1 Graduated Dehaze Filter At The Top
The image can be adjusted with a simple graduated Dehaze filter across the top. Here I used a Dehaze setting of 33. I avoided the bulk of the chimney as I didn’t want it to get strangely darker at the top.
The Dehaze filter darkens the darkest areas even more. Increasing the level of Dehaze, Lightroom darkens adjacent pixels to the first ones. The highest setting dramatically spreads the darkness – some people use this effect on the whole image giving a very distinctive and oppressive look. But for me I think this looks too obvious, so don’t get too carried away Dehazing!
