How do I avoid halos?

Help please. Still new at focus stacking. Happy with results in landscape scenarios so tried my hand at macro (Sony A7Riii + 90mm Macro lens). When I stacked my 421 images - too many I think - there is a halo around the edge of the flower. Image is attached. I used manual exposure and the lighting changed by just over 1 stop during the shooting. I used the Sony RMT remote to step the focus in manual mode - hence the high number of shots I guess. Any help or comments much appreciated.

Try increasing the radius parameter. A bit more about it here: https://www.heliconsoft.com/helicon-foc ... arameters/
421 does indeed sound like way too many, you may not even need 1/10th of that, but on its own having too many images should not cause halos.

For some reason the pyramid function worked better for me. Of course the radius is part of it too, but I am only doing 20 now and it seems to suffice.
