I download from a Canon 5D to Lightroom on iMac and two copies of each photo download. I download the same photos to Lightroom on Macbook and one of each downloads. How can I stop this?
The camera can record in both formats, and the two versions of Lightroom are different. I think the problem lies with the camera setup and I need to study the manual in more detail.
Thanks for the reply.
But are you seeing a separate JPG and a RAW file for each photo in Lightroom? i.e. two identical photos.
With the setting in the screenshot above you can set Lightroom to show the JPG and Raw versions as one photo or two identical photos in the Library (sounds like that's your setting on the iMac).
