Re: Flesh Fly Inflating its Cooling Bubble

Thanks for the link. Very interesting. Almost all of the things they found could be just as well explained by the digestive hypothesis, but the fact that they do this bubbling behavior with higher frequency as soon as the lights go out does suggest that at least one of its functions is to cool the f...

Re: Polypodium sporangia fluorescence

I do fluorescence with no filter cube, very cheap.

Re: Flesh Fly Inflating its Cooling Bubble

Yes, that makes more sense than the thermal explanation. It may be similar to what bees do with their gathered nectar to make honey. That gives it a reason to be in the sun. If so, it is not trying to cool, just the reverse.

Re: Flesh Fly Inflating its Cooling Bubble

Very interesting. I wonder why the fly doesn't just move to the shade though. That would be far more efficient than this laborious process.

Re: Polypodium sporangia fluorescence

Maybe adding an humectant substance to the water could aid to avoid bubbles This is definitely true, and when I am shooting through water with a normal objective, I always use it. This also reduces meniscus effects that can distort the image, and I suspect it also reduces wave activity due to vibra...

Re: Polypodium sporangia fluorescence

Great use of the water objective. How did you avoid air bubbles? I tried this once but the bubbles ruined it.

Re: Euglenoids

The lighting of the last one is very interesting; it really looks three-dimensional. Extremely nice! I don't recall ever seeing that kind of light effect before for single-cell animals.

Re: New to focus stacking, feedback appreciated

They look pretty good, but I would suggest you use a uniform background (easiest is white or black, but gray also works) so that you can easily make seamless composite illustrations of several individuals for publication. Also don't forget a scale bar! If you choose to have a white background, it ma...

Re: Microscope stage Vs objective Y Axis Movement

It also depends on whether the subject is dry or in liquid. Better to move the optics if the subject is in liquid, so as not to disturb it.

Re: Yet another "what camera" question

I am deeply invested with MFT for my field work, where it excels. I used it extensively for studio macro work too, but I now use my FF mirrorless (S1R) for all my macro work, because of better resolution and dynamic range.
