Anyway to remove banding (caused by HSS) In Affinity Photo (iPad)

[Athiril]

Attached a picture.

Its caused by wrong settings with high speed sync flash.

 

wonder if there is anyway to counteract it by subtracting lines? Like generating a series of black and white lines of certain frequency and softness? (How?)

 

filter frequency?

 

Im not sure
