    I've read a lot about of color to black and white conversion techniques,
    filters, and plugins.

    I'd like to hear what methods/plugins people who do this a lot use.

    (Please do not answer this just because you know how. I'd like to hear from
    the people who do this frequently, especially from photographers that shoot
    people.)

    Thank you very much,

    Drew Faber

    I do a lot of color to B&W conversion, mostly intended for professional
    print on a press.

    Usually, the images I work with are CMYK, not RGB. A CMYK image
    converted directly to B&W via Mode->Grayscale tends to come out a bit
    muddy and dark.

    The technique I prefer, particularly with images that are dark to begin
    with, is to convert the image to Lab color via Mode->Lab, then discard
    the a and b channels in the Channels palette (leaving only the
    luminosity channel) and convert the resulting multichannel image to
    grayscale. This produces an image that is quite crisp and not muddy. The
    same technique works just as well for images that start as RGB.

  3. Have a peek at some of my stuff. I shoot with a Canon EOS 300 and convert
    most of my shots in PS CS 2. Typically play with the contrast while it's
    still in colour and then convert using the channel mixer. Dodging and
    burning and levels and curves to get the desired tones.

    I give all my brides every picture in color and B&W. I use this method:

    http://www.russellbrown.com/tips_tech.html

    Go to the bottom of the page for "Seeing in Black and White". I have it
    in an action followed by an action that converts it to a Duotone. Well,
    I have a Tritone that works well for wedding pictures.

    Most of the time I just set the action at Hue -100 and let it fly. Every
    now and then I need to adjust a picture to something else.

    I also use the Russell Brown technique
    for a pro shooting on Canon 10 D sRGB or Adobe RGB originals, starting from
    JPEG not RAW, to be used in reproducing 8x10 actor headshots, with wonderful
    results.

    Before using that technique I used my own technique as I had no formal
    training in PS and just found my own way
    adjustment layer hue/sat pull slider in center to desaturate, make another
    layer above adjust with curves or levels

    the RB technique is far better and very simple, much more control over the
    individual color values in the image.
