Not the best of weather for our club outing to Cambridge Botanic Gardens to practise some macro techniques as it was windy and overcast. We spent a lot of time in the flower beds in front of the glasshouses that have been laid out specifically for bees. A lot of the Bunble bees are infected with mites as in the first image but they seem still to be functioning.
I also tried some focus stacking changing focus ring manually on a tripod (last two images) but will need to give less exposure next time (I had set half stop over) as the highlights are generally burnt out in my images.
