On this video Colin Smith from PhotoshopCAFE shows how to convert a color image to black and white in Adobe Photoshop.
Photoshop allows for many ways to convert your image from full color to black and white but not all of them will give you the same results and actually as Smith states in this video – some will remove quite a bit of information from your image when doing the conversion, so if you want the full information converted you need to follow the steps of this tutorial.
Here are 3 ways that will let you convert your image to B&W but have some (bigger or smaller) disadvantages:
- Image>mode>greyscale (you will be loosing lots of info from your image).
- Image>adjustment>desaturate (no control of lighter/darker areas).
- Add black and white adjustment layer (pushing the sliders too far can introduce artefacts).
So non of these seems optimal – Smith’s method is different – he uses an adjustment layer and chooses a channel mixer. Be clicking on monochrome you have control of each channel of color. You need to be careful not to pass 100 to clip the colors.
