I'm trying out Lightroom CC (switching from Aperture), and am a little lost about how things are organized. In Aperture, everything was in the same place, and I would import pics to a Project file. Lightroom keeps the pics in a different file system, using Catalogs, Folders where the actual pics are kept (I think), and Collections. I've imported my Aperture pics which show up as Projects in Collections, but the actual photos are stored in a different location within Folders. I usually take morning pics and add them to an Aperture Project named Morning. I thought I had selected the Morning Project/Collection when importing some pics from the SD card, but they didn't appear there and I had to drag them in from the Previous Import Catalog. I've figured out how to install the Nik Plugins which I love to use. Can you guys refer me to a good online tutorial to help me wrap my head around the file system/workflow? I'm hoping using Lightroom CC could save me some space on my SSD, sharing directly to Flickr and Facebook, where in Aperture I had to export pics and then upload them (potentially doubling disk space used).
