I often review my photos trying to understand what focal lengths would suit me best for specific task.
For example, if I shot with 70-200, but ended up cropping significanlty, I would take 100-500mm next time.
Right now I have a Bash script which compares my final pictures with RAW originals and calculates what focal length my final crop equals to.
For exampe, if I shot at 200mm and cropped 6000x4000 RAW to 3000x2000 JPEG, my script will show me 400mm effective focal length.
It would help me a lot, if Lightroom Classic could display focal lenght equivalent of my crop in Loupe view and if I could use it in metadata filter in gallery.
