I was trying to do this myself, using various things in Lightroom, but I have never achieved result that was worth it. I was trying to get reflection look like on this photographs from James Moes maybe from photo like this one:
Photo from this Album
Here you can see that. It's like gradient coming from left fading towards right side of photo. The warmth on the blackness.
Have anyone advice how to achieve such this effect. I'd be very thankful.
