If I edit and image in Photoshop, direct from Lightroon (Right click edit in etc) when I save the image the edited image appears in Lightroom as intended. However, all the develop settings sliders are now zero. The adjustments previously made in Lightroom are still applied to the image, just the sliders are now zero.
Is this as intended? I can always do te develop adjustments after the edits I need to do in lightroom but any original import settings will no longer be visible in terms of what and value (although still applied).
Is there any way to avoid this? Opening as a smart object has the saem result.
What you describe is intended behaviour. The image saved from Photoshop is a fully rendered image where the Lr edits have already been baked in. Same will apply to a Smart Object.
The image coming FROM Photoshop is a new image that has been adjusted in Photoshop, but has no Lightroom adjustments applied to it. Therefore, all of the Lightroom sliders are where they should be.
