Summary
[edit]DescriptionThe sun, street light and Parallax edit.jpg |
English: I've noticed that the reflection of the sun is seen at the reflection of the street light while the sun itself is much higher than the street light is. I've asked Andy Young to explain my image. Here's what he says:
"the answer is Parallax. The reflection in the water shows the view as seen from a point that is the camera's reflection in the water -- i.e., as far below the surface as the camera is above it. The street light is much closer than the Sun; so parallax mainly affects the position of the light's reflected image. These perspective effects are *always* present in pictures of reflections in water -- but not often as obvious as in your picture, which is a "textbook example" of the effect." Français : Le soleil et un réverbère. Dans le reflet, le soleil et le réverbère sont alignés, alors qu'ils sont plus loin l'un de l'autre dans le ciel. Cela est dû à un phénomène de Parallaxe. Le reflet dans l'eau n'est pas une image inversée de la scène vue par l'appareil photo, mais montre la scène vue depuis un point correspondant au reflet de l'appareil photo, c'est à dire beaucoup plus bas.
Deutsch: Sie stellen fest, dass sich die Reflexion der Sonne in Höhe der Straßenlampe befindet während sich die Sonne selbst deutlich höher als die Straßenlampe befindet. Laut Andy Young wird dieser Effekt durch die Parallaxe erklärt. "Die Reflexion im Wasser ist an der Position, an der sie sich aus Sicht der Kameralinse befindet, so weit unter der Wasseroberfläche, wie sich die Kamera über ihr befindet. |
