In the interest of speed and lack of storage capacity on my Windows tablet, it would be great if only rated photos could be
imported to Lightroom. I often do a crude edit in camera while shooting (news, sports etc) and this could speed things up
for breaking news and deadline sports. - John
If this is a suggestion you can add it at the below link and it will get more attention. I suggest providing more details on what you're doing in-camera and what you expect to see in the Import module:
For now you can use Windows Explorer to select only the rated image files, move them from the memory card to a folder on your HD, and then import that folder into LR.
