Hi,
In Lightroom I use five keywords for aviation photos: Serial, Type, Unit, Country, Airbase
The keywords are structured as follows:
- Under Types, all types used as a keyword are listed
- Under Airbases all airbases are listed as ICAO - Airbase name
- Under Air Forces, several subfolders exist per country. Per country, two subfolders exist with Units and Serials
- Under Events, I list exercise names etc which I occasionally use for aviation photos (but mainly for other photos)
- Under Personen, persons are listed (so not in use for aviation photos)
Adding keywords is quite simple and can be done in several ways. I do like the Keyword presets and adding keywords by clicking the buttons, or by drag&drop. For instance, this picture has received the keyword "Pasen" (obviously...

)by clicking on the keyword button "Pasen" which appears after using the keyword for recent pictures. The keyword itself is eventually listed in the keywords structure under "Events"
