Nymphea alba

White Vater Lily or Nenuphar or White Lotus (Eng)/ Vit näckros (Swe) / Lumme (Fin)

Vater lilies are so brilliant white that photographing them is a great challenge to me. I know what to do, in theory. In practice i use the camera's automatic-exposure mode, close my eyes, blip, and hope for the best.
We have another vild, pink vater lily (Nymphea tetragona) but it's very rare.
