These are still shots taken of the same subject as in the Spirogyra and Trachelomonas video.
Curious how the internal spiral has contracted in the Offset Darkfield Stop image. All three image sets are next to each other in the "virtual film roll" (i.e. consecutive image numbers), though the Offset was taken last.
Order was Brightfield stills, Darkfield stills, Darkfield video and then Offset.
