Re: [Digital BW] Converting to B&W with Split Channel

Hi Mitchell,
I am very interested in your color to B&W conversion and tried it. I used Split channel option, created three separate files, but I don't know how to copy them as separate layers. Please, elaborate about your procedure in more details. Thank you.

  Subject: [Digital BW] Converting to B&W with Split Channel


  I have not seen any messages that discuss my favorite technique for
  conversion to B&W. It uses a little-known PS feature called Split
  channels.

  Split Channels is a menu option on the flyout menu for the Channels
  Palette. It takes your RGB image and creates a separate grayscale
  image for each channel.

  Almost everyone here will be familiar with using Mode | Grayscale or
  Channel Mixer with the Monochrome box selected to create a B&W image.

  This is even better than using Channel Mixer with Monochrome. Much
  better, IMHO! After you create files for the separate channels, you
  copy them all to the same document as separate layers. That way, you
  get immediate feedback as you experiment with various layers options,
  like opacity.

  I worked on an image last night I brought the blue channel in at 5
  percent opacity in Normal blend. The red channel was 80% opacity in
  Normal blend. The green channel was 95% opacity, but I used Soft
  Light blend for added contrast.

  You can turn the visibility on and off for various layers as you try
  to decided how much of each to incorporate. You can change the layer
  opacity and blend mode. You can even control the set points for what
  gets blended from each channel -- perhaps the shadows from one, the
  midtones and highlights from another.

  I'm working on a PDF tutorial right now.

  It's now the only way I convert from color to B&W. Give it a try!
  Pretty neat stuff!

  Perhaps the Split Channel technique will come in handy for you in
  the future.

  Cheers,

  Mitch
