Chuck, I've been using the Canon 540 that you like on roughly the same setup 
with some success.  Would like to see a photo of the surface the insect was on. 
 I have a lab scissor jack mounted on a tripod but never thought of tilting it.

No, not a standard OM cable release.  This is what we were using

which I bought specifically for the E-M5 but it looks like it will work 
on all Oly E-thingies.

Dr. Flash was there but appeared to be a bit flustered.  He had assumed 
that the twin T-32s even operating at half power in manual would 
overpower the camera's minimum 200 ISO.  Frustration arose after much 
experimentation showed that the flash arrangement was simply not 
responding in an expected fashion.  Ultimately it did end up that most 
of the exposure variation was done with ISO on the camera but only after 
finding flash positions and settings that appeared to be producing 
repeatable results.  And your suggestion of using the polarizers might 
just have been what was need to tame the flash power at such close 
settings.  And, of course, operating in manual mode we wouldn't have 
been dependent on the response of the auto sensor to oblique angles and 
shading.

The T-32s are the right thing to use for size but the wrong thing to use 
for manual control.  Maybe the polarizers and some ND filters would make 
a big difference.  I'm sure it can be done but we ran out of time 
yesterday.  Next year we'll be smarter.
