konkav – konvex (PiP)
Macro Mondays – Mo. 04.05.2020: Diagonale Linien
Do you can see the optical illusion?
In the main picture it looks as the tiles are swales (concave). In the thumbnail (PiP 1) which is the same picture, you can see that is not! The tiles are elevated (convex), as it should be.
It's the same effect as ► HERE (in PiP 4).
This effect is called ► The Hollow-Face Illusion.
Why this effect appears here (at same picture with different size) I can not answer. :-)
► PiP 1: thumbnail 100x100 of the main pic.
► PiP 2: version 240x240 of the main pic.
► PiP 3: version 500x500 of the main pic.
► PiP 4: the tiles.

beim Ersten Blick sehe ich das Konkave, dann, nach demn Pips das Konvexe, und es scheint unmöglich den blick wieder zu "wenden". Erst nachdem ich zu eine anderen bild weitergegangen bin, und dann wieder zurück.
Immer wieder ein erstaunlicher Effekt! Ich habe es ja erst bemerkt, nachdem ich das Bild hochgeladen hatte. :-)
