Monochrome Option in Channel Mixer

Recommended Posts

I am used to converting color images to B&W by making a new adjustment layer for the channel mixer and by selecting monochrome. Then adjust RGB sliders to my liking. I don't see a monochrome option in Affinity Photo. Will we get this feature? Is there a workaround? How do you use the channnel mixer in Affinity Photo for B&W conversions?

 

I suppose Black & White Adjustment lets me do essentially the same thing, but it has not only RGB, but also yellow, magenta and cyan channels. I presume the total number of percentage should always amount to 600%?

I miss this feature too.

The Black & White Adjustment layer does a different conversion than the monochrome channel mixer option in Photoshop (I tested it with a color chart file). All colors are converted to a very similar tone of gray.

Because of this missing option, I am a bit at a loss about how to convert to monochrome in AP. Would be grateful for any suggestion about alternatives.

I have some sympathy for getting a simplified B&W adjustment using only RGB channels.

But this should be totally separate from channels mixer, which is intended for a totally different use case, and no good basis for what is requested here.
