I learned long ago that elimination of translation movements during stacking gives a sharper result, so I now turn off all corrections. Key to being able to do this is to ensure no movements. Capturing during a fast flash can help individual images, but if image to image movement is large, translat...

Do you all set a wb on the canon bodies even when shooting at high mag (like 10x+) with objectives? I've been meaning to ask, since I just default to 5500k fixed for the flashes. I didn't know if a white balance reference would break down for usefulness at high mag or not. There is nothing special ...

The larvae of these things can also wreak havoc on insect collections, for example pinned or papered moths and butterflies.

The adult beetles are covered by scales that have an interesting structure -- see viewtopic.php?f=27&t=46039 .

...some camera controls such as mode switching and setting custom color balance require touching the camera. On another note, the EOS Utility color temperature slider works for me without touching the camera? Are we talking about the same thing? Different thing. I am talking about the workflow wher...

I use Canon R7 tethered to either an M1 Mac or a Windows laptop, using Canon EOS Utility 3 for most functions: live view, image uploading typically after external shutter triggered by wire from a focus rail, and some camera controls such as exposure time and color balance. Some camera controls such ...

Some of the egg clusters that I moved indoors have hatched. Here's a view by cell phone through a stereo scope: https://janrik.net/MiscSubj/2024/YellowEggsOnLocustBark_20240420/PXL_20240422_061409108.jpg To me these look like lady beetle larvae, which would make sense given the location, time of yea...

It is true that 'in' focus items are not effected by the apodization BUT (what I believe is a major problem with photography) too many people forget that depth of field is a giant myth. There is one and only one plane 'in' focus. Depth of field is based on an assumption that we can be slightly out ...

Laowa makes good lenses but dropped this one and sold remaining supplies at about half the original list. I am confused about availability. At this moment https://www.venuslens.net/product/laowa-105mm-f2/ is showing "in stock" with a price of "$419.00 – $699.00". I'm also seeing in stock at B&H Pho...

Thanks for the info and link. That description also notes that locust borer eggs are laid in late summer and hatch in the fall, not consistent with these in spring. I searched the tree more carefully yesterday and found four smaller clusters that were exposed on flat bark so I could collect them wit...

I can't recall if I've ever pointed you here: https://www.photomacrography.net/forum/viewtopic.php?t=19582 , "False color and detail/DOF from shiny metal". It's a long thread that discusses some of the unexpected effects caused by shiny subjects and narrow-angle light sources. The short story is tha...

I was actually initially a bit more disappointed that I wasn't seeing some interesting colors, I was hoping it might do something "interesting" heh. Large NA is not a friend of structural colors. A quick explanation is that the wide entrance cone is looking at each point on the subject from a bunch...

I was kinda surprised by how dark it was when illuminated with flash at any angle I'm guessing that "any angle" refers to the flash, not the material. And then I'm wondering if what you're seeing is essentially the "black hole" that occurs when a lens looks at a mirror surface and sees only the ref...

Crossed-eye stereo: https://janrik.net/MiscSubj/2024/YellowEggsOnLocustBark_20240420/IMG_4397-4398-stereo_cropSmall.jpg This is cha-cha stereo, one shot for each side, standing on a ladder with hands braced against the tree. Camera was an ancient Canon A710 in Av mode at f/8, manual closest focus wi...

I have high hopes that eventually someone will construct stacking software that is either perfect or at least appears to be. I expect that such software will work like this: Run some basic stacking algorithm, similar to what we have today. Use the results to construct a model of the 3D structure and...

Very interesting thread, about the last stereo pair i read external muscle and to me (pretty ignorant in insects weirdness) it seems a really strange feature, are you sure abut being a true muscle? Pretty sure, yes. There are numerous articles in the scientific literature that have studied the stru...
