What options should I be able to see in the Lightroom Export dialog under Color Profile>Other?

When I look at the "Other" Color Profile options in the Lightroom Export dialog, I see only a very small subset of my color profiles, and those are specific to printers. Is this normal?

I want to Export a 16-bit TIFF from Lightroom Classic with a gray-scale profile. I can find some Gray color profiles on my system, but none of them show up in the Lightroom Export dialog.

Ah yeah that is true if you do not compress the tif files. Enabling zip (which is lossless) compression in Lightroom export should give you close to the same file size in an 16-bit RGB file as a 16-bit greyscale tiff. Also greyscale jpegs should be the same size or close to it as the rgb files. I just tried this and a 16-bit RGB tif file from a black and white image is 86 MB while if I convert that to a single channel greyscale image in Photoshop and save as a 16-bit single channel tif with zip compression using the Dot gain 20% profile, I get a 73MB image. Hardly a factor of 3. I have not come across any software in the recent decade that doesn't understand zip compressed tif.

On my system in 'other' I see all profiles that are available in /Users/<myusername>/Library/ColorSync/Profiles/ that are not display profiles and that are not cymk or greyscale profiles.

Regardless of the ICC profile, it needs to be in one of a couple of locations for Lightroom to see the profile. Since you can see the printing profiles, then I suggest confirming that the profile you wish to use is in that same folder, and then it should become available under "other."

Without knowing your specific OS, it is difficult to offer a precise location.

Thank you, I will look into it.

Lightroom's color model is inherently RGB, so it will not export to a gray scale ICC profile. Luckily grayscale images work just fine in RGB color spaces, so there really is no point in exporting to a grayscale profile. Also if you want to export to any other profile than sRGB, Display P3, adobe RGB, or prophotoRGB (for example a printing profile for a printing service), you should use Lightroom Classic. Lightroom Cloudy is not able to do that.

Actually, there is a point to exporting in grayscale. The images I want to export are already grayscale images (16-bit TIFFs); but if I export them as RGB, the file size increases about three times with no benefit that I can think of.

But back to my question, can someone please look at the Color Profile options under "Other" in the Lightroom Export panel, and tell me what you see?

Exporting is normally done with one of the RGB profiles. The grayscale profile you are referring to I think is chosen in the develop module to assist in editing. It isn't an export profile.
