I have Photoshop 2019 on my iMac. About a week ago, I upgraded the operating system from Mojave to Monterey. Today for the first time since updating the operating system, I found that I get a black preview when trying to use radial blur or lens blur. I get a preview with all the other types of blur? What is wrong?
Everything in the radial blur box is black, except the slider and check buttons. The previous person replying to you attached a link which indicates Photoshop 2019 has limited compatibilty with Monterey. It appears I will need to upgrade to a newer version of Photoshop. Thank you, both, for your replies.
