This is a great tutorial!
Thanks Moodville for the great info!
I'm still playing with this, and I am starting to get
better at picking colors that fit.

True. It isn't difficult to achieve the same effect in other editors (although not as easy as in Photoshop), but it involves using layers with different blending modes so isn't legal for basic editing challenges.

I would call it a great start for a tutorial, since i (and i think a lot of peeps with me) have played around with duotones yet, but not fully understanding what they're doing. My comment would be to shorten the first bit (i know how to get to duotones, and it's very easy so skip the example-pictures here) and expand on the parts where you add more ink to the shadows with some more example-pictures (with more/less ink1/ink2 in the shades/mids/highs) etc.

When i read it i went to play with duotones immediately only to find out those curves are rather tricky! ;)

Like anything, there is a learning curve to accomplishing a successful duo/tri/quad-tone. Moodville has laid the foundation for people to explore this process. Beyond that, it is up to people to learn what looks good for themselves.
just my 2 cents!

The tutorial was mostly for people who dont even know the first thing about how to create a duotone et al and so it was a quick step-by-step guide to the basics. I may write a part II and concentrate on the various inks and curves and their effects, but I'm certainly not an expert and a lot of it is personal preference and practice too.

I'll be happy to discuss this with you ... I'm bad at getting things written but good at outlining and editing, and I have a lot of experience with this (I've shot duotones on a process camera, before Photoshop existed). Maybe we can combine it with the needed tutorial on Curves, since they use much the same principles and methods.

As a general guide, if you are combining Black with a second color, make that a lighter shade than you think you'll need, because it will darken up a lot. If you look at the gradient at the bottom of the Duotone dialog box you'll see how the two colors combine across the tone range.

Most commonly, duotones use the color to carry the highlights, and the black to bring in detail and depth to the midtones and shadows. The Black is often held out until the 15-20% range, and the color is often "topped-out" at about 70% so the shadows don't get too dark.

Duotones (and Curves -- can be used as if you have an RGB Tritone) are wonderful tools for creating digital art or oddly-colored abstracts as well. One of my (surprisingly) higher-scoring photos is a Tritone:
