How to use Soft Proofing within Camera Raw filter

"No, you cannot use the Camera Raw Filter on CMYK images. The Camera Raw Filter is specifically designed to work with raw image files, which are typically in the RGB color space.

The information you found on a website is incorrect.

While it is true that the Camera Raw filter doesn't work with CMYK files, it is not designed to work with raw files.

The Camera Raw plugin (for Photoshop and Bridge) is designed to work with raw files – it's a raw converter. Raw files are not RGB files, they are grayscale files, and the plugin renders an RGB file from the raw file that opens in Photoshop.

The Camera Raw filter cannot be used with raw files, it is designed to work with rendered (RGB) files from within Photoshop.

Who said anything about cmyk?

I print my own images on a fine art printer using different papers all of which are RGB.  Each paper has a different profile which I can soft proof outside ACR but as I said in my original question it would be very helpful to be able to fine adjust within ACR using thePS RGB soft proofing function.

Ok, just saw this bit on a website, you cannot use camera raw with cmyk images, because this tool is made for rgb images.

So a feature for soft proofing to a cmyk profile in camera raw  would be useless anyway.

"No, you cannot use the Camera Raw Filter on CMYK images. The Camera Raw Filter is specifically designed to work with raw image files, which are typically in the RGB color space. CMYK, on the other hand, is a color model used for printing purposes.

The Camera Raw Filter offers a wide range of adjustments and enhancements for raw images, including exposure, white balance, contrast, and color correction. These adjustments are based on the RGB color space, which is different from CMYK. RGB uses additive color mixing, while CMYK uses subtractive color mixing.

When you try to apply the Camera Raw Filter to a CMYK image, you will receive an error message stating that the filter is not available for CMYK documents. This limitation is due to the fundamental differences between the two color spaces and the specific functionalities of the Camera Raw Filter.

To edit CMYK images, you would typically use other tools and adjustments available in programs like Adobe Photoshop. These tools are specifically designed to work with CMYK color space and provide the necessary adjustments for printing purposes."

Oh yes, please add the possibility to soft proof inside the camera raw filter, it is so much better to edit in camera raw than with adjustments layers. This feature would be a must-have for those who want maximum control over the colorimetric rendering of their prints!
