Previews Unavailable
I just got back from a photo safari in Africa. I used my Canon 70D and a brand new canon 80D. I used a combination of SD Cards both new and old. I am not sure which card I placed in which camera. I never formatted the new cards - I simply put them in and started shooting. I do not recall ever formatting a card before using it.
I import by putting the card into my iMac and opening the import dialogue box. Before I do this I check in finder and I see where all of the photos I took are present. I can see the photos in the finder. I took everything in Camera RAW and there is a mixture of stills and video on all cards.
On three cards Lightroom shows the number of the photo and a note in the photo box - PREVIEWS ARE NOT AVAILABLE FOR THIS PHOTO. I can see the movies, but not the stills. At this point, I am reluctant to import the photos.
Any idea why there are no previews for these photos? Is there any harm in importing them at this time, even though I basically do not know what I am importing, because there is just a image number. If I do import will I be able to build previews afterwards?
Does this mean the camera failed to build a JPEG preview? This makes no sense as I could see each photo on the LCD screen as I took it.
Thanks for your help.
Steven
