Duotones have become very popular for illustrations in glossy magazines and in advertising. Duotones color mode in Adobe’s Photoshop uses an imaging process that calculates the highlights and middle in a black and white image, then allows the user to choose any color ink as a second color.
Duotones come from Cyanotype color images in newspapers and comic books and are usually halftone prints and occasionally duotones. Duotone is the generic name for multitone printing, which can be done with two, three or four inks. This process requires that the press be set up with special inks; usually Pan tone designated colors, instead of the standard CMYK inks used for process color printing.
True multi tones use spot color plates, rather than dithered CMYK, but a good emulation can be done using the much cheaper and more available CMYK printing process.
It seems odd to me that with such beautiful color images that we want to convert the image to black and white or duotone. It is essential for a good quality duotone to start off with an image that has a good overall tonal range and contrast. By converting a color image to gray scale, and using the duotone option, by selecting one additional color from the commonly used colors other than black, you will be off to a great economical start.
If you are interested in printing the image, make sure to keep the cost in mind. Cost is depending on quantity of colors used in the image, availability of Ink color, and paper. Enhancing the image with curves can have quite a bit off effect on the finished piece, depending on the image. All these factors determine the best end result you are trying to achieve.
A flat diagonal line will print both colors at the same gray value with an even color range, sometimes this is best, but it will load up in the dense areas, and flatten the highlight area’s. Depending on the changes of curve % highlights, you could manipulate the amount of ink coverage in the deep shadows of the image, you would set a lower percentage of ink in the box labeled “100%”, so, if you are printing black and one additional color you may want to reduce the amount of color in the deep shadows because it does little good there. In the same respect you may want less black in the highlight areas since the combination of black and color increases ink density anyway. So you would possibly set a lower percentage in the 5 and 10 Boxes.

I used the Bridge to select my pictures and saved them as PSD files.
I used the history brush, for cleaning up the brown spots on the green leaves.
Select watter drop with oval Ellipical Marquee tool, and dragged it on the green leaves.
For the watter parts:
The layars Icon menue, Drop down to select layer style - Inner Shadow
- Inner Glow
- Screen (in blend mode)
- watter layer blend to 255
