Re: ...two little babies on the way...

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.

Re: Sourdough seen under a microscope (VIDEO)

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

Re: Macro with inverted M12 and phone lenses anyone?

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

Re: Macro with inverted M12 and phone lenses anyone?

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...

Re: Assassins in training

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.

Re: Various Seed Pods

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.

Re: Beetles from my collection

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

Re: Photo sharing services in 2021

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...

Spiders up to something

Here are some pictures of spiders that are being spiders. Given their priorities, this will be either about reproduction or predation. Cellar spider (probably Pholcus phalangoides ) caring for her egg sac. She will hold them like this until her babies hatch. https://live.staticflickr.com/65535/47981...
