Digital Image Manipulation – Colour to Black & White in Photoshop CS6

I am doing a post of all the different ways to change a colour image into black and white because there are so many, and it is important to know which one to use for which image, and why. I am using Photoshop CS6 but I think that all the ways I mention are the same on all the creative suites. Using a simple image I will put a example of the different results at the end of the post for comparison. The results may not appear that different from each other because when viewed on the web the image resolution is 72dpi, but as a photographer I work at 300dpi when editing photographs, so working in much more detail than what can be seen on a computer screen, so what you see on here is not as accurate as my images at 300dpi when printed.

1)Image> adjustments> Desaturate

2)Image> Mode> Grayscale

3)Image > adjustments> Channel Mixer> Monochrome OR to do the same in a new layer Layer> New adjustment layer> Channel Mixer> Monochrome.

4) Image> Adjustments> Hue/Saturation> take the saturation all the way to the left. This can be done in a new layer in Layer>New Adjustment Layer> Hue/Saturation….take down the saturation.

5)Image> Adjustments> B&W or to do this in a new layer: Layer> New Adjustment Layer> B&W
