You can't "open in" to get a photo into Lightroom.
You have to save the RAW file onto your hard disk somewhere, and then Import it into Lightroom.
Thanks for your answer. The thing is once I have it on google drive or in iCloud I do not have any option to save to disk.
If if I do it from my camera with a cable it imports the photos straight to my camera roll and I can open them in Lightroom.
The big big question how to force the raw file from my email to my internal storage...
Any idea on that?
Thanks again for for your quick response.
Using your e-mail software, you have to save the RAW file onto your hard disk somewhere, and then Import it into Lightroom.
I have a similar issue. I'm out of town without access to a computer, just an iPad. I have raw files on google drive. Are you all saying that there is no way to get the files in the cloud over to the iPad to edit them in Lightroom on the iPad?
Lightroom will only import from the photo roll on the iPad. So you have to add the raw image to the photo roll somehow. With dropbox for example what you do is select the raw file in the dropbox app. Hit export from the ellipsis (...) menu and select "save image". This saves it on your photo roll on the device. Now you can import it in Lightroom using the "camera roll" option in import and you will see it is a raw file/dng file in the import interface. I am sure it works very similarly with google drive.
P.S. it is annoying that Lightroom mobile will not import from any cloud service, not even the CC cloud drive.
