… using a vintage Helios lens with an extension tube and a very narrow depth of field… well… it's a challenge… and this baby didn't want to sit still… :-).
When I was on my computer I looked it up - it's a female Pieris Napi, a green-veined white (in Danish: "Lille grønåret hvid sommerfugl"). It's a very common butterfly here in Denmark, and I think it's very pretty.
