OK, here is some of my photo software history. I am currently moving from Windows to Linux as my primary PC operating system, about 90% complete. So, some of my software selections are changing.
1st - file manager and whatever came with Windows, as in Window 3.1:-)
Irfanview, works in Linux under Wine
Picasa, Windows only, as far as I know.
XnView, organize, crop, rotate, Metadata, still in use, works on Linux and Windows
Photo Mechanic, import and organize, no longer used, Windows only.
Rapid Photo Downloader, import and organize, Linux
DupeGuru, find duplicates, Windows and Linux
FreeFileSync, sync and backup, Windows and Linux
TonFotos, organize, facial recognition, search, albums etc, Windows and Linux
various photo editors
Tonfotos is my current goto for organization but it is not yet stable under Linux :-(
Cheers,
Gord
