How to apply XMP while saving an image as tiff in javascript

OK, I have been playing around and it is possible to apply CRS metadata via Photoshop scripting, I have tested with exposure, white balance and vibrance.

Now I understand what you mean by "Profile".

The Camera Raw XMP metadata for using a "Profile" appears to be a little more complex, however, as this is just metadata I'm guessing that it is possible if it is supported (yet to be tested).

If I am understanding you correctly, you would like a way to script adding the Camera Raw develop settings metadata to TIFF images? By profile, do you mean "Presets" (the second tab from the right)?

I have not tested, so this is just conjecture... All of the ACR develop settings are just metadata, so in theory it will be a question of adding some/all of the required metadata to the file.

<crs:Version>12.1</crs:Version>
<crs:ProcessVersion>10.0</crs:ProcessVersion>
<crs:WhiteBalance>As Shot</crs:WhiteBalance>
<crs:Temperature>4950</crs:Temperature>
<crs:Tint>+3</crs:Tint>
<crs:Saturation>0</crs:Saturation>
<crs:Sharpness>0</crs:Sharpness>
<crs:LuminanceSmoothing>0</crs:LuminanceSmoothing>
<crs:ColorNoiseReduction>0</crs:ColorNoiseReduction>
<crs:VignetteAmount>0</crs:VignetteAmount>
<crs:ShadowTint>0</crs:ShadowTint>

...

<crs:HasSettings>True</crs:HasSettings>
<crs:HasCrop>False</crs:HasCrop>
<crs:AlreadyApplied>True</crs:AlreadyApplied>

This may be achievable via Photoshop or Bridge scripting if it is possible to write the CRS metadata, however, I personally would look into ExifTool as that would be faster for me.

P.S. I forgot to add, that the file would then have to be opened or processed through ACR in order for the metadata develop instructions to be applied and then saved to the file.
