This photo was taken in the lavender fields of Brihuega in Spain during a summer night.
The foreground was captured during the astronomical twilight with the following settings: 17mm, 1 min, f/2.8, ISO 1600.
The sky was captured a few minutes later at night, from the same location, with a star tracker: 17mm, 2 min, f/2.8, ISO 800.
I did basic edits with Capture One to match exposures and color, then I did the merging and the rest of the edit in Photoshop.
This is one of my personal favorite images I've taken.
well done. 4-star from me.
