When comparing Capture One Pro vs Paint.NET, the Slant community recommends Capture One Pro for most people. In the question“What is the best photo editing software?” Capture One Pro is ranked 9th while Paint.NET is ranked 12th. The most important reason people chose Capture One Pro is:
Capture pilot is a feature that allows any web-enabled device to remotely connect to Capture One and use a subset of its functionality like view a selected catalogue, rate images and even make minor edits to photos. An iOS app for Capture Pilot is available as well that in addition to default functionality also allows controlling a tethered camera though that functionality has to be purchased separately.

Capture pilot is a feature that allows any web-enabled device to remotely connect to Capture One and use a subset of its functionality like view a selected catalogue, rate images and even make minor edits to photos. An iOS app for Capture Pilot is available as well that in addition to default functionality also allows controlling a tethered camera though that functionality has to be purchased separately.
Pro Well thought out tethered capture implementation
Once you hook up your camera to Capture One, the program offers a bunch of useful tools and workflows based on your needs.
For example, it has Composition Mode that allows setting up the shot without taking up hard-drive space by replacing the last image taken with the a one as soon as you take it. It has Hot Folder functionality that will keep an eye on changes in a set folder and as soon as any new images appear in that folder they will be added to Capture One; great for cameras that are not supported by Capture One natively and unlike other Hot Folder functionality in other programs C1 captures everything coming in quickly and imports all images as active. Many cameras can be controlled via the program and if the camera has live view, similar functionality can be enabled in Capture One. Plus, live view allows superimposing an overlay; great for cover shooting. There's also a overlay mask that shows wether a shot is in focus or not. And many other functions and design decision that help with ease of use.
Pro Extremely robust color editing
A huge amount of color editing options, with the ability to modify overall, to extremely targeted ranges. Especially robust support for editing skin tones.
Pro Clean and sharp default processing
Straight imports seem a bit sharper and more dynamic than many other RAW editors.
Pro Very intuitive Irs, easier to use and raw conversion using Sony seems better
Pro Easy to learn and use
Unlike most photo editing software, Paint.NET is simple to learn and easy to use. This means less time is spent learning the in's and out's of Paint.NET and more time on photo editing. For those who only edit photos sporadically and don't have time to invest in learning complicated tools for editing, Paint.Net will suit your needs.
Pro Free software
There is no charge for this software; but donations are welcomed.

Pro Lightweight
Paint.net provides a streamlined but effective core tool set. Support for advanced and niche features is provided through modular plugins, allowing the user to install only what's needed.
Pro Actively developed
The project is active and being continually expanded and refined.
Pro Active and friendly community
The forums are filled with tutorials, as well as people who are friendly and eager to help.


Pro Plugins allow extra functionality
Plugins can be made by anyone in the community, and are offered for download on the forum. They extend the capabilities of Paint.NET to cover most tasks.
Pro HiDPI support
Paint.NET supports fully HiDPI displays, with no scaling problems.
Cons
Con Expensive
Has hefty price tag, although both license and subscriptions are on offer.
Con Doesn't support color checkers
Unfortunately, there's no way to create color profiles using the Color Checker Passport.
Con Asset management could be better
While it does have asset managment, it isn't as robust or intuitive as some of the competition, like Lightroom in particular.

Con Only available on Windows
Paint.NET is only available on Windows.
Con No project-based interface
You can only edit a single image at a time in Paint.NET. For example, in other tools you can open 5 or a 100 images at the same time, and stack those windows in all directions.
Furthermore, when you are editing in Paint.NET you can only "view" a single image at a time, even though you can have multiple images open. This limits your zooming ability, as the image will go fullscreen quite quickly, and hide parts of it behind the floating toolbars which can not be embedded anywhere on the screen.
