The spider was wandering on a dilapidated wooden window. The sunlight was hitting brightly on the surface where the paint had peeled off and this reflected light lit the tiny hairy spider which stood out again the dark painted surface of the window.
The photo was taken on Microsoft Lumia 640 xl. And I carried out some post-processing in Fantasia Painter app (Mobile app). Here I desaturated the colour to emphasize the light, added some contrast and finally cropped it to remove some distracting elements.
