If some of the Lightroom folks could chime in on providing some advise on what I'm looking to do, I'd really appreciate it. First off, I used to create in Aperture multiple Libraries, mostly by year, so right now I have a 2014 library on my laptop and the 2013 is sitting on my DAS. This helps manage my drive space the best. With that said, I'm looking for something similar with LR. First question can/should I use one catalog or multiple ones, i.e., one per year? Secondly I read somewhere doing some research that I can keep all of my images on a DAS and just maintain the catalog on my local drive - all I have to do is use smart previews - I'm not sure what this buys me. I'm thinking of going to multiple catalogs, one for each year and store the current year on my laptop. Once I move the images from my local drive to the DAS, how will I ensure the catalog will be able to find them, i.e., not looking for it on my local drive?
