Anytime you use the Save As command that file is not auto added to the LR catalog. You have to use just Save for it to make the round trip back to LR.
Could be the Preview file is not being updated fast enough for the edits you have done in PS to show up right away.
Thanks for your prompt reply,
You may be right about the file not being updated fast enough. I just tried it with a smaller file and it reflected in Lightroom immediately.
I could have sworn that 'Save As' was auto added. I've never had this issue before.
How can Save As be auto added to the catalog. LR is looking for a file of the same name to be placed in the same folder as the original but with a different extension. Not with a new name and in a different folder.
I need to revive this thread, please.
I just took some images, which were then Auto Imported into Lightroom. I selected a bunch I wanted to work with and I Opened as Layers from Lightroom into Photoshop. I Layer Masked the images to composite them together and I just clicked 'Save'.
I have done this many times before and normally, when I do this, a copy of the Photoshop edit automatically Loads back into Lightroom, but this time it did not and I had to Synchronise Folder to get the Saved image into Lightroom.
There definetely seems to be an issue with Lightroom and Photoshop working/syncing together.
