Nano Banana 2 Lite vs Image 2.5：移轴微缩硬对照

提示词

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.

中文译文

INTENT     把选择性注意力几何化；微缩化，或一道横切世界的清晰焦点切片
UNKNOWNS   倾角 ;  铰链距离 J = f / sin(tilt) ;  光圈 N ;  对焦距离
LAWS
  Scheimpflug   被摄物平面、镜头平面与像平面延长后交于同一条共同直线
                ⇒ 倾斜镜头会使世界中清晰对焦的平面随之倾斜
  hinge rule    焦平面围绕一条铰链线旋转，该线与镜头平面平行、位于其下方 J 处
                ⇒ 合焦体积是一个楔形：在铰链处厚度为零，随距离增大而变宽。
                  近处清晰带窄、远处清晰带宽 —— 一种有规律的、单调的扩张。
  the inversion  清晰度由到倾斜平面的距离决定，而不是由景深决定。
                ⇒ 相机距离相差悬殊的物体，只要位于该平面上，就可以同样清晰
                ⇒ 相机距离相同的物体，若其中一个偏离该平面，清晰度就可以不同
                （⇒ 薄透镜 prompt 中「相同景深 ⇒ 相同虚化」的 FORBIDDEN 在此被反转 ——
                  而这正是伪造的移轴效果能够被识破的原因）
  vertical objects  横跨该平面的路灯、塔或人物，只在与其相交的那条带上清晰，
                上下两侧则变得模糊 —— 但那条带的高度随其距离而变化
  shift         升降（rise/fall）使传感器保持与建筑立面平行 ⇒ 高位取景时垂直线仍然保持平行；
                地平线不居中。若改为裁剪一张上仰的构图，垂直线则会汇聚。
  aperture      收小光圈会加宽楔形；虚化仍然只服从一个光圈、一个叶片数
OVERDETERMINATION   从不同景深处至少 3 个清晰特征反推出的平面 —— 一个平面即可拟合全部；
                    楔形的加宽速率必须与反推出的倾角和 N 相符
HONEST     一个倾斜平面；清晰度对到它的距离单调；清晰带随景深增大而变宽
FORBIDDEN   由图像高度、而非到世界平面的距离所决定的模糊渐变
            （后期滤镜的破绽：上下各一条均匀的柔和带，无视场景的几何） ;
            从前景到地平线宽度恒定的清晰带（没有楔形） ;
            位于同一反推平面上的两个物体，一个清晰、一个模糊 ;
            一个高耸的垂直物体沿其整高均匀清晰，而该平面明显穿过它 ;
            「已移轴」的建筑却出现垂直线汇聚，或未移轴的垂直线配上居中的地平线
            且构图自相矛盾 ;
            仅靠模糊与饱和度伪造微缩感，却采用任何模型都不会有的贴地视点。
