I went on holiday to the Peak District last week...
naturally I took my camera gear and carried it on long walks...
well to cut to the chase I went to walk in Lathkill Dale near Youlgreave..
I wanted waterfall shots, so I had my 18-55mm attached and a circular polariser, AV mode F/22 (if I remember)
I then spotted a few wagtails, I think grey wagtails, and of course wrong lens... changed lens quickly and quietly to a 150-500mm, bird flew away....
so I swapped back to short lens having missed a golden opportunity. (they were less than 4m away!!
I took some more pictures of a very dry waterfall, wiped them from my card pretty quickly.
But, as I was waiting for the card to wipe, a dipper wandered past in the stream nearby (apparently they are quite rare and recently scared away from this area by an over zealous snapper

)
then I didnt see another bird for 10 mins... until i spotted a kingfisher....
which dived and then flew off with a fish...
swapped to big lens as i walked downstream and lo and behold, I got some blurry pictures of a kingfisher because my lens didn't quite focus right, and the OS didn't like 1/250th for some reason!! (I was resting on a fencepost)
but I finally got some pictures of a heron.... so 1 out of 4 birds photographed!
and no decent pictures of waterfalls...
the moral of the story is when it has been a dry summer, photograph birds, not waterfalls!!
Will
PS heron pics coming soon!!!
