How to imitate Ricoh's Bleach Bypass effect on Nikon D90?

Ricoh cameras have a cool Bleach Bypass effect which I'm trying to imitate on my Nikon D90. I decreased the saturation, and increased the contrast, however it is still not the same. What specific setting should I use either directly on my camera, or on Nikon View NX2 to get this effect? Should I also change the white balance and the color tone in a specific way?

Thanks for any help

Added (1). Is there any way without Photoshop? Either directly on camera (by playing with colors) or with the free software of Nikon (View NX2)?

It's a snap in photoshop…

Don't even think about doing it in camera.

Imagine if you just happen to take the best photo you ever took - surely you would want to have it in all its glory, right? People so often regret having only a b&w (or other effect) photo, and ask how to turn it back into colour, which of course is impossible to do.

Always set your camera to biggest size, best quality (and to color).

That way, you start with the best possible photo as your original.

Then you make a copy and edit it to your heart's content.
You have much better control over any editing on your computer, even something as simple as b&w will look MUCH better when it was processed properly instead of in camera.
You can do all sorts of things to it PLUS you get to keep your original.

Is there a way without Photoshop? Sure there's…

For a project like that, you need an image "editing" program.
If not Adobe Photoshop, then PS Elements, PaintShopPro, Gimp or even Photoscape (the last two are free).
Using a website is fine if you only want to do a few photos, but resident programs are the much better option if you have more or want to do this regularly. If it MUST be a free website, try http://pixlr.com/ or http://www.sumopaint.com/ or http://aviary.com/.

I just typed "image editing" into the searchbox here on YA, and got 12317 hits.
