Re: Wasp Stinger 5x
Nice, what f-stop did you use? I usually get so much chromatic abberation when using the MP-E at high magnification. And did you use any post processing to get rid of it? However, are you sure it is a wasp? Every wasp I know is hairless. The subfamily Vespinae, e.g. Vespa , Vespula and Dolichovespul...

Re: Another darkling beetle, Eusattus muricatus
Nice images, their roundness reminds me of Bolbelasmus , guess digging does that to beetles frustrated me that I couldn't find what colian meant, so I took a small google dive - it seems to be a common OCR error for "eolian" ie wind-processes. Which would also explain why it's hard to find a definit...

Re: Choice of processor
For what it's worth: I have tested Zerene Stacker's speed for a PMax stack with the same set of 200 images 24MP each on different Ryzen CPUs: Ryzen 2700x: 6min16s Ryzen 3900x: 5min42s Ryzen 3950x: 4min54s I'm not sure, but I would expect that the contents of the images does not affect rendering tim...

Re: Choice of processor
Thank you all very much for taking time to comment! Ok, so a Ryzen 5000X or higher seems like a good choice, I would need to get a new motherboard as well though. But to upgrade my Intel CPU it seems likely I would have to replace the motherboard anyway, since they use different sockets in their ran...

Choice of processor
I recently got a camera upgrade at work, going from a Canon 6D to a 5Dsr, doubling the MP from 26 to 51. Understandably the stacking times in ZereneStacker have also increased, to the point where the computer cannot keep up with an automatic PMax stack while the camera shoots a frame every ~4 second...

Re: Moldy bees?
It's matted hair mixed with soil, perhaps because of the rains - the bees stay in their burrows during bad weather, and these are ground nesting Andrena sp. The mite is probably not parasitic, many bees have symbiotic relationships with Acari, just look up "acarinarium" and you'll see. Andrena does ...

I would have no clue about the 3D structure, just from looking at one of the full-stack images. Hmm, but would you have an idea of the general shape of the structures from just the lateral picture? In other words, would you have understood the shapes in the very first image as being how they are sh...

Thanks for everyone's input! It gave me the idea that I can maybe try and shoot the same image with different lighting and exposure, without moving the subject, and then make a composite in PS to visually "distance" the different parts. Will be labour intensive though. Looking at some areas of your ...

Problems with rendering details
I have some annoying troubles to get details and shapes to render as "readable" in pictures of bee genitalia (it's for work, don't think I sit around photographing bee genitals for fun, no no, I only do that with cuckoo wasps :oops: ). I've tried different lighting, and experimented with different s...
