Light Leak

Name	Type	Default	Description
image	IMAGE		—
leak_typeopt	COMBO	sprocket trap (perforation modulated)	Sprocket = edge falloff modulated by the KS-1870 perforation lattice. Gradient = seal/bellows wedge. Pinhole = camera-obscura spots, neutral by physics
leak_fromopt	COMBO	top	Which edge or corner the light enters from. Sprocket collapses a corner to its edge, since perforations run along the film's long edge
strengthopt	FLOAT	0.450–3	Leak exposure added, in linear light. 0 = passthrough
falloffopt	FLOAT	20020–1200	Red-channel penetration depth, ref-px @1024 long edge. Green and blue follow at 0.62 and 0.38 of it, which is what reddens the leak with distance
colour_sourceopt	COMBO	base path (derived red-shift)	Base path = the derived white-core-to-red gradient. Backing paper = 120 roll-paper dye, an honest preset. Neutral = source colour, no lateral path
diffusionopt	FLOAT	0.350–1.5	Sprocket only: lateral spreading of light past a perforation. Above 0 the comb widens and softens with depth; at 0 the teeth keep straight sides and read as a bar chart
pinhole_countopt	INT	31–40	Pinhole only: number of holes in the body/bellows
pinhole_diameteropt	FLOAT	0.300.02–3	Pinhole only: hole diameter in mm. Sets the penumbra (the 'a' term in spot size = a + D*theta)
flange_distanceopt	FLOAT	5010–300	Pinhole only: hole-to-film distance in mm. Spot size = a + D*theta, so a deeper body projects a larger spot
displacementopt	FLOAT	1000–500	Warps the PATH LENGTH so the leak boundary wanders instead of running parallel to the frame edge. Because colour follows path length, the red fringe warps with it. 0 = clean analytic field
displacement_scaleopt	FLOAT	380142–1500	Warp feature size, ref-px @1024. Clamped at 142 (5mm of seam): anything finer stops being a mechanical gap variation and reads as noise running through the effect
vary_per_frameopt	BOOLEAN	false	Batch of N gets N different leaks. Off keeps one leak across the batch, which is usually what you want for a sequence
seedopt	INT	420–4294967295	Seeds the perforation phase, the pinhole placement and the displacement warp
