Tilt-Shift Miniature World Collage

1:1, 2x2 grid, AI picks different subjects: INTENT selective attention made geometric; miniaturisation, or a slice of focus cutting across the world UNKNOWNS tilt angle ; hinge distance J = f / sin(tilt) ; aperture N ; focus distance LAWS Scheimpflug subject plane, lens plane and image plane extended meet in ONE common line ⇒ tilting the lens TILTS the plane of sharp focus in the world hinge rule the focal plane pivots about a hinge line parallel to the lens plane at J below it ⇒ the in-focus volume is a WEDGE: zero thickness at the hinge, widening with distance. Near sharp band NARROW, far sharp band WIDE — a lawful, monotone flare. the inversion sharpness is governed by distance FROM THE TILTED PLANE, not by depth. ⇒ objects at very different camera distances can be equally sharp if they lie on the plane ⇒ objects at the SAME camera distance can differ in sharpness if one sits off it (⇒ the "equal depth ⇒ equal blur" FORBIDDEN of the thin-lens prompt is here REVERSED — which is exactly why fake tilt-shift is detectable) vertical objects a lamppost, tower or figure standing across the plane is sharp only in the BAND where it intersects, blurring above and below — but that band's HEIGHT varies with its distance shift rise/fall keeps sensor parallel to the façade ⇒ verticals stay PARALLEL while framing high; the horizon sits off-centre. Cropping a tilted-up frame instead leaves converging verticals. aperture stopping down widens the wedge; the bokeh still obeys one aperture, one blade count OVERDETERMINATION the plane recovered from ≥3 sharp features at differing depths — one plane fits all; the wedge's widening rate must agree with the recovered tilt and N HONEST one tilted plane; sharpness monotone in distance from it; the sharp band widens with depth FORBIDDEN a blur gradient that is a function of IMAGE HEIGHT rather than of distance from a world plane (the post-filter tell: an even soft band top and bottom, ignoring the scene's geometry) ; a sharp band of constant width from foreground to horizon (no wedge) ; two objects on the same recovered plane, one sharp and one soft ; a tall vertical uniformly sharp along its whole height while the plane clearly crosses it ; "shifted" architecture with converging verticals, or unshifted verticals with a centred horizon that the framing contradicts ; miniature-faking by blur and saturation alone with a ground-level viewpoint no model would have.
