Currants...

..of the white variety.
I also have red ones in abundance and some pink ones somewhere.
This close they almost look burnt or branded at the bottom. And I'd never noticed that the bottoms were pentagons.

It was great to get out there for a couple of hours this evening, bramble cutting and rubble gathering up after the penultimate day's training.

Still struggling with the focus/depth of field thing with the tubes. Meant to try using live view and then forgot. A proper macro lens one day will be a joy. Alternatively maybe I should start taking things off plants if I can't get them deliberately and obviously in or out of focus!
