Hi,

I have two iPads - both on 8.0.2. I used Airdrop to transfer 3 pictures from one to the other. When I went to view them later on the target iPad - they were there but the resolution was really low. The originals are Nikon Raw files (NEF) so I suspect only the thumbnail preview was transferred. I know IOS 8 just now is very laggy in the photos app for viewing images, especially these RAW files and I assume this is another bug.
Has anyone experienced something similar using Airdrop? Has anyone tried using Airdrop to transfer the original image files, especially imported RAW files?

I've not noticed that, but I've noticed when sending photos to iPhoto on mac via airdrop, location metadata is stripped. I wouldn't expect that to happen if it was transferring the original file?

Hmm, that isn't ideal. iPhoto uses location info so no idea why it would be stripped out.

Okay, found out the issue.

There is a bug with Airdrop and RAW files on iOS 8. Files transferred between devices have a very low resolution. I think it is only transferring the thumbnail previews and not the original files. JPG & PNG files do not appear to be affected. iOS seems to be detecting the NEF file as TIFF and interpretes them wrong. It can’t extract the full resolution JPEG in the file, but only the preview. However, all the RAW file data is still transferred. If you transfer the photo to a Mac, you get a file named "IMG_XXX.TIFF". If you rename this to "*.NEF" you get back the original file data.

I have submitted a bug report to Apple.

Have you considered using iCloud to have the photos show on both iPads

I only needed to transfer 3 images in an ad hoc manner. I could use the cloud to achieve this but Airdrop would have been the perfect solution in this scenario!
