How to enable Adobe Camera Raw in Photoshop?

Question

The `Adobe Camera Raw` filter is greyed out, how do I enable it? I am using `Adobe Photoshop CC 2015`. I have a JPG file that I opened up in the Photoshop editor. In the layers panel I right clicked the layer and selected `Convert to Smart Object`. I then tried to go to: Filter > Camera Raw Filter ..but this option is greyed out. Not sure why? Might it be that the image mode is incorrect? It is currently set to: CMYK Color | 8 bits per channel I hope someone can help me with my confusion.

Answer 1

Color mode needs to be RGB 8/16 bits, wont work in cmyk. if your doing this for print, finalize edits in rgb then convert to cmyk
