Twilight looks very different in full spectrum, something like night vision in a way. I could barely stumble through camp but my camera with long exposure could see just about everything.
Using a Lifepixel modified Lumix GH3 DSLR with full spectrum capabilities.
The moving water during long exposuress gives motion to it.
A few shots into the forest facing away from sunrise, very dark back there.
With the sun coming up I wrapped up full spectrum shots, moved onto infrared shots throughout the day.
