The first and most obvious implementation of the new Capture One AI masking capability is in the Layers palette with two new buttons labelled ‘Subject’ and ‘Background’. If you use either of these, Capture One will attempt to identify the main subject in an image and mask it (or the background).
This has worked reasonably well on the image of the boat above, but is a little hazy around the edges and has included areas of the backgrounds seen through the boat’s awning. The Background button simply creates an identical but inverted mask.
It’s a good start and will no doubt work better on some images than others, but there’s a bit more to Capture One’s new AI masking than this, and it’s the AI Select tool.
Capture One AI Selecting objects and areas to mask
From now on you can simply move the mouse pointer over areas of your image and Capture One will show a read overlay over the mask it will create if you click. There’s no option for selecting skies, as such, as there is in Lightroom, but it seems to have identified the sky area pretty well anyway.
