Need serious help with vibrant colors...

[Lionheart]

Thanks guys first of all!! I've tried filters, demo plug-ins and books. Nothing is getting me colors like that without throwing the picture off. Again, any more suggestions let me know.

Seb, you just need to play a bit in PS. There's a gazillion ways to get to the same end product. A lot of guys like to use layers, which helps give you a lot of control, I just use the basic tools. The pics you posted look awfully contrasty to me, which can make the colors seem vibrant when they really aren't. Here's some examples of different ways to do things.
The first is original, and the next using just levels, and the third just contrast. In both cases the image sharpens and the color seemingly gets more saturated.

now a couple more. The first is again the original, and the next uses the selective color adjustment increasing saturation across the board in the neutrals, and increasing black levels in the blacks. The last uses velvia vision at +31, with +3 contrast and +1 warm.

If you haven't tried it yet, Alien Skin just released a new plugin called "Exposure" that could possibly do what you're looking for. I'll try playing around with PS some tonight too and see if I can figure out some of it as well. I think Lionheart's on the right track.
