inverting multiple iSRD masks in Studio HDR

[HistoryScan]

I scanned slides to 64bitHDRi. In Studio HDR, I selected the iSRD function.
I want to apply iSRD Automatic correction on the entire slide with the exception of 2 areas.
I created masks for each of the 2 areas and inverted each mask so they would be excluded from the iSRD automatic correction.
However, I can only get the exclusion to work for the mask which is selected, not for both masks at the same time.
How do I create multiple masks, inverted, and have both effective at the same time.

Dear customer,

instead of creating two masks try adding to the first mask.

You will need to add the second area before you invert the entire mask.

Adding a second layer will not work for what you are trying to do.


Kind regards,
