GutairDTO, I'm a fan of everything you make. Period. I wish I know how to use spit tones like that, but my stuff just looks stupid when I try!
Appreciate the kind words! It takes a bit of practice but getting the split tone and/or cinematic look isn't as difficult as it first seems. Most of my shots are PP'd fairly similar. I use Aperture, but I believe Lightroom can do this stuff exactly the same. I always start with curves adjustment, and almost always have an S curve for both the red and green channel. The Red is typically a generous S, whereas I am more careful with the green depending on shot. For the above shot, I barely dropped green in the shadows, but raised it a decent amount in the highlights. I almost always raise the blue channel in shadows and lower in highlights, typically just a straight line.
Then after the Curves adjustments are in place, I adjust contrast, then use the "Tint" color wheel to take the photo from the "Cross process" look to slightly split toned. For the above shot, I actually placed the shadows wheel in the "green-yellow" color area, then put the mid and highlights in the yellow as well. THat combination along with the curves adjustment gave the picture a "Blue-green/Yellow" split tone look.
Hope that helps!
