menus to improve performance. The Auto setting will automatically determine whether your graphics card will produce a faster performance than the CPU (Central Processing Unit) in your computer. Select Never if you are experiencing stability problems. Note, OpenCL stands for Open Computing Language.


Enable or disable the activities icon, when Capture One is busy.


Choose the appropriate action for adding Session Folders to Favorites from the fly-out menu.

Catalog Backup

From the Remind on close fly-out menu, select the frequency for backing up Capture One catalogs based on the volume of work. Backup Catalogs do not contain any source (i.e., original) image files, whether referenced or stored internally.

The Location field displays the path to the current backup location. Click on the arrow icon to verify the setting. The default location for backing up catalogs is in the User’s Application Support folder in the Library (Mac), however, where possible, back up to an external disk is recommended.

Media Pro

When importing Media Pro catalogs, metadata and Catalog Set information from Media Pro can be used by Capture One to update image variants and Albums, respectively. Select the intended action for each, as desired.

Tangent Integration

Capture One’s interface and the majority of the tool set can be controlled by grading panels from Tangent. Each Tangent panel model is supported by Capture One Pro with a group of default control layouts. Enable support by checking the box.

To reset only the displayed settings, click the Defaults button at the bottom of the tab.

Select General settings relating to the Viewer, Catalog and Session, Recent Captures Collection, Importing, Hardware Acceleration (Use OpenCL), Activities, Favorites, Media Pro, Catalog Backup and Tangent Integration



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 proof margins can also be adjusted here.

Local Adjustments

The Local Adjustment Mask Color can be altered. Click on the icon and select the color from the dialog.

The background pattern and the color of the viewer can be adjusted to different shades of gray, white and black


Modify the functionality or handling of different types of files.


The image preview size (px) value 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. Preview sizes of 3840 px and 5120 px have been added to improve the interactive performance of the preview image when applying adjustments on UHD/4K and 5K screens. The 3840 px setting is also recommended for DCI 4K (4096 x 2160 px) displays.  A large cache setting will, however, increase the amount of time it takes to load previews and thumbnails in the application.

EIP Packing (Sessions only)

Check mark one of the 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 accidentally, remove the editing option to ensure these files are viewable but not editable. The effect of selection is immediate, Capture One does not need to be relaunched. When editing is disabled, JPEG, TIFF and PNG files can still be imported with their corresponding variants rendered and displayed in the browser and viewer. Note, however, when the variants are selected the editing tools are grayed out.

Make new files writable by everyone: When selected, new files (created during import, capture or EIP conversion) will have write permissions for everyone, not just the file owner.

Default Processing Engine: Select the default processing engine for Capture One from the fly-out menu. The processing version selected will only be used by new files (created during import, capture or EIP conversion), existing files rendered with later versions will remain unaffected. You can check the processing version used to render selected variants in the Base Characteristics tool, located under the Color Tool Tab.


When working in different, third-party applications, metadata will be stored in different ways. Choose your preferred option. If left to the default settings, the metadata entered in Capture One will be preferred to third-party metadata.

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

Capture Pro

Phase One and Leaf Credo Configuration

From the Extension fly-out menu, choose between IIQ or TIF, when tethered and saving files to the computer. The IIQ extension is the default setting, however the TIF extension is compatible with older applications. It is important to emphasize that the TIF extension is a RAW file like IIQ, not the TIF format known from Photoshop®, for example.

Leaf Aptus and Aptus II Configuration

When using a Leaf digital back, select the support applicable for your camera by model. If the list is not showing, select Leaf Credo under  Providers/Enabled Tethered Support (Mac/Windows), below.

Live Preview

Adjust the pause setting for Live Preview from 30 seconds to 20 minutes.

Providers/Enabled Tethered Support (Mac/Windows)

Select the appropriate support for your camera by brand. Capture One will automatically detect a supported model once connected. To prevent possible conflict between Capture One’s drivers, deselect the other brand options. Phase One industrial users adopting the Phase One SDK to capture should de-select support for Phase One cameras.

From the Extension fly-out menu, choose between IIQ or TIF, when tethered and saving files to the 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.

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 Rendering 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.

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™.

Saturation: 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 rendering 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.


A number of Eizo ColorEdge CG monitors with a built-in calibration sensor can be re-calibrated from within Capture One.

The following Eizo monitor models are supported:


CG245W, CG246, CG247, CG247X, CG248 (UHD 4K)


CG275W, CG276, CG277


CG318 (DCI 4K)

Color Wheels Layout

Capture One’s color wheels used in the Color Balance and Color Editor tools located in the Color Inspector can be displayed with the chroma hue reference phase rotated 90-degrees to imitate a Vectorscope layout. Select the layout as appropriate. Capture One does not require restarting.

Select an option from the Rendering Intent drop down menu.


Exposure Warning

Set the values of the Exposure Warning function by clicking and dragging the shadow and highlight sliders, as desired. When enabled, 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 icons to change the overlay color. The default highlight color is red and the shadow is blue.

Levels Tool

The Channel Mode allows you to switch between the relevant shadow and highlight pickers for the default combined RGB channel mode and separate red, green and blue channels.

Preset output Target Levels for both modes can also be applied by clicking and dragging the appropriate sliders.

The Auto Levels Clipping Thresholds sets a 0.10% threshold for Shadows and Highlights by default. This allows a small number of pixels, for example specular highlights, to clip without reducing the overall contrast and dynamic range of an image. Type in the values to alter the settings. The range is adjustable between 0-10%, although in practical terms it’s unlikely that anything approaching 1% and above would be necessary. Note, the Auto Levels Clipping Thresholds deliver the specified percentage of clipped pixels precisely.

Click the Defaults button to reset the settings. 

Set the values of the Exposure Warning by adjusting the shadow and highlight sliders.


Modify the behavior of Crop tool.


Choose when to Show Mask, and adjust the Opacity and Brightness levels of the area outside the crop. There are also a range of Frame and, Label options.

Grids and Guides 

There are number of options to alter the grid and guides tools. You can also change the color of a crop mask and guide line.

Focus Pro

Focus Mask 

The Focus Mask tool is used to evaluate whether an image was sharp at the time of capture, and does not depend on the image settings. However, you can alter the threshold or level at which the Focus Mask will be triggered. To assess sharpness more critically, the threshold should be increased above the default 250 setting (i.e., the slider dragged to the right). The amount will vary by use case, however the threshold slider can be adjusted while observing the effect in the Viewer. The color (default is a lime green) and the opacity of the mask are also adjustable.

Warning! While this is a useful tool to evaluate the sharpness of a capture initially, to assess critical sharpness you should check images in the Viewer or Focus tool at 100% magnification.

The Focus Mask can be adjusted to increase and decrease the threshold setting for the preferred sharpness


Choose if and when you want to be notified and when certain actions happen. Check mark the boxes in the Files and Folders, Adjustments and Output sections to warn when, for example, you are about to permanently delete images.

It is not recommended to disable the Warn when deleting images from disk dialog. Images cannot be recovered.



This page displays registered and unregistered Capture One applications. The frequency of how often Capture One should check for updates is also selectable here. When an update is available it should be downloaded and installed on-top of the current installed application.

Product Registrations

Capture One can register all Phase One products as well as other supported camera models, either automatically or by prompt. Registering products will help support the development of future products and software features.
