I'm having trouble doing this as it is always exported as a Tiff. Is there a way to do this without exporting to say the desktop and then importing from there?
The raw file provides the original capture, you can't attach adjustments to a raw file. So, C1 can open the raw file from the same folder LR2 uses. The tiff has all the file data including adjustments, a good file format.
The benefits of C1 is its handling of raw files--which is much better than LR2. I'm not sure why you would want to first import the file into LR2 and then go to C1? Seems to be backward. My work flow goes C1>tiff>LR2>fine tune w/Nik or CS4.
