I have taken and edited the above shot in Lightroom to give an evening effect. I would like to remove the green reflection of trees on the lake to darker blue or the color of water on the right side of the lake. But I get only black color(Shadows/Reflection) and cannot change the color in that region. I am a beginner and this is my 5th shot, and I am stuck in editing. I tried even reducing exposure/shadows but its still the same. Please let me know how I can proceed.
