Sorry for bringing this issue to the community. I have always been using Lightroom but I am new to Photoshop. I dont know how to reimport a 4GB Ps created panorama back into lightroom. 'Saving' or just 'closing' Ps doesnt automatically re-import contrary to pretty much any source or tutorial I find on the internet. Please help.
Both Lightroom and Ps are up to date. I knew I could just export it from Ps and then manually import it but thats super inconvenient workflow-wise. However I rebooted the Mac and retried from the beginning and now it worked for some reason. However thanks heaps for you responses. I much appreciate it!
