Funny that you should mention the blue hue, drg. There's quite a bit of it in the photo I'm using as an example here.

I don't much alter hues. I do the normal color cast removal (and ocassionally create a small cast to "lean" a photograph in a particular direction. What I do more than anything is boost them- substantially. I use LAB color for this, as it's different from merely increasing the saturation. The blues become bluer, but at the same time, the blue-magentas are actually driven farther away from the blue-greens. I usually describe it as driving a wedge in between colors. All I know is that the images are incredibly vivid, yet the color looks realistic.

Here's an example of what I'm talking about:http://i42.photobucket.com/albums/e3...IMG_0788-1.jpg

Initially, I didn't like the technique. You look at the image, and it screams oversaturation. Nonetheless, I processed a batch of photos this way and sent them off to be printed (so as not to dry up my ink cartridges...). An amazing thing happened. The lab person told me she rarely saw images that looked that good, and wanted to know what my secret was. A gentleman in the store (who had the demeanor of a professional, but I don't know that, it was just my impression) asked me what camera I used. When I told him I used a Rebel XT, he raised an eyebrow and asked "and you get these results??" I get the same reviews even now at my home when someone sees one on my wall.

I've since come to a conclusion. Color is pleasing to the eye in the same way chocolate is pleasing to the pallette. More is better, so long as you don't go completely overboard. Still, every time I use this technique, I feel like I'm going too far.

I'd be very interested to hear what other photographers think.
