We're talking about this tool. Here's the official presentation.
I extensively tested the new tool on the day of its official announcement (October 23, 2024). Since there was no urgency, I took my time to test it further and observe it carefully. Here are my thoughts on the tool.
AI Support
It bothers me when the term AI is used excessively. For me, intelligence also means learning and improving over time, not just running a routine thousands of times to achieve the best possible results. Face detection, for example, is based on patterns. This has nothing to do with intelligence as I understand it.
Be that as it may: The interesting thing about the Match Look tool is that it works with existing sliders and therefore allows us to make comprehensible adjustments afterward. So far, so good.
Expectations
My expectation was that the new tool would use artificial intelligence and RAW information to essentially re-expose and manipulate an existing image to achieve a different look. However, this is still future music in Capture One and not achievable with Match Look in any way.

I tested it with images from my colleague Stefan Rappo on a photo I took in Ibiza. What can I say? Does my image now have a Stefan Rappo look? Certainly not!

Match Color in Photoshop
The Match Color function has existed in Photoshop for about two decades. It practically never works as one would hope, making the tool useless for me. You cannot simply transfer the colors from one photo to another. It's not that simple, as shown in this example.


Who is Match Look for?
Match Look from Capture One is certainly better than Match Color in Photoshop. But you need to understand exactly what it's designed for.
It's essentially an improvement of the earlier Smart Adjustments tool. An extension with more sliders and more control. Unlike what the name would suggest, it doesn't allow you to copy the look of external images onto your own images.
This isn't possible, and honestly, this is a relief for me. Isn't it great that not even AI can simply replicate a certain look? At least not yet. It shows me that there's much more to a specific look. After all, it's primarily about lighting, and not every scenario can be copied 1:1. A color table, contrast adjustment, and exposure aren't enough here. Even the thought of being able to move a photo to a neutral level in the first step is overthinking it. It simply doesn't work that way.
What the tool is good for
When Match Look is used correctly, it's quite suitable for images from a single shoot session. For creating a series of images and as another tool in the palette to create a starting point for a consistent look. You choose one (or several, which is great!) exemplary suitable images and then let Capture One adjust the look accordingly.
I tried this with a series I shot with Bianca. Morning by the sea in Tenerife. Afternoon with clouds in the mountains. The light is extreme in both cases. Once with black sand and rising sun. The other time with muddy cloudy sky. Both times the lighting mood is different, and the skin tones vary accordingly. Adjustments are essential here if both photos should fit well in a series.

The Match Look tool does a pretty good job here. I wanted to match the left standing photo to the image with the sauna. A few clicks led to a good result. I only had to reduce the saturation slightly in the example and apply the look at 80%. Then I was satisfied.

However, I still refined the color grading in Photoshop with my LUT SB Blockbuster. The images then fit even better together I believe.

Conclusion
Too bad — or not? — but in my eyes, Match Look really isn't a game changer. Too many sliders are used for colors, which makes it difficult to track changes. And for experienced users like me, Match Look isn't necessary as a starting point in the workflow either. Maybe this is different with landscape photography.
But it's still nice to see software development continuing to progress. That's why I keep following the innovations with great interest, and subsequently testing them thoroughly myself.
