I am really happy with the addition of adjustable output sharpening and the proof functionality.
Does anyone know what goes into the "Diffraction Correction" checkbox under the lens correction tab? I do not see any difference on the images I tried it on. However, they were shot with wide-open apertures. I wonder if it only kicks in at smaller apertures registered in the EXIF data.
EDIT:
From the Capture One 10 documentation:
Diffraction correction
Diffraction effects lower the resolution of lenses at small apertures. Selecting this option helps mitigate the effect using a sophisticated deconvolution algorithm to sharpen the image and restore some of the fine detail that was lost during capture. The feature is not enabled automatically, it is processor intensive and when the time comes to export images it can extend processing times. Enabling this tool and the application of Sharpness Falloff correction can be considered the first stage in capture sharpening.
- Go to the Lens Tool Tab and select the Lens Correction tool.
- Select an image or multiple images from the browser.
- Check mark the Diffraction Correction check box to apply the process.

This doesn't clarify if the Diffraction Correction depends on the aperture value in the image EXIF metadata, or if the degree of sharpening is dependent on the image itself. In the case of the former, I wonder where that puts images without lens metadata.
