Excellent cross-view stereo picture! Now you see the shape very well.
I love the cross view version.

Shorter stack times would save much time. Very sure! Through this post, my cycle has now been reduced to 50 images per minute or 1.2 sec/picture. This is now my new default value and that goes really fast (versus 2.9 sec). This has my vote for the image of the month. Amazing, artistic.. Thanks! In ...

Very interesting test. Your result is clearly positive. It has also kept me busy for several days. Hence the realization of my controllable LED flash in power and light direction. With 10 LEDs I have many opportunities. The direction I have divided in 40 parts under software control. The LEDs always...

Update glue, inspection and cleaning station.
Before going to the stacking, there must be done some preparations. First gluing the insects on a cover glass. Then to the Bino Stereo microscope for inspection and clean up. Cleaning is done with a very fine paint brush (only 2 to 3 hairs). Then it goes to the darkroom for the stack recordings. On ...

Keith, This 2.7 sec is a very relaxed speed, not the max. I just did a test with 100 recordings. At a rate of 1 sec, I've occasionally a black image ( USB speed to low versus PC load), so a little too fast. I then worked slightly slower with the following information: Mirror-up shutter delay: 500 ms...

Thanks SW_Perspective and Keith. How long did the shutter stay open? On my own LED rig I open the shutter for 2 sec with the LEDs on for approximately 1.25 sec. Your LED flash is about 1000X more powerful than my bucket light. The shutter stay 500 msec open. The first 420 msec are used to avoid vibr...

Thanks: GaryB, Jörgen, Beatsy and ChrisR. How on earth did you not get stacking artefacts among the hairs? Was it just lots (and lots and lots) of detailed retouching, or perhaps because you left out-of-focus hairs behind the in-focus ones? Or photoshop? Or all of the above. There was being done ver...

Rhingia campestris.
The new power LED module is in use. I now use a default optimal profile in order to set the exposure. The profile contains the initial value for the 10 LEDs. This profile can be rotated via software (hardware calculations in the FPGA). This is done with a potentiometer. The software calculated 40 mi...

Here a composite picture of 40 images with each exposure rotated 9 degrees. Light is rotated in hardware and software into the FPGA realtime. Object, camera and flash do not move during this test. This just in order to see the influence of the exposure. The more bright images are a reflection of the...

Chris, I did it simpler. I now use micro directional control, as with microstepping motors. The intermediate values are calculated. Now I get 40 calculated positions. The angle of light rotation is thus 9 degrees. This really works great! You can set the ideal lighting direction. This now also works...
