Seeing Red in RAW

Just yesterday I published a post where this climbing bag was the finished result:

ISO 800 50mm 0ev f/3.2 1/60

While I was working yesterday, I saw in my textbook that there was a way to desaturate an image selectively using Camera Raw.  It was a technique I had never tried before, so I thought I would give it a shot.

Here is my finished result:

ISO 800 50mm 0ev f/3.2 1/60

I found this pretty interesting, and there would be a lot of fun ways to edit using this technique.  It was very straightforward as well.  I opened the image in Camera Raw from Bridge.  From the original dialogue box I clicked open the HSL/Grayscale tab and made my adjustments.  Here is a screenshot of the settings that I used:

Here are the settings I used

I started with desaturating all the colors but red and then decided to boost the reds just for fun.

So what do you think of my red version?  What kind of photo do you think might work with this technique?  I am thinking a landscape or floral photo.

Cheers!
