Workflow to Grayscale

Camera Raw 14.0.1.952

Clicking on the gear icon to access the Workflow options where I want to use and create a preset that applies true neutral black & white vs the default Monochrome option which is still an RGB image with irregular RGB values. When I select Color Space, the dropdown menu of profile choices doesn't list Grayscale or Gamma 2.2 which will cut out all color. Is there a way to add a profile or a better way to get a Grayscale?

I understand.

I just would've thought that by selecting B&W it would automatically zero any settings that would introduce col on top of B&W.

Thanks for your help sorting this out.

The conversion to B&W is 'higher" up in the edit 'stack' if you will. But that is simply one kind of edit and others might be desired, again as I outlined, to do a Sepia Tone (or split tone). In the end, it is all compounded if the edits are applied. When you disabled that one pane, or had you reset it to 'zero', then it wouldn't have caused the color cast. Each pane zero's out on it's own so to speak.

This is all about converted files. But how to open a natively monochrome file from a Monochrom camera in Greyscale?

Monochrome raw files behave the same way as color raw files.

You can only render them into RGB (or CMYK) files, grayscale is not an option.

If you really want a grayscale file in Photoshop, use Adobe RGB, then convert to Gray Gamma 2.2 in Photoshop.

Note that support for grayscale profiles outside of Photoshop in pretty much non-existent.

Any image that leaves your computer should be in RGB, or CMYK if that's a requirement.

ACR will only render into an RGB color space. If you want a single grayscale channel file you will have to do this in Photoshop.

When I originally searched the question, this page came up, the author suggested it to be the route to achieve Grayscale neutrality in ACR.

I couldn't find the option as per my original post .

Could you convert to grayscale neutrality (exactly the same RGB values) in earlier vesions?

Is there a different way to do it now, before going to Ps?

If you use a B&W conversion, that is, remove all color where R=G=B, while an RGB document, it IS neutral. But it has three channels. A grayscale document has one. And you can, as outlined, do this in Photoshop if you really, really, REALLY need a single channel grayscale document. Again, ACR engine is RGB. So you can produce a neutral conversion in any number of ways within it. Then render into an RGB Working Space like sRGB, Adobe RGB (1998) etc.
