hey all I just got this really great book for christmas called text text Mastering Digital Photography and Imaging by Peter K. Burian He has the most awesome tecnique for changing all of your color images to black and white without loosing your tonal value!!. Now I don't know about how you do your images but I think that most of us just use the mode of our imagews from RGB to greay scale. Another popular way is to desat your images. What he suggest is that you use you channel mixer in adobe (or other software)
Here is what you do!
1. Open a color image that you would like to convert
2. Choose window----> channel to open the channels paette. Click each of the color channels (red, green, and blue) in turn. Each will show you a greayscale verision of the image, as it appears when using only the channel.
3. Decide which channel makes the image look closest to your expectations for the final result. For the purpose of this exercise, let's say green is your "peferred channel" Click the RGB thumbnail in the channels pallate to return to your full-color image.
4. Create a new adjustment layer for the channel mixer (choose layer->new Adjustment layer-> Layer-> channel mixer.) click OK in New adjustment Layher dialog box,
5. Check the monochrome option in the channel mixer dialog box to convert you color image to black and white.
6. as a starting point, ser the value for the channel that looked the best in step 3 (Green in this example) to 100%. Set the other 2 to 0%
7. Now you can experiment with the fine tuning all three channel value to achive by setting different percentage for each channel. Set the highest precentage for your prefered channel, Ideally the total precentage( all three level values) should equal 100% to retain accurate density in the final image, but that is just a guideline. It all depends on tyoe of subject in the image and you own preferences
I hope this is of help to you all. I would like to see some of you images if you try this technique..I haven't had a chance to try it yet because my trial of CS has run out and my elements 3 is on back order..
I recomend this book HIGHLY!! it is the only basic digital photography book you will ever need |

Anni, I don't have time right now to try it, but I copied the instructions into a word document and filed it away safely for future reference.
Thank you very much for sharing, I'll think of you when I create my first masterpiece that way *s*. |

It's a fine technique, Anni; one I've used to excellent effect on the few occasions when I go monochrome. It gives tremedous control.

Thanks for the links and tips. I was just looking for this info. I want to rework this one. Wasn't too sure of the composition, though. Thought I might reshoot it...

cool i just learned how to quote.. I thinnk that the compo is okay the only thing that I would have done differnt is crop so that the line leading to the barn was a bit more but not entirely in the center.. I think that this would make that line stonger and focus more on the leading line and the barn rather than the surrounding trees....
shees I read one book and I think I am an expert...heheh no I know I am not but that is just my opinion. |

That's funny.
Everyone has an opinion and I appreciate yours! I wish more people (myself included) would voice their opinions. One of my resolutions is to critique more photos! |

The photoshop book for digital photog's gives that example as well. It's fun to play with to see the different results you can get going to b&w.

I have had good results using channel mixer ( monochrome) and a color balance layer underneath to tweak colors along with using different % of each in channel mixer. This seems to give me better and more controlled contrast. an example is this one
