Lens correction tool not available.

[La sardegna]

Hi,  I am trying to use the lens correction tool to fix a vignetting problem, and it's "greyed out" (not available).  Can anyone tell me how I can get this tool back in use, or if there is a help service available for Photoshop that I can call? thanks!

Check to make sure your document is in RGB color format not CMYK or Grayscale.

I have the same issue in lens correction vignetting is greyed out - RGB color mode - also (perhaps related?) the shortcut (SHIFT+CRTL+R) for Lens Correction doesnt seem to work (but other shortcuts work as normal) - I've worked around this by making it manual but its annoying to not know what causes this problem (it has worked for me in the past)

If possible, please share a screen capture of your image within the workspace.

this one was user error guys - I didnt select the camera model and thus vignetting was greyed out - still no solution to why SHIFT + CTRL + R doesn't work but thats not much of a problem

hopfully someone reads this one day and benefits from my blunder

Reviving this old thread.
Letting you know I had this same issue; fixed it by converting the file to RGB as it was in CMYK for those who are also having this issue. Cheers.
