Q: photos shows exclamation mark when opening thumbnail

Hi,

When I open Photos I see all my photos as thumbnails but when I click on them to open a grey exclamation mark appears. The database is approx. 25 gb large so the photos should be in there in high resolution. I imported most of them directly from my camera into the program. I have already tried the repair option using the option and command key. I have version 1.5. Does anybody know what the problem could be?

Thanks!

iMac, OS X El Capitan (10.11.6)

What has changed since it worked? Have you done any cleanup of your computer deleting files using the finder or cleanup software - that is the most common cause when it is not database corruption?

Are you shooting RAW?
If yes, is your camera on the list of supported cameras, see: Digital camera RAW formats supported by OS X El Capitan - Apple Support https://support.apple.com/en-us/HT205272. ?

If the RAW format of a camera is not supported, the thumbnails will look fine because of the embedded JPEG previews, but the full image cannot be displayed.
