Description

Taken while camping at Kissimmee Prairie Preserve state park in FL on 03/12/18 around 8 pm. KPP is a class 3 (blue) site, with some of the best skies in Florida, USA.

The difference dark skies make is absolutely incredible. I had more detail in my 90s raws than I could ever get stacking the same exposures from my Bortle 8 home.

Canon 6D, ISO 1600, 40x90s, 30x10s, 30x3s, daytime white balance.

Canon 200mm f2.8 L

Processed raws in Lightroom:
