Re-import Photo to Lightroom
I completed basic editing on a photo in Lightroom 6, then continued the editing it Photoshop CC 2018. After that, I saved the file as TIFF file format. Next, I tried to import the TIFF file to Lightroom, however, Lightroom states the photo has been already imported.
How can I import the TIFF photo beside the original one in Lightroom?
