Playing with the manual settings on the HX5V again. The bulb is a 60 watt incandescent and I adjusted the f-stop and exposure time so the details could be seen.

In the obvious next step from the straight lines of Pick-a-Stick, curves are plotted between the successive points in the strange attractor. The artist is of the opinion that the results are among the most beautiful available on pixelbrain so far, and has so far amassed several engrossed hours watching them emerge out of the darkness. (These, more than any so far, are worth launching the applets for...)
Created using Processing.
See pixelbrain for more, and try out the applets to watch the images being formed.
Another diagram for the Multi-Plane Camera. Note the rather excellent hand lettering. Also, the corners on the matte are perfectly angled. Attention to detail! Also, something to do with filaments

In this image, a compilation of three independent Sminthurides cf bifidus/penicillifer found in the same sample, male, female, female. I picked the largest specimens from the sample.
(left to right, image I, II and III)
In image I, 2 branches are visible and the tip of the unguiculus (uu).
In image II, 3 branches are visible and the the tip of the uu.
In image III, 2 branches of the filament are visible and the tip of the uu is hidden - probably due to the angle of the specimen.
Literature research;
I learned that the apical filament is branched, but this filament is not a direct extension of the tip of the uu. Thus, NaOH is not useful to deter an assumed separation of the filament and the empodium.
Tough one, but I found some text about these species. Fjellberg lists penicillifer as having many branches. In his drawing (103C; page 180), the filament on claw 3 is drawn with many branches, but the tip of the uu is also drawn and deviates. see also drawing (104F, page 180).
Ferreira et al. (2021) describes Sminthurides bifidus as having 2-3 branches in the apical filament. Here also, the drawings distinct the tip of the uu from the apical filaments.

R7s J78 halogen tube linear (78mm) 150w. The filament has become so distorted it is starting to melt it's way through the glass.
