When I am enhancing the iris, the tools apply changes to the entire circle of the iris, even if it is only partially visible. For most photographs, this is the usual case. Part of the iris is normally behind the eyelid.
And, for iris enhancement, the Mask Tool is not available. The menu pops up, but the tools are greyed out.
So it is impossible to change the iris hue correctly. See attachment.
Is there a way to do this?
