In PS3 if I just want Black, White and Brown, how do I go about doing that?

In this photo, I changed it to b&w but I want to keep the browns in the picture. How do I go about doing that?

Thanks!

use the duotone filter, which will give you other options, including tritones or quadtones.

then use black and whatever grey and brown shades you wish.

Another option is to use Hue/Saturation to desaturate everything except the browns. You may then have to play with level/curves or Brightness/Contrast to get good contrast.

I tried the duotoner and couldn't get the results I was looking for. I have been playing with the saturation (taking away all the greens and such) and that has been working a little better.

well you could isolate the brown on a new channel/mask/layer and then desaturate the rest...and blend a little..

How would I just isolate the brown? There are a lot of branches/trunks and such to select individually. Thanks!
