Actually, a blog post about astrophotography mentioned how RAW is a game-changer for night shots. Like, if a comet trail is faint, you can pull up the shadows without making everything noisy. Remember that time-lapse of Neowise? People said RAW let them fix star trails from shaky tripods. Shooting jpeg would have lost all that data in the dark parts. Makes you wonder how many good shots were lost before RAW was common, right?
Heard a podcast where an astrophotographer said RAW basically doubles what you can save from a bad exposure. No way JPEGs would keep those faint comet details without getting crunchy. Crazy how many old photos might have had more data hidden in them.
