This mysterious shot prompted some interesting responses from fellow photographers, with its dark, swirling texture which fills the frame.
Alexander at World In Your Eyes thought it was part of a huge trunk, while Noeline Smith was torn between lichen or seaweed. Lucy Gutteridge said: “Looks like the surface of a Ryvita I’m currently trying to eat!”
Nearest to the mark by a long way was Sherri from Pearweed who described it as “frozen water with bubbles just under the surface”.
Well here it is – it’s simply early morning frost taken at close quarters. The frost was clinging to a length of duct tape which covered a piece of wood outside a house close to my west London home. Quite specific, then!
Since the turn of December, the weather has taken a distinctly winter turn here, with frosts, freezing fog and ice – even a dusting of snow in other parts of southern England. There will be some other frosty captures to share with you very soon.
