I plug in my camera.
turn it on.
I open Lightroom.
Go to library.
At this time a box that says canon 5D usually opens up so I can select my source.
NOW. I can not find anything that connects LR to my camera.
I am trying to upload pictures.
I have Lightroom 3
It is possible that your operating system is not able to detect your camera or Lightroom is not getting proper permission to access the memory card.
Please copy the images to the computer and try to import them from your internal hard drive.
Let me know if this works.
I downloaded the latest version of LR as a trial run and this new software has no problem finding my camera.
LR 3 can not find it.
If I upload the images into my computer through iPhone, the images are too small. iPhoto will not let me upload raw files.
Please follow the below link to reset preferences to avoid any issues due to the settings.
> Quit Lightroom.
> Navigate to the preferences file:
Mac OS: /Users/[user name]/Library/Preferences/com.adobe.Lightroom3.plist
> Rename com.adobe.Lightroom3.plist to old.com.adobe.Lightroom3.plist
> Relaunch Lightroom
Hope this helps.
