The macro photography looks bizarrely uniform and the poses contrived. I feel like a sleuth trying to decide if this is AI generated or not. I suspect it isn't, but I'm somewhat distressed at how suspicious I am of cool things now.
That is exactly what an AI Bot would say XDXD
So a workaround is to take a lot of photos with the focus plane at different depths. You sweep the focus plane through the scene, snapping a lot of photos as you go. This can be automatic with nice gear.
Then you take all of those photos and combined them digitally, with the algorithm selecting pixels from the photo with the best sharpness in that region. So the photo you see is a combination of many photos.
There is curiously nothing on his website about this isopod site.
Take in mind that the first page cover different morphs of the same genus. Maybe even the same species. They all look variations generated by computer, because they all are Cubaris sp and have exactly the same cephalon shape.
