Hi, since I have updated to PS 2017 Lightroom no longer asks me if I want to edit a copy with LR adjustments, a copy or the original in PS. How do I fix this? Thanks!
If you are talking about raw images then that message isn't necessary. When you choose to edit the raw file in Photoshop, Camera Raw converts the image as it transfers to Photoshop. Then the new copy is created at the end of your Photoshop work. When you close the image in Photoshop you will be given the choice to save or not save it. If you are talking about non-raw images and you are not getting that message then you probably need to reset your preferences.
The other reason you are not getting that message is because Lightroom and Photoshop/Camera Raw are up to date and in sync. It isn't necessary for Lightroom to create a copy in order to send an image to Photoshop containing all the adjustments.
