At WW = 1801, WL(C) = 168:
Edge-dots appear outside of the higher contrast tissue region.

At WW = 1801, WL(C) = -530:
Edge-dots appear inside of the higher contrast tissue region.

At WW = 1801, WL(C) = 168:
Edge-dots appear on top of the 'true' edge-profile of the higher contrast tissue region.

At WW = 1801, WL(C) = -530:
Edge-dots appear on top of the 'true' edge-profile of the higher contrast tissue region.

By correcting the century-old Penumbral-Spread Effect, the enhanced image edge-profile is free of the 'Blooming Effect'.
