Yellow/blue highlights/shadows revisited

[Pics2]

So, that's the effect (and term) that's been around for a while (like the other things I learn here - D/B, inverted high pass etc). But, I still can't figure out how to do it.
Can somebody please explain again how to achieve yellowish highlights and bluish shadows in pure Photoshop that we see in most of the fashion shots these days.
Thanks!

Activate the Blue Channel in Curves, then raise the bottom end slightly and lower the top end. That's the simplest way to get the hang of the basic effect.

Thanks! I knew it was simple .
Talking about terms used in retouching language (and without starting a new thread), the one that pops up very often is color mapping. And since I thought that it has to do something with the previous effect, I wanted to ask what it refers to?

I use a color balance adjustment layer. Select highlights, adjust yellow blue slider to the yellow sid. Select shadows, move yellow blue slider to the blue side. Make sure preserve luminosity is checked. I keep the midtones neutral.

I also create a wicked sepia tone with this tool. First, convert to B&W using your preferred method. Then add color balance adjustment layer. Midtones: Move +30 red, midtones 0, -15 yellow. Shadows: +20 red, +12 green, -12 yellow.

There's also a very nifty plug called Photokit Color 2 from Bruce Fraser at Pixelgenius. It not only gives you a variety of split tone presets but there's an action that allows you to see them all together on screen.

What about Gradient Map in Photoshop. Can it be achieved with gradients and how?

Re: Yellow/blue highlights/shadows revisited

OK, I've figured it out.
Gradient map, 0,0,255 for shadows and 255,255,0 for highlights. The same look that Curves blue channel adjustment produces.

In photoshop there are always many ways to skin a cat. I've been using it since the mid-'90s and I'm still learning new ways of doing things here and elsewhere.
