Trying to use Local Adjustments. When I choose to alter colour and light, and press the preview Delta E button, I quite clearly see the mask. However, when I try to use one of the non-colour adjustments, eg blur and denoise, the image is still shown without any mask. I watched the Andy Astbury video on the topic, and I cannot see what I am missing.
I am using RT 5.9 on Windows 11.
Thanks for your help
