Just over 3 years ago (yes, I'm an ancient user of CM  ) Mike had this page on  Black and White conversion through CM . Don't know if it's still there (screen shot 0001). I'm still using it and found that there's more control using the curves in RGB through CM than the sliders in PS. So, here's my B&W effort  http://www.curvemeister.com/forum/index.php/topic,1392.0.html

I like it...very nice...

Hi,

Starting in RGB, I placed a highlight on the snow on one of the branches. I then dragged the bottom of the RGB curve to increase the contrast. After saving it, I reopened the edited image in LAB to increase the saturation.

Ganna,can you post it as a 300kb image?It loses  impact in a smaller size I think.GregM

[ganna]

OK, will try in future

I leaned hard on the contrast  in the brightness chanel in HSB to separate the ice flakes from the sky,then when I went to change the sky in saturation I got a B/W conversion which I was going to try anyways.Hard sharpening for the ice edges.
For the color version I started with the HSB con trast then changed to Lab for the color(file below)In a second pass in Lab I put a neutral on the ice to get a whiter white and better sky.GregM

For me this is a typical B&W image. But I have no idea how to use CM for B&W. This conversion was done in Bibble with Andrea plugin. ok it is a bit special and blacks are blown but...

Hello

I am posting two versions of the branches in the sky image.  I used levels and curves.  I  used both in RGB mode.  It is my understanding that you can perform the same corrections in CM that you do in levels but I am not sure how to use Curves or CM in this manner.  Even my Photoshop Curves adjustment uses auto as a starting point.  I am relatively new to curves and hope this class will answer most of my questions.

Please post any suggestions.

Thank you

Hello,

I decided to try to adjust the tree branches image using CM, however, I believe the sky would look better bluer.  How would I make the sky bluer in CM? 

Thank you

Here's a sugestion.GregM
I  used three dots to anchor the yellow part of the curve.

[Greg Groess]

Greg M is correct and you can go further...

Shot1 is the LAB curves applied to your posted image.  I am also posting a .ACV file.  This file can be loaded by Curvemeister so you can see exactly what was done.  Save the ACV file to your desktop and open your posted image in CM.  Switch to LAB mode in CM and click the "load" button. 

Examine the B channel and notice that I kept the hoar frost neutral by moving the pint closest to the center of the curve until A and B were zero.  Then I bent the curve as shown.

In CM there are a few ways to go Black and white...The fastest is in LAB.  Rotate the curves to be horizontal and adjust the L channel for contrast.

David,
Curves will soon replace the levels command for you.  In levels you have 3 points you can adjust.  The shadow, the highlight and the "mid-tone range" adjusted as a single point.  It would be the same adjustment as a curve with three points.  You would be limited to only 1 mid-tone adjustment point; and as you might have noticed just in this thread the multiple mid-tones adjustments are very important.

Don't worry about being new to curves..that make this all the better... because you will not be fighting your existing knowledge base as we go forward.  Some people have to unlearn some things before they can get into this stuff..

Nicely done by the way...
