I am happy with Aperture, very happy actually, but I want to move due to the larger user base of LR, the books, classes, resources available, the presets, etc. I am really a beginning serious hobbyist, so before I get much more invested in learning Aperture, I want to formulate a plan to move to Lightroom. My Aperture library is a Managed library of about 16,000 images. I don't care about losing metadata or adjustments, I lost all of those when I imported them from iPhoto 6. My images as managed by aperture are in Folders by year, with a project for each month included in that year. I would like to have a similar set up in LR. So, can someone tell me what I need to do to move this all over? I think I need to relocate masters, but how do I need to set up LR before that to get ready to do the import? I would like to keep images arranged in folders by year, subfolders by month, maybe even subolders by date the image was taken. Also, Which books/ classes would you recommend for a person in my situation? I really don't like Lightroom at all. I have gone through two trial versions of the software. So much about it doesn't make sense to me. I know that I have to be missing something, because everyone else loves it. Thanks for anything you can tell me/ resources you can direct me to during the transition.
