Interesting fungi! The name seemed familiar, from long, long ago, and so a quick look confirmed that the "Pezizacea" are a group of fungi that tend to form cup-shaped fruiting bodies.

Very good. These come into our house in the winter over here. Being starved for buggy companionship during these cold months, I don't mind them.

Very nice stuff! I was going to ask the same question about getting the eyes "right" after inverting the brightness channel. Again a very nice technique that I should like to try one day.

Very interesting. The little round thingies swimming past the yeast cells are likely bacteria. Out of curiosity I learned that this is essential, as bacteria are critical for the flavor of sourdough. See here for example: https://asm.org/Articles/2020/June/The- ... Microbiome

Very nice work!

Well done! One of the more challenging things to do in the hobby, I would wager.

I think it could be. But your application is different so its hard to know how they compare.

I am sorry I did not see this earlier. I had wondered about using the clamp-on cell phone lenses in rigs like this, or go-pro lenses. The magnification here is beyond where I normally go, but it still looks interesting! I don't know if it would be your thing, but this reminds me of the rig made by J...

Wheel bugs (really big assassin bugs) are fearsome in that way. They don't seem to be around in my area, but I remember encountering them elsewhere. I would never pick one up. Nosir.

Interesting! These are strange, even for lichens.

Arranging for an out of focused background would be best. A black one seems appropriate. A white background probably would not show the filaments well.
As for other backgrounds, I like to use paint swatches, which are free from hardware stores. All varieties of colors are possible then.

Very nice. They look translucent here.
A conspiracy of assassin bugs?

Those are superb! Amazing!! I recognize the first one as one of the odder kinds of Cerambycids (long horn beetles).

Impressive depth of focus on the first one!
Is the second Vorticella?

Here is a summary of photo sharing services, with notes about cost (if any), etc. https://en.wikipedia.org/wiki/List_of_image-sharing_websites. I've been on Flickr, and recently transitioned to Flickr Pro. No ads then. I know you can set whether the pictures are public, or are restricted. But that i...
