Sometimes, the correct rendering for an image is the result of complex adjustments being applied on an original image (the master). Peakto therefore relies completely on the catalog native app (Photos, CaptureOne, Lightroom,...) to provide a preview because Peakto is unable to reconstruct such complex renderings.

Such previews usually exist, but are not guaranteed to be of a very high quality. It depends on many factors.

The image inspector in Peakto has a dedicated section for Previews where the caracteristics of the available previews are detailed.
