CR2 files are Canon RAW files from a Canon digital camera. How did they get on the iPad? How are you downloading them from the iPad to your computer?
OK. So if they are on the computer are you saying you imported them into LR but they don't appear in LR? What about trying to open them with DPP to see if they are still OK or got messsed up during transfer.
Is this the process you used?
After you have transferred photos to your iPad using the CCK, you may be wondering how you get them back off the iPad.
You do this by connecting the iPad to a computer using the standard sync and charge cable that came with your iPad. When connected this way, the iPad appears as a removable drive in your file browser, just as if you had connected a camera or a card reader.
You can then copy the files over to your computer using the default file manager, or using the import function within your desktop software such as Lightroom or Bridge. The raw files will be just the same as if you can transferred them from your camera or storage card."
I don't know what CCK is but i downloaded from camera to ipad using the relevant connection from camera to ipad. When i got back to Australia i downloaded lightroom and followed the lightroom instruction yesterday to import into lightroom. The computer sees the ipad and downloaded Shots taken with Sony camera. I notice that it has also imported some old CR2 files that were on the ipad but it has not imported and will not import recent CR2 files or the attached jpegs.
On preparing to download again i notice that the Cr2 images that were successfully downloaded from ipad appear as thumbnails but the ones that did not download appear just as a CR2 logo. No image appears for those
