Another stunner!! Did you try the selective tool, reduce the size of a few of them along the top, reduce brightness. It might work. You got to have a few but if you make them slightly larger than needed then edit them with a brush afterwards it might do the trick.
edit- I did an even easier way with your image, sorry I pulled it to see what could be done in snapseed.
lower curves to darken photo, then edit and select inverse, and paint the light back in. It’s what I’ve been doing a lot of.
What a great image! I use a 50% grey layer on overlay and black and white brushes to lighten or darken areas. Yes, it’s a holdover from Photoshop days.
Thanks, folks. I feel like this is an effect that I might keep on pursuing.Love the greenish look! It says dilapidation in an unusual way
