Begin by loading up the color shot you want to convert. Then Open the image in Photoshop and go to image > calculations. A dialogue box will pop up.

Next, you’ll decide on the blending mode you want to use. What to choose really depends on the kind of results you want to get. For instance, you can set one channel red and another green and the blend mode you choose overlay. The result should be an instant black and white document. You can still edit the result further using a new channel.
Remember you can keep changing the channels you’ve selected to see what effect they have. The mostly used blend modes are soft light, multiply, and overlay, since they give excellent results. You can also adjust the opacity, which alters the strength of the effect.
Once you are satisfied with the results, you can click OK and have your new black and white image. If you are keen, you’ll notice the image is set to ‘Alpha.’ If you want to continue editing it, you should convert it to RGB.
