If you need to adjust the capture dates, Lightroom has tools to do this and an option to reset the date in the original raw files' EXIF data.
- first make a backup of everything - import it all into Lightroom - one group of files at a time, put them into collections and get them into the right order - be sure that in LR's Catalog Settings, Metadata tab, the "Write date or time changes into proprietary files" option is checked. - use the "Metadata->Edit Capture Time..." command to change the file date and time values, one group at time - once all the files sort properly by Capture time, use the "Library->Rename Photos ..." command to name them in sequence properly. - back them up again. It's always a complex process to sort out a mess. :-) On Tue, Mar 1, 2011 at 4:31 PM, John Sessoms <jsessoms...@nc.rr.com> wrote: > I'm trying to get my all of my digital photos organized now that I have > sufficient storage space to keep them all on one drive.
