been two years...
Your submission should only consist of two tones (black/white, sepia, etc).

| Black and white is usually considered a monotone (grayscale) image, not a duotone, as would any single color on white. Otherwise I like working with duotones -- I've done them for actual print jobs ... rememeber that a true duotone is a holdover from printing, where two colors of ink are used. |

| Would duo tones be the same as the split tones? |

I don't think so ...
In Photoshop to make a "true" duotone you first make a Grayscale image (Image > Mode > Grayscale) and then make the mode Duotone.
You then get a dialog box where you can select the number of inks (two in this case), pick the colors, and adjust the tone curve for each ink to control the blending.
To see how it works try loading a few of the Duotone Presets.
You can also tone or tint a photo by using a couple of Adjustment Layers: first the Channel Mixer in onochrome mode to make an (apparently) grayscale image, and then use a Curves layer on any one of the individual color channels to tint the photo.
I usually use the Blue channel, in one direction it will add a yellowish tint which can look somewhat like a sepia-tone, and in the other direction it adds a bluish cast which looks somewhat like a print toned with selenium.

i just copied the challenge description from Duotones II challenge page, but i'd be up for it NOT including B&W. |

| Part of the confusion is that a true duotone is not a photographic process at all, but rather a printing process designed to mimic or simulate the look of a photographic print which has been "toned" (most commonly is probably a sepia-tone) by using variously-sized dots of two colors of ink. The (white) paper background doesn't count as a "color" in this case. |

Do regular black and white images count as duotones or they have to be tinted?

According to the posted challenge description B&W is included as well as tinted images (a duotone can be any two colors, not just black plus) ...
However, it is not possible to guarantee that all voters will read, or even necessarily agree with that definition. |

Ok for examples, I am just playing this will not be my submission..
I tried this in lightroom as a duotone... using the split tone colors and balance
For some reason my photoshop has the duotone is greyed out and it will not work, I am working with the PS 5..
Would this be a kind of duotone

| To use the Duotone mode you first have to convert to Grayscale mode. |

This would be a good example of a "modern" duotone, one that's oriented to digital photography rather than analogue; in print days, we'd have called this a "toned image".

Done with Picasa's duotone application. Okay?

| Take a b&w image to start with. This is a duotone by itself (two tones only, black and white). Then imagine it printed on a colored paper with an ink other than black. In print development in film days, this was done by using chemicals to tint either the exposed part of the image (the blacks) or the unexposed part (the whites, or the paper). The printer could have used both techniques at the same time with different colors for the different parts, as well. |

One would certainly hope so. |
