Making Black and White Images in Photoshop

This tutorial is to help you turn your colour photos into professional black and white using Photoshop:
1) Go to Image menu
2) Choose Mode > Lab Color (it probably asks you if you want it to be flattened, accept it)
3) Click on the Channel tab, (on the right hand side of the Layers)
4) Drag channel ‘b’ into the garbage can shown on the bottom (or delete it)
5) Drag channel ‘Alpha 2’ into the garbage can
6) Go back to Image menu
7) Choose Mode > Greyscale
Your image is probably very light with low contrast now, to fix that:
8) Make a duplicate layer of the layer that you have
9) Right click on the duplicate layer
10) Choose Blending Options
11) In the default Blending Options, usually the blend mode is Normal, change that to Multiply
12) Play with Multiply Blending mode opacity until you get a good BW.
