Here's some verbiage that Capture One provides:
Capture One Pro 20 is an advanced and comprehensive photo workflow tool suiting a variety of applications from photo editing to tethering to asset management and organization needs. Version 20 of this esteemed software sees updates to core editing tools, including a Basic Color Editor, for a more streamlined and faster editing workflow. A dedicated High Dynamic Range function helps to achieve improved shadow and highlight response while enhanced Noise Reduction affords cleaner, clearer results for working with imagery shot at high ISO values. Faster editing is possible with an updated scrollable interface along with a "switch to next" function for quicker culling and sorting of files. This version also now supports DNG files and has updated keyboard shortcuts, the ability to copy both layers and masks between files, and an even cleaner interface for a more enjoyable working experience.
