This morning, the fresh night has sprinkle some tiny dew droplets. Excited by the promise of nice picture, I decide to walk in the wet grass with sandals. But, I'm quickly back, afraid to see spiders climbing my naked legs: I'm scared by spiders!
I put my boots on and go back to the adventure.
In the morning light, some large shadows aera highlight the spider webs. After setting my camera to avoid overexposition, I shoot a spider having its dinner. Its web displays some nice irisations, caused by diffraction of sunlight in the molecule of the silk. The processus isn't well understood, but... it's pretty! |
