Here's the thing: I've created a virtual copy of a photo in Lightroom to work on it. Once I'm done with Lightroom, I send it to Photoshop to make a few more changes with layers and stuff.
My problem is, when I close Photoshop and come back on it later, all of the layers are gone and I'm stuck with all the changes I've made into one, without any way for me to go back on one specific change.
Would you have any idea of how to either show all the layers again, or how to do otherwise for the next time so I can see all the different layers..
Once you open an image from Lightroom into Photoshop, then make some edits and save the file, it goes back as a tiff or PSD to Lightroom. If you open it again, it won't retain all the layers. To get by this behavior you need to save the file as a separate PSD file by going to File > Save As (OR Save a copy).
