Sometimes it is useful to see the image in monochrome (‘black and white’), perhaps to select areas for action or maybe just to be more informed about what is where.

You can download the macros (free!) and see lots more detail about how they are used in the download page by clicking here: http://changingminds.org/disciplines/photography/affinity_photo/resources/daves_mono_maps.htm
