The reflection of the wings creates an optical illusion that makes it appear that the underlying goose has twice as many wings , ciao Giangiorgio

An amazing capture! Well done. Todd

Grazie Mille Giangiorgio! It's one of those lucky moment shot, it's impossible to plan for reflection :-)

Thanks Todd I always wanted to get multiple birds sharp but with my Canon 7D II + 500mm F4 it's ver hard to get such image because of the shallow depth of field. It's a lot easier to get multiple birds sharp with a 4/3 system. Of course, it also helps having a zoom lens that I can zoom back and incread DOF even more.
