Nice catch. You should try oblique, think you will find they are more visible that way.
Almost missed this - would have expected it to be in Pictures and Videos

How do you achieve oblique illumination ? I know about Flèche de Mathias and filters, but none of them (which I tried DIY) worked properly at the moment.
Very cool amoeba, I'd love to catch one, their pseudopods are alien-like. Fascinating.

There are several ways (and types) of Oblique illumination - all require trial and error and a little patience.
A quick and serviceable Oblique can be had by partially offsetting the brightfield port on a circular condenser while playing with the condenser diaphragm setting.
These two links provide a more nuanced Oblique:
van Egmond masks: viewtopic.php?f=15&t=4499
Gradient Universal Filter: http://www.photomacrography.net/forum/v ... hp?t=15142

Oh yeah, the van Egmond Mask, I tried it too ! it was a failure aha. To be honest, I don't really know where to put such masks. Most of them are between the condenser and the light path, but I have no idea how to hold them, filter slots ?
The Gradient Universal Filter is interesting, i'll try it asap. Thanks !

I will try oblique next time. And post video's in Pictures and Video's.Nice catch. You should try oblique, think you will find they are more visible that way. Almost missed this - would have expected it to be in Pictures and Videos
