Pinnate leaf patterns against the sky - staghorn sumac
D280-2015 Sumac against the sky make an interesting pattern.
To produce the outlining on the leaves, I selected for 'not sky', applied Topaz Labs Simplify Line and Ink set, Black Line Only filter, then applied Photoshop's blend mode 'Multiply' to block out all the white and leave only the black outlines.
