Aperture export strategy?
I have been using Aperture for about a year and am very pleased. I have imported about 30,000 photos that are organized into projects by dates. Each photo has been renamed by date and place (2011-12-31 Canada, On, Toronto); geotagged; and optimized with minor color or cropping edits. The file size is now huge. I do not care about non-destructive accidents. I want only one decent copy of each photo now. How can I export the modified and tagged photos onto a new hard drive for use by other PC programs or family members, and then import all of those photos and projects into a new Aperture library. Will I need to retag everything with geotagging and keywords again?
Thank you.
