A nice side effect of my Black Trees combo is that the Nebular filter alone – without any external filters – produces a look with white trees and a blue sky straight out of the camera, very reminiscent of the classic 720nm style.
By the way, I’ve refined the combo so I can now shoot with shorter shutter speeds – around 1/300 at f/5 and ISO 200 – almost like a normal setup.
Here are some impressions.
First: just Nebular.
Then: Black Trees.
