Unfortunately I have not mastered colours with the D70. This curves thing is a whole lot more complicated then it sounds.
I did adjustments in Photoshop before posting. I like the National Geographic type of deep saturation. Faithful colours is never my aim.
For #2, I adjusted the saturation for the red channel, this way the gray at the top and bottom still looks neutral.
Apparently. For contrast and saturation of the pics, the lense makes a big difference. I was shooting with both the cheapo kit lense and a Sigma 70-300. I just got myself a 60mm f2.8 micro, this lense is suppose to give you very saturated and contrasty images. I'll try it out this thursday. Until I can afford 3 thousand dollar lenses, I'll need to reply on photoshop.
