Thank you gentlemen! I really appreciate you stopping by and commenting.
Obviously, i used zooming while multi-exposing (in camera). I did try to use the wind motion to get "moving" daffodils, but that didn't work out so well (not enough wind maybe).
By the way, it seems that the nikon d850 also saves the individual images to card, as well as the blended multi-exposure one. I didn't know that and i don't remember the d810 doing that. Someone mayb e know whether this is a setting or indeed the intended behaviour?
