 ## How it works
 
-The illustrations below show alternative capture arrangements and a proposed operator interface. They are AI-generated concept illustrations, not installation drawings, real defect evidence or screenshots of implemented software. Geometry and defect appearance are illustrative and not to scale. Teal cones represent camera fields of view; amber rays represent illumination.
+The illustrations below show alternative capture arrangements and a proposed operator interface. They are AI-generated concept illustrations, not installation drawings, real defect evidence or screenshots of implemented software. Geometry and defect appearance are illustrative and not to scale. Teal cones represent camera fields of view; amber rays represent illumination. The web continues beyond the image boundaries; transport and winding equipment are omitted. Magnified insets make subtle surface details visible without implying large deformations.
 
 ### 1. Complementary views of the same surface
 
 ![Two cameras view the same membrane surface: an overhead view with diffuse light and an oblique view with low grazing illumination.](docs/images/complementary-views.png)
 
-Camera A observes the surface approximately perpendicular to the web; camera B adds an oblique view. Diffuse light reveals surface appearance, while grazing light can make raised features visible through highlights and shadows. Both views target the same inspection region. In experiments, switch lighting recipes separately when needed to distinguish their effects; the drawing shows the available sources together.

 ### 2. An alternative: inspect both surfaces
 
-![One camera and light above the membrane and another camera and light below inspect opposite surfaces across an open span between rollers.](docs/images/both-surfaces.png)
+![One camera and light above the membrane and another camera and light below inspect opposite surfaces on a freely passing web with transport equipment omitted.](docs/images/both-surfaces.png)
 
 If both surfaces matter, place one camera and a suitable light on each side of an unobstructed span. Each camera inspects its own surface. This is an alternative to the complementary-view arrangement, not a requirement for four cameras. Mechanical clearance, coverage and triggering still need to be established.
 
 ### 3. Detect, highlight and review

 The proposed interface displays the latest captures and highlights a suspected defect on the matching image. The operator confirms or rejects the suggestion; the catalogue retains the image evidence and review history. Optional generated descriptions arrive later and do not delay the alarm. The illustrated monitor shows the complementary-view scenario above; it does not demonstrate detection accuracy.

 # Concept illustration sources
 
-Created on 2026-09-09 with the built-in Imagegen tool. These are conceptual, AI-generated illustrations, not engineering drawings, measured results or application screenshots. Original PNGs are stored alongside this file and referenced with relative paths in the project README.
+Created and revised on 2026-09-09 using the built-in Imagegen tool. These are approved concept illustrations, not engineering drawings, measured surface profiles or application screenshots. The current camera illustrations use revision 3 (free web, no rollers); the monitor uses revision 2 (subtle surface imperfection). All three PNGs are stored alongside this file.
+
+Target examples supplied by the user: chatter marks, shallow imperfections approximately 2–5 mm in diameter and 0.1 mm deep, and orange-peel texture. Insets are illustrative magnifications, not calibrated measurements.
+
+## Final camera edit — revision 3
+
+Applied to both revision 2 camera illustrations, preserving their lighting and surface-detail insets:
+
+Edit only the material transport geometry in this technical illustration. Remove BOTH large cylindrical rollers/reels at left and right, including their axles, bearing blocks, feet and roller-specific mounting supports. Replace the curved/wrapped end sections of membrane with a straight flat continuous black membrane web that simply extends beyond the LEFT and RIGHT image boundaries, as if freely flying horizontally through the illustration. No visible ends, no winding/unwinding areas, no rollers, no conveyor bed, no replacement support equipment. Keep original perspective. Preserve all cameras and lights and THEIR supports, teal fields of view, amber light rays, original English labels, travel arrow, magnified surface detail inset and its leader, subtle nearly-flat orange-peel/chatter/dimple texture, white background and polished illustration style. Keep the inspection surface planar; no folds or dramatic damage. Everything except the rollers and membrane end geometry should remain as close to original as possible.
+
+## Surface correction — revision 2
+
+Applied to the original three images; the monitor from this revision is the current final monitor.
+
+## complementary-views.png
+
+Edit the supplied illustration. Preserve its professional styling, composition, equipment, camera/light geometry and typography. CRITICAL correction: real target defects are VERY SUBTLE surface finish defects on almost flat black membrane: fine chatter marks (faint repeated transverse bands), local shallow depressions 2–5 mm diameter and about 0.1 mm deep, and orange-peel microtexture (black material, not orange color). Absolutely NO raised folds, tears, open holes, peeled flaps, mountains, craters or severe deformation. Dimensions describe intended defect scale, NOT measured results. Surface should appear nearly intact; defects mainly detectable by slight grazing-light reflection changes. Replace the giant central mound with an almost invisible patch of faint closely spaced chatter bands on a flat taut sheet. Add a clean circular magnified detail inset in unused lower whitespace, with a thin leader to inspection region, showing subtle parallel satin reflection bands and a tiny shallow dimple, with no exaggerated relief or deep shadows. Label inset 'Magnified surface detail' and small 'Illustrative'. Keep all original camera/light labels. Main sheet must remain flat.

Show only very faint local orange-peel microtexture in the inspection zone, visible as subtle variations in reflected light, not nodules. Add a small circular magnified detail inset in unused upper-right whitespace, thin leader to inspected region, showing black fine orange-peel texture and a very shallow softly edged tiny depression. Label 'Magnified surface detail' and 'Illustrative'. No red physical damage. Preserve upper and lower inspection arrangement.

Surface should appear nearly intact; defects mainly detectable by slight grazing-light reflection changes. Replace BOTH camera images and the human review crop. Show a continuous almost flat satin black polymer surface filling the camera images, no sample sheet edge, no folds. Camera A diffuse light: a tiny faint round shallow dimple barely visible; Camera B grazing light: same subtle dimple more discernible by gentle reflection gradient, plus faint fine chatter bands in surrounding surface. Red thin rectangular detection overlays tightly enclose the small dimple; DO NOT paint the defect itself red, no opaque mask. Review crop is a magnified close-up of the same shallow dimple, softly edged and barely depressed, embedded in fine black orange-peel surface finish. Small review heading 'Magnified detail'; retain 'Surface anomaly', 'Unreviewed', Confirm/Reject and CONCEPT UI. No depth measurement, no confidence or accuracy. Overall visual message: software finds subtle imperfections that a human might overlook, NOT dramatic damage.
