My tiny Pacific Swallow pal showed up again today.  With the 280mm f/2.8 APO-Telyt-R attached to the CL today, it was a good chance to do a comparison with the shots I got the other day in similar light with a non-Leica 300mm lens.

 

This was shot at about 3.5 meters at f/4 and cropped at about 60% . . .

A thank you is not enough for this shot! You make the CL sing.

I love your photographic skills. This is beautiful but it looks like gunk polluted with petrol.

Actually, I have seen this occasionally, but never realized the cause. I always thought was an oily residue of the algae.

I have friends who are doing research on this. A Finnish friend of mine published a paper in an OSA (Optical Society of America) journal (a special issue of Applied Optics) even growing algae in buckets to study the effect of globular species. You have to know where to look. It is quite common in or rather on Scandinavian lakes in June. I have only seen it on water three times. Another possibility are dusted mirrors lit by torches. Pollen grains also produce Quetelet rings. But back to photography! Edited by EUSe
