Processing Engine

The processing method or engine determines the way in which a RAW file is demosaiced, color managed and presented on screen. Changes in engines can dramatically improve how the image is presented. The tools and their adjustments in Capture One can therefore produce different results depending on how they interface with the engines.

Introduction

The latest version of Capture One uses a revised process method that offers several image quality enhancements. Image variants that were edited and processed in older versions may therefore have a different appearance when upgraded to the latest version’s processing engine. Switch to the older process version if you need to reprocess image variants to achieve the same result for output. Access to previous versions of the processing engine is available from the global preferences dialog, see below.

Upgrade variants

Upgrading variants using the latest Capture One processing engine in the updated documents is optional but doing so provides improved image quality and access to the latest tools. Once updated, the settings cannot be reversed, however, individual variants may still be processed using previous versions of Capture One tools and processing engine, available in the global preferences dialog (see below for more details). Note user Presets and Styles may have to be fine-tuned to match the output of previously processed images.

A simple way to test the effect of new processing engines on images is to clone the variant (select image, right-click>Clone Variant) and upgrade the engine on the cloned image. That way you can then compare and contrast the two side-by-side before committing to the updates. See more information on cloning.

  1. Select individual images (i.e, variants) or select multiples using the Cmd/Ctrl key (Mac/Windows), or shift key, and clicking on the relevant images.
  2. From the Color Tool Tab, go to the Base Characteristics tool, and click on the Upgrade icon to the right of the Engine text field.
  3. A warning dialog opens with Cancel and Upgrade Engine options.
  4. Click on Upgrade Engine.
