i'm looking for advice for better organization of existing work from various sources:
hassleblad (Phocus processed)
scanned files
OMD and leica files (capture1)

1. i have not been adding keywords to metadata but would like to start doing so and go back and do so in past images. Best way to do this? do ti tot he processed files or the raws?

2. once keyworded, is lightroom the best way to find things, make sub-group lists, eg.?
