My thinking is two fold on converting to B&W. First I have the option of either B&W or color, and second I can get better tonal ranges by converting. Here is how I learned to do it: For this example I will be using Photoshop 7 but almost any photo-editing program that supports adjustment layers will work) Open a copy of your image in Photoshop. (Never use your original just in case of a crash or something) Once you have your image open make sure you are in RGB mode. 1. Click on Layer on the Menu bar, Go to New Adjustment Layer and choose Channel Mixer. Click OK and the Channel Mixer dialog box opens. Make no adjustments just click OK 2. Go back to the Layer menu again, go to New Adjustment Layer again and select Hue/Saturation this time and click OK. 3. The Hue/Saturation dialog box will open. Lower Hue to -100 by sliding the center tab all the way to the left. Click OK to close accept the change. 4. Now in the Layers Palette (lower right hand corner of your screen in the default view) double click the Channel Mixer layer to open the Channel Mixer dialog box. 5. Once the dialog box is open change the Output Channel to Red and adjust the colors to adjust the tones in the image. Make sure you have the Preview checked so you can see the changes in the image. 6. Repeat this step for Green and Blue options. 7. Once you have adjusted these colors to your liking click OK to save the changes. 8. Save the file as a PSD and that?s it! Great tonal ranges in B&W!
