Re: Loss of Robert OToole

I too am very sad of this news. I would always give his many posts a priority look, since they were always to exacting and good. :(

Re: Reversed lenses--usefulness of electrical contacts to control aperture?

That is pretty cool! There is the Neewer NW-C-UP electronic reversing ring that works on Canon EF lenses. I have it and it's been fun but I don't take it out much. It can help to get good images with the right lenses: https://www.flickr.com/photos/johnhallm ... 592459772/

Re: "naturefold" -- field photography with Laowa 2.5-5X and focus stacking

I have seen him before on YouTube, and he is remarkable. I think the method involves sort of leaning on the edge of the diffuser for stability, and gently pressing forward as you stack.

Re: A Few Carnivorous Plants

Very interesting! Perhaps in rainy places, pitcher plants have a lid on their trap to keep out the rain. The species near me does not have that.
I did not know that thing about Jack in the pulpit.

Re: Hamuli

Interesting. There are other mechanisms that insects use to hook the fore- and hind wings together.

Re: Platynereis dummerilii portraits

Very cool! I wonder if the lighter spots are secondary light receptors, like insect ocelli.

Re: Hungry beetles munching on pollen (GIFs)

Always of great interest to see your stuff. I have a parallel habit, where periodically at work I will see some Psychodids in the mens' room, so back I come with a vial to collect one.
