Why don't raw files show up in Photos?
I cannot understand what's happening to my raw files in Photos.
I imported some photos from a folder on my iMac's hard disk. When I did the import, "Copy items to the Photo Library" was checked in the Preferences. And it seems to have worked. In Photos, where the files for today's import are displayed, I see a file named "_1010402.JPG". If I use Spotlight to search for "_1010402" (that is, eliminating the filetype suffix) I find both _1010402.JPG and _1010402.ORF (Olympus Raw File format). And they're both in the same folder inside the Photos Library hierarchy. But I couldn't see the raw file in Photos. All I see is the JPEG.
I can see some of my other ORF raw files in Photos.
I asked Spotlight to display those files in their enclosing folder. I selected the raw file, right-clicked and pulled over to Share > Add to Photos... Then the raw file became visible in Photos. But only then.
I read about the option of clicking on the JPEG and going to Image > Use Raw as Original, but I have never actually seen that command active. It's always grayed out. Does not matter what file I select.
Please explain. If Photos isn't going to let me edit my raw files, that's going to be a serious problem (and one I wish I'd learned about before importing thousands of photos).
Thanks in advance.
