Re: Best Canon mirrorless body
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 where I take a picture of a gray card, then in the camera's menu system I tell the camera to set a custom color b...

Re: Best Canon mirrorless body
I also use Linux and find it vital to be able to do tethered capture now that I finally set it up. I just use gpohoto2 and it looks like entangle might be based on the libgphoto library? Yes, Entangle uses the libgphoto library but I know nothing about it, nor gpohoto2. Does gPhoto have a graphical...

Re: Micro double terminated quartz crystal
This is a micro double terminated quartz crystal that I mounted on a slide with tragacanth, thanks to Steve B for instructions.

Re: Best Canon mirrorless body
Adalbert, do they make image acquisition software like the EOS Utility for Fujifilm? On my Linux machine, I use Entangle. If not, that would be a deal breaker for me. I've exclusively use a Canon 50D (since it was released) and most recently the 90D. I would say 80% of the time with my microscopes a...

Re: Optiphot Bertrand head
Pau,
I have absolutely no personal experience with the bino being discussed but willing to experiment with one if owned. I would much rather have the intermediate Petrographic POL Analyzer with the Bertrand lens that Nikon made for the Optiphot/Labophot.

Re: Optiphot Bertrand head
Also out of curiosity: why did they make it? Was it just the ease of use, or does it have other advantages? Currently, I view petrographic interference patterns by removing the eyepiece and looking down the tube. With a binocular head with a built-in Bertrand lens you can see the back vocal plane o...

Re: Will we ever have a "perfect" stacking software?
I am just curious. Has anyone tried the deconvolution plugins available for ImageJ? I haven't. I've read about them for a few years.

Re: Micro double terminated quartz crystal
Any suggestions on what to use for a smooth black opaque glass background, non-textured surface? Used to place a 300um to 400um crystal on for photographing.

Lottery card shavings - Wild M400
I thought this was rather interesting. It's very impressive when viewed directly through the eyepieces, though. The stereo images were generated with Zerene.

Re: For you micro-mineral photography people, how do you deal with holding minuscule, fragile specimens?
I am more interested in mounting it on a slide at the moment. With the help of Steve Beats I have a solution. I will also try mounting one on a tungsten needle with a microscopic dab of clear nail polish, then mount that on my ball stage.

Re: Zerene --> Blender --> Sketchfab: essentials for newbies
That should be very helpful for those wanting to give this a shot. If using Blender to do this, I think diving into Blender's Sculpt mode drastically improves most extrusions. Zbrush, a stand-alone program, is more complicated but has more features. I found this Youtube video very helpful. https://w...

How would you mount a micro quartz crystal 450um or so long and 250um wide?
