The preview window tends to show the effect of the corrections as well as possible. 
Keep in mind, you can only appreciate their effect by viewing the exported image.
* It has been resized (depending on the intended use) or full size.
* The sharpness is also dependent on the compression.

Display overview

Full-screen mode is ideal for sorting at the beginning of a session and then viewing the work you’ve done (F11 /Shift+ Cmd+ F).

The “Corrections Preview” can be hidden by the toggle:
Menu: View – Image information overlay (Ctrl+ H / I)

Some effects of image definition corrections are only visible in preview with a zoom at least of 75%.
The preview mode displays all corrections only from this zoom value.

To achieve a faster display at zoom factors below 75%, the HQ noise reduction (the permanent display mode), dead pixels and moiré corrections are not activated.
Also DxO estimated that below this value the improvements of the sharpness of the optics as well as the correction of chromatic aberrations are not compatible with the imprecision of an interpolated view.

Always try to view your image at the closest ratio to 1:1 to best judge the corrections made. An Ultra High Definition (4K) screen makes a difference. – All rights reserved – tous droits réservés.
