how to make duotone image having black&white part and color element

[kuifje]

Hi!

With a RGB or CYMK no problem for me to have certain element in the picture distinguishing from the rest. But now I have to do the same building up in duotone (2 PMS colours). It looks like Photoshop doesn't allow to put a black&white layer into a duotone document (it automatically turns into the 2 duotone colours).

So how can i make a duotone image (source = FC) in which a part looks "black and white" (1 colour=black) and a part "lights up" in the second colour (2 colour= yellow)???

Any suggestions or tips in what direction I have to look? Hope to hear from you! Thanks!

by the way:
- so I know how to make a duotone image, that's not the problem
- i know how to work with layers and masks

(i try to upload the image.. but server seems very busy...)

One other way to leave a bit of color in… see if your camera can do it. My Canon A620 has ‘my colors’ mode, which lets you swap or accent colors. I’ve found it to be particularly fun while taking pictures of places like construction sites, where it helps really bring out the machinery. I’ve found it can quickly turn a boring shot into an interesting one.

The trick with the in-camera stuff seems to be finding a scene that isn’t hugely colorful. If you tried to pick out just blue flowers at a botannical gardens for example, you might end up with the flower not blue enough, or the background getting some of the color in it, leaving everything washed with blue.
