Are you talking about Aperture albums, or projects? A photo in Aperture can live in multiple albums, but only one project. And are you talking about the representation of these *projects* or *albums* in Lightroom?
Lightroom has a folder organization which mirrors the organization on the hard drive. This file-system organization came over from your "referenced" Aperture photo structure, or it is flat, if your photos were "managed". Or a combination of the two.
In either case, you're probably talking about Lightroom "collections". When importing, you must first chose a location on the file system within Lightroom and then create collections. Your newly-imported photos can coexist in collections with your new Aperture collections. And, you can import into the same file system location within Lightroom. But You cannot simply first import to a Lightroom collection.
Might be worth some time reading up on photo organization. It's quite different from Aperture.
Thank you. I do know the difference between albums and projects in Aperture. I was trying to import a photo to an Aperture project in Lightroom Collections. Yes, Lightroom data management is very different than Aperture. I have been trying to do a lot of reading on it, but at this point it is overwhelming. But I do now understand what you are saying that imports go to a Lightroom folder and then can be put into special collection.
How precisely are you trying to import add a photo to an Aperture project in Collections?
After importing the photo into LR, you'll see it has arrived in a folder. So with the photo visible on screen, drag the photo itself (grabbing the photo and not the frame around it) and simply drop it in the project/collection.
I was trying to import a new image from camera memory card to light room and then put it into a project in aperture through lightroom. It would be easy just to add it directly to Aperture, but I am trying to shift over to Lightroom so I have been trying to see how things would work. Thanks for explaining how to do that. I am working through Victoria Bampton’s Lightroom 5, but the data management system is so very different. I really need to shift to thinking of keywords instead of albums and projects, which I have been using for many years.
