it was a bokeh fun shooting session a few weeks ago when a handful of keepers were framed in one hour of saturday's evening. everybody knows that a good specimen of helios-44-2 is capable of bokeh wonders (and beautiful colour rings if shot against the sun), but has someone encountered anything similar the crop shows below? it has some kind of light spiral inside the 3d like colourful phenomena.
and no, this is not fake, it is in the raw file as well.
